Is there a 3-minute re-login window for DU SOL MCQ Internal Assessment?

Yes, in some cases. The DU SOL server often holds your Session Token for approximately 3 minutes (180 seconds) after a browser crash or sudden disconnection. Re-login within this time on the same device and same browser. Do not use Incognito mode or a different browser. This is not officially guaranteed.

What happens if I switch from Wi-Fi to Mobile Data during the DU SOL MCQ exam?

Switching from Wi-Fi to Mobile Data changes your IP address. The DU SOL portal server sees this as a security threat and immediately logs you out. This is one of the most common reasons students get locked out mid-exam. Always decide on one network before you start and never switch during the exam.

What is the 2GB data rule for DU SOL MCQ Internal Assessment?

Before starting your DU SOL MCQ Internal Assessment, you must have at least 2GB of free, stable 4G or 5G data. Low data or weak signal causes the exam portal to crash silently while the server-side timer keeps running even though your answers are not saving.

Which browser is recommended for the DU SOL MCQ Internal Assessment?

Use Google Chrome (latest version) or Microsoft Edge. Do not use Safari, Opera Mini, or UC Browser. The DU SOL MCQ portal scripts are optimized for Chrome and Edge only.

Should I clear browser cache before the DU SOL MCQ exam?

Yes, always. Clear your browser cache and cookies at least 10 minutes before the exam. In Chrome go to Settings, then More Tools, then Clear Browsing Data, check Cached images and Cookies, then click Clear Data.

Can I give the DU SOL MCQ Internal Assessment on my smartphone?

Yes, but with precautions. Use Chrome on Android. Enable Do Not Disturb to block calls, disable Wi-Fi if using Mobile Data, close all other apps, and keep the phone on charge. A laptop is still safer because it handles browser sessions more stably.

What does Response Already Submitted mean in the DU SOL MCQ portal?

This message appears when the portal has already recorded a submission for your Roll Number for that assessment. This happens when you submitted, when the timer auto-submitted your paper, or when a portal crash was recorded as a submission. Email technicalsupport@sol-du.ac.in immediately with your Roll Number and a screenshot.

What screenshots do I need if the DU SOL MCQ assessment crashes?

You need: a screenshot of the error message on screen, a screenshot showing the exam timer when the crash happened, screenshots of your last few saved answers, and the timestamp on your device. Email all evidence to technicalsupport@sol-du.ac.in within 24 hours with subject line: MCQ Internal Assessment Technical Failure followed by your Roll Number.

What should I do if the DU SOL MCQ screen goes white during the exam?

Do not immediately refresh. Wait 10 seconds first as the portal sometimes reconnects. If it does not reconnect, check your internet by opening a new tab. If internet is working, refresh the page. If you must re-login, do it within 180 seconds on the same device and same browser. If re-login fails, screenshot the error immediately.

DU SOL MCQ Internal Assessment 2026: Can You Re-Login if Your Session Expires? — Auto-Submit Timer

The DU SOL (School of Open Learning) assignments for 2025 are an essential part of your academic journey. Make sure to check the official website for the specific last date for submission, as it may vary for different courses. Typically, assignments must be submitted online through the DU SOL portal. To submit, simply log in, upload your completed assignments, and follow the given instructions. It’s important to submit on time to avoid penalties, so be sure to stay updated on deadlines and guidelines. Keep your assignments clear, well-researched, and in the required format to ensure smooth evaluation.

DU SOL MCQ Internal Assessment 2026 — student checking session expiry, re-login rules, auto-submit timer and pre-exam technical checklist for sol.du.ac.in portal

You are 20 minutes into your DU SOL MCQ Internal Assessment. Suddenly — your screen goes white. Your Wi-Fi dropped. The timer is still running. Your heart is racing. The only question in your head is: “Can I log in again? Will my answers be saved? Is my exam gone?”

We have helped hundreds of DU SOL students through exactly this panic. And the honest answer — the one no official PDF and no YouTube video ever clearly gives you — is this:

No, DU SOL does not allow a second login for MCQ Internal Assessments once the “Submit” button is pressed or the timer runs out. If your session expires because of inactivity or a network switch, the portal may treat your partial answers as your Final Submission. Before you start, make sure you have at least 2GB of stable 4G/5G data, a dedicated Chrome or Edge browser window, and your device on charge.

This blog explains everything — the 3-Minute Re-login Window secret, the Auto-Submit timer logic, the IP tracking rule, and the screenshot strategy that can save your marks if the portal crashes. All in simple, plain language that anyone can understand.

