How to monitor dropouts during an online exam

Check for brief connection drops before or during an online exam, learn what the results mean, and choose safe fixes without disrupting your test.

Your exam page freezes, a warning says you are offline, or your answer takes too long to save. It is hard to know whether your Wi-Fi dropped, the internet stalled, or the exam service itself had a problem.

The Connection Stability test measures response time, jitter, lost requests, and dropouts over a few minutes. Use it before the exam to check your connection, or during the exam only if your exam rules allow another tab or tool.

Check for connection dropouts safely

  1. Open the Connection Stability test before signing in to the exam. If you are already taking the exam, follow its rules first. Do not open another page or run a test if the instructions prohibit it.
  2. Use the same computer and network you plan to use for the exam. Close large downloads and uploads, and pause cloud backups so other traffic does not distort the result.
  3. Let the test run for a few minutes and watch for changes in response time, jitter, lost requests, or dropouts. A brief test gives you a snapshot, not a guarantee that the connection will stay steady for the whole exam.
  4. If a problem occurs and your exam rules permit it, note the time and what you saw. After you safely leave the exam, run the test again under similar conditions and compare the results.

The test sends requests to TooLab's server to measure the connection. It does not test the exam website's server, confirm whether an answer was submitted, or show what happened to exam data. If the exam freezes, use the exam provider's instructions for reconnecting and reporting the issue.

What the result means

Response time stays fairly steady and no requests are lost

Your connection reached the test server reliably during that run. This is a useful baseline, but it cannot rule out a later dropout or a problem between your device and the exam service. If the exam still froze, note the time and contact the exam provider.

Response time jumps or jitter increases

Response time is how long a test request takes to get a reply. Jitter is variation in that delay. A sudden rise can make a live session feel laggy, even if a speed test shows a good download rate. Compare the pattern with what you experienced, rather than treating one number as a pass or fail.

Lost requests or dropouts appear

The test did not receive replies to some requests. That points to an interruption somewhere along the route to the test server, but it does not prove that the exam connection failed at the same moment. A single lost request also does not tell you whether a saved answer was lost.

The test looks steady but the exam freezes

The issue may be specific to the exam service, browser, or device, or it may have ended before you ran the test. Record the time and exact message, then follow the exam provider's reporting process. Do not keep refreshing or restarting unless its instructions say to.

How to reduce the chance of a dropout

  1. Use a wired connection if available. Connect the computer directly to the router with Ethernet before the exam. If you must use Wi-Fi, stay near the router and avoid moving the computer during the test.
  2. Pause other network activity. Stop large downloads, video streams, file uploads, and cloud backups on your computer and other household devices. On Windows 11, check Settings › Network & internet for the active connection. On macOS, check System Settings › Wi-Fi to confirm you are on the intended network.
  3. Check whether the problem affects other devices. If several devices lose internet at once, the router or internet service may be involved. If only the exam computer has trouble, focus on its Wi-Fi connection, browser, or network adapter.
  4. Follow the exam provider's browser instructions. Use its recommended browser and close unrelated tabs if required. Do not disable exam security features, change permissions, or switch networks during a live exam unless the provider tells you to.
  5. Restart the router only when it is safe. A restart interrupts every device using that connection. Do it before the exam, not while an active session depends on the network.
  6. Contact the exam provider with useful details. Share the time of the interruption, the exact on-screen message, whether other devices were affected, and any permitted test results. Do not send passwords, exam answers, or private student information.

What a browser test can and cannot tell you

Connection Stability checks how your device reaches TooLab's server. Your exam service may use different servers or routes, so the two connections can behave differently. The test also cannot see the Wi-Fi signal strength in dBm. It measures how the connection responds, including delay and lost requests.