The 3 Real Reasons Your DU SOL MCQ Session Expires Most Searched

Most students think a session expires only when the internet goes off. That is not fully true. Here are the 3 actual reasons the DU SOL MCQ portal logs you out — and the portal does not always warn you before it happens:

📶 Reason 1 — The Network Switch

If you switch from Wi-Fi to Mobile Data (or the other way around) in the middle of your exam, your IP address changes. The DU SOL portal server sees this as a suspicious activity — like someone else trying to log in from a different location. It immediately logs you out as a security measure. This is the most common and most unexpected reason students get locked out.

📱 Reason 2 — Tab Switching or Screen Switching

If you open another browser tab to search an answer, or even switch to WhatsApp/YouTube for a second, the MCQ assessment tab can go into “sleep mode” or auto-refresh. When this happens, your active session is either reset or ended. On mobile phones, this is even more common because Android’s RAM management closes background tabs very aggressively.

⏱️ Reason 3 — The Hard 45/60-Minute Auto-Submit Timer

This is the one most students don’t know about. Even if you never click the Submit button, the DU SOL portal has a server-side timer. When this timer reaches zero — whether it’s 45 minutes or 60 minutes depending on your paper — the portal auto-submits your answers automatically. Whatever answers you have saved at that moment become your Final Submission. There is no warning. There is no extra time. The timer on the server does not care if your internet went off for 3 minutes.

Quick Tip: Always keep your phone on Airplane Mode for 10 seconds, then turn only Mobile Data ON before starting the exam. This locks you into one network and stops automatic Wi-Fi switching.

The Emergency Re-Login Hack What Big Sites Miss

Almost every blog and YouTube video about DU SOL says: “You cannot re-login after your session expires.” That is mostly true — but not 100%. Here is the part that nobody talks about:

The DU SOL MCQ portal server sometimes holds your Session Token for up to 3 minutes (180 seconds) after your browser crashes or you lose connection. This means if you act fast — on the same device, in the same browser — there is a small chance you can re-login and your partial answers may still be there.

What to Do If Your Screen Goes White or Freezes

Follow these steps in order. Every second counts:

DO NOT immediately refresh or press F5.
Wait exactly 10 seconds. Sometimes the portal reconnects on its own. Refreshing too early can actually end your session permanently.
Check your internet first.
Open a new tab quickly and check if any page loads. If your internet is working, it is a portal-side issue and refreshing is now safe.
Re-login within 180 seconds (3 minutes).
On the same device and in the same browser (not a different browser, not Incognito mode), go back to sol.du.ac.in and log in with your credentials. The session token may still be active.
Do NOT switch networks during re-login.
If you were on Wi-Fi when the crash happened, stay on Wi-Fi when you re-login. Switching will give you a new IP address and permanently lock you out (see Reason 1 above).
If re-login fails — take a screenshot immediately.
Take a screenshot of the error screen, error message, and the time shown on your device. This is your only official evidence for requesting a re-test.

This 3-minute window is not an official guarantee. It depends on DU SOL’s server load and your specific paper settings. Do not rely on it as a backup plan — treat your first attempt as your only attempt.

2026 Pre-Exam Technical Checklist — Do This Before You Start

Our team has reviewed hundreds of portal crash complaints from DU SOL students in the 2024 and 2025 exam cycles. Almost every single problem could have been avoided with this checklist. Go through it at least 15 minutes before your exam:

Browser: Use Google Chrome (latest version) or Microsoft Edge. Do NOT use Safari, Opera Mini, or UC Browser. The MCQ portal’s JavaScript does not work properly on these.
Internet — The 2GB Data Rule: You need at least 2GB of free, stable 4G or 5G data available before you start. Low data or weak signal causes the exam to crash silently — the timer keeps running even though your answers are not saving.
One Network Only: Decide before starting — Wi-Fi OR Mobile Data. Never switch in the middle. If your Wi-Fi feels unstable, switch to mobile data before you begin. Going back to a stable connection is better than switching mid-exam.
Power / Charging: Keep your device plugged into a charger. When your battery drops below 20%, some phones show a low-battery notification or enable Power Saver mode — which can refresh background apps and crash your exam tab.
Clear Browser Cache: Go to Chrome Settings → Clear Browsing Data → Clear Cache and Cookies. Do this 10 minutes before the exam. This makes sure the MCQ scripts load fresh and don’t run old, broken cached versions.
Allow All Pop-ups for the Portal: In Chrome, go to Settings → Privacy → Site Settings → Pop-ups, and allow pop-ups for sol.du.ac.in. Some MCQ portal functions open in pop-up windows.
Close All Other Tabs: Before clicking Start Assessment, close every other tab. WhatsApp Web, YouTube, other sites — close them all. Even a silent background tab can cause your exam tab to freeze.
Disable Incoming Calls (Mobile Users): Go into “Do Not Disturb” mode. An incoming call on your phone will interrupt your data connection for those few seconds and can crash your active session.
Test Your Connection First: Open sol.du.ac.in, log in, and click around the portal for 2–3 minutes. If pages load quickly, your connection is ready. If they are slow, fix it before the timer starts.

The Screenshot Strategy — Your Only Proof if the Portal Fails

“I’ve personally guided hundreds of DU SOL students through exam portal crashes. In my experience, the ones who get a re-test are always the ones who have screenshots with a visible timestamp. Without screenshots, the university has no way to verify your claim — and most re-test requests get rejected. My rule is simple: take a screenshot every 5th question.”
— StudyDesire Team, based on student support logs from the May 2025 exam cycle

How to Take Screenshots the Right Way

After every 5th answer: Take a quick screenshot. This shows your progress and proves you were actively in the exam.
Show the timer: Make sure the screenshot includes the timer on the screen. This is time-stamped proof of where you were in the exam when the crash happened.
Screenshot the error: If the portal crashes, freezes, or shows an error message — take a screenshot of that error IMMEDIATELY before closing anything.
Save in Google Photos or Drive: Screenshots can get lost if your phone crashes. After the exam, instantly back them up to Google Photos or Drive.

If the Portal Completely Fails — What to Do Next

Email DU SOL Technical Support immediately.
Send an email to technicalsupport@sol-du.ac.in with your Roll Number, Paper Name, Date & Time of the exam, and attach your screenshots. The subject line should be: “MCQ Internal Assessment Technical Failure — [Your Roll Number]”
Visit North Campus if needed.
If your email is not answered within 48 hours, physically go to the DU SOL North Campus Student Support Cell with printed copies of your screenshots and a written complaint. In-person requests are handled faster.
Ask for a “Re-Test Request Form.”
Do not just say “the portal crashed.” Use the specific words: “I am requesting a re-test due to a technical failure on the assessment portal, and I have timestamped screenshot evidence.” This language gets you the right form faster.

Quick Reference: What to Do vs What NOT to Do

Situation	DO ✅	DON’T ❌
Screen goes white	Wait 10 seconds first	Immediately refresh / press F5
Internet drops mid-exam	Stay on same network, try reconnecting	Switch from Wi-Fi to Mobile Data
Need to look something up	Use a second device or printed notes	Open another tab in the same browser
Portal freezes	Screenshot first, then re-login within 3 minutes on same browser	Open Incognito tab or different browser
Timer about to run out	Submit whatever answers you have	Wait for “more time” — it will not come
Low battery warning	Plug in charger immediately without switching apps	Ignore it and keep going without charging
Incoming call on phone	Enable Do Not Disturb before exam starts	Accept the call — it breaks the data session

FAQ — Every Question DU SOL Students Ask About MCQ Assessments

These are the real questions we get from students every exam season. No generic answers — just straight facts:

❓ Can I re-login to DU SOL MCQ Internal Assessment if my session expires?

Generally, no — DU SOL does not officially allow a second login once your session has ended. However, if the portal crashed (not you clicking Submit), there is a narrow 3-minute window where your Session Token may still be active. Re-login on the same device and same browser within 180 seconds. Do not count on this — it is not guaranteed.

❓ What happens if the DU SOL MCQ portal auto-submits before I finish?

The portal has a server-side timer (usually 45 or 60 minutes). When it runs out, your current state — whatever answers are saved — is treated as your Final Submission. Unanswered questions are simply left blank. You will not get extra time. This is why you should answer the questions you know first and not spend too long on difficult ones.

❓ Does DU SOL treat partial answers as final if the timer runs out?

Yes. Whatever answers are saved on the server at the time of auto-submit are your final answers. There is no “incomplete submission” category. The system does not know you “ran out of time” — it only sees what answers it received before the timer ended.

❓ Does DU SOL MCQ portal track your IP address during the exam?

Yes, it does. Your IP address is part of your session identity. If your IP changes — for example, by switching from Wi-Fi to Mobile Data — the server registers this as a new session from a different location and logs you out as a security measure. This is not a bug; it is a built-in anti-cheating feature.

❓ Can I give DU SOL Internal Assessment MCQ on my smartphone?

Yes, but with precautions. Use Chrome on Android. Before starting: (1) Enable Do Not Disturb to block calls, (2) Disable Auto-Brightness changes, (3) Turn off Wi-Fi if you’re on Mobile Data so it doesn’t auto-switch, (4) Close all other apps. Laptop is still safer because it handles browser sessions more stably.

❓ What does “Response Already Submitted” mean in DU SOL portal?

This message appears when the portal has already recorded a submission for your Roll Number and that specific assessment. This happens when: (a) you actually submitted, (b) the timer auto-submitted your paper, or (c) a previous partial submission was registered due to a crash. If you believe it is a portal error, email technicalsupport@sol-du.ac.in immediately with your Roll Number and a screenshot.

❓ What is the minimum internet speed for DU SOL MCQ portal?

There is no officially published minimum speed. Based on our observations of student complaints, a stable 5 Mbps or higher connection works reliably. More important than speed is stability — a 10 Mbps connection that drops for 30 seconds is more dangerous than a consistent 3 Mbps connection. Use 4G or 5G mobile data if your Wi-Fi is unstable.

❓ What if I don’t click Submit — will my answers be saved automatically?

The DU SOL MCQ portal does periodically auto-save answers as you select them. However, the final confirmed submission only happens when you click Submit OR when the server-side timer forces an auto-submit. If the portal crashes before either of these, the answers saved in the last auto-save cycle are what the server has. This is why you should never leave the exam page — every second you are on the page, your answers are being recorded.

❓ Can I resume DU SOL MCQ test after a power cut?

Only if you come back within the 3-minute Session Token window, on the same device and same browser, and the server-side timer has not expired. If the timer ran out during the power cut, the auto-submit has already happened and you cannot resume. This is why having your device on charge is so critical — a power cut to a laptop on charge still leaves your laptop running.

❓ Is it safe to use a mobile hotspot during DU SOL MCQ exam?

It is safer than weak Wi-Fi, but only if you are also the person using that hotspot. The risk is that if someone else on the same hotspot makes heavy downloads, your bandwidth drops. Also, hotspot IPs can sometimes change if the host device’s network changes. Our recommendation: if possible, connect your exam device directly to a SIM card’s data — not through a hotspot.

❓ Should I clear browser cache before DU SOL MCQ exam?

Yes — always. Clear your browser cache and cookies about 10 minutes before the exam. Old cached files can conflict with the MCQ portal’s scripts and cause the page to load incorrectly or freeze at certain questions. In Chrome: Settings → More Tools → Clear Browsing Data → check “Cached images and files” + “Cookies” → Clear Data.

❓ What screenshots or proof do I need if DU SOL MCQ assessment crashes?

You need: (1) A screenshot of the error message on screen, (2) A screenshot showing the timer/time when the crash happened, (3) Screenshots of your last few saved answers, (4) A screenshot from your phone’s screen recording or gallery showing the timestamp. Email all of these to technicalsupport@sol-du.ac.in within 24 hours of the exam date.

❓ Can North Campus give me a re-test if DU SOL MCQ portal failed my exam?

In some cases, yes — but it requires formal evidence and a formal complaint process. Re-tests are not automatically given. You need to submit a written complaint with screenshot evidence to the DU SOL Student Support Cell at North Campus. They review it and decide. Students who have clear timestamped screenshots have the best chance. Without proof, re-test requests are almost always rejected.

Final Thoughts — Don’t Let a Technical Problem Cost You Your Marks

The DU SOL MCQ Internal Assessment is a digital exam, and digital exams come with digital risks. The good news is that 90% of these problems are completely avoidable if you prepare your device and internet 15 minutes before the exam starts.

To summarize everything on this page:

Re-login is usually not possible after submission or timer end — act before it happens, not after.
The 3-minute Session Token window is your only emergency option — same device, same browser, within 180 seconds.
Never switch networks mid-exam — your IP change looks like a security threat to the portal.
The auto-submit timer is real — it submits your answers whether you’re ready or not at 45/60 minutes.
Use 2GB of stable 4G/5G, Chrome or Edge, device on charge, cache cleared, all tabs closed.
Screenshots every 5 questions are your only legal evidence if the portal fails you.
