Connection planning for a remote exam

A connection that works for ordinary browsing can still stutter during a timed remote exam. Video, screen sharing, or proctoring may need a steady connection, and a brief dropout can interrupt your session.

Check the exam provider’s technical requirements first, then test the same computer, room, and network you plan to use on exam day. TooLab’s Speed Test checks download speed, upload speed, ping, and jitter. The Connection Stability test can help reveal brief interruptions that a short speed test might miss.

Check your connection before exam day

1. Read the exam provider’s instructions for minimum speeds, supported browsers, and any camera or screen-sharing requirements. Open the Speed Test on the computer and network you will use for the exam.
2. Run the test once when the network is quiet. Note the download and upload speeds, ping, and jitter. Upload speed matters when your camera or screen is sending video to the exam service.
3. Run the Connection Stability test for a few minutes, ideally while using the network as you expect to on exam day. Look for lost requests or dropouts, not just the average response time.
4. If your connection may be busy during the exam, use the Bufferbloat Test to compare delay while data is downloading or uploading with the delay when the connection is idle.
5. Repeat the checks at the time of day your exam is scheduled. If you plan to use Wi-Fi, test in the room where you will sit. If possible, compare it with Ethernet or another reliable connection.

Keep the results and note the time, connection type, and whether other people were using the network. This helps you compare changes and explain a problem to your provider or exam support team.

What the results mean

Speed meets the provider’s requirement, and the connection stays steady

This is a good sign for your setup, but it cannot guarantee that the exam service will be available or that your connection will never drop. Use the same network and room on exam day, and avoid starting large downloads or backups during the session.

Download speed is good, but upload speed is low

Downloads help load pages and receive video. Uploads carry your camera feed and other data back to the service. If the provider lists a separate upload requirement, compare your result with that figure. Pause file syncing, cloud backups, and other uploads, then test again.

Ping or jitter is high, or the stability test shows drops

Ping is the time it takes a request to get a response. Jitter is the amount that response time changes. High or uneven results can make live video and interactive exam pages feel delayed, even when the headline download speed looks fine. Repeat the test on Ethernet or closer to the router, then compare.

Delay rises sharply during a download or upload

This can point to bufferbloat, which means a busy connection is building a queue and delaying other traffic. The Bufferbloat Test gives a grade from A+ to F. A poor grade under load does not by itself mean you will lose the connection, but it can explain lag when someone else is using the network heavily.

Improve the connection you plan to use

1. Use Ethernet if you can. A direct cable to the router avoids many Wi-Fi signal problems. If you need Wi-Fi, take the exam near the router and avoid putting it behind furniture or inside a cabinet.
2. Pause competing traffic. Ask others at home to avoid streaming, gaming downloads, and large uploads during the exam. Pause cloud syncing and software updates on your computer, then rerun the stability test.
3. Check your network connection settings. On Windows 11, open Settings › Network & internet and check whether you are connected through Wi-Fi or Ethernet. On macOS, open System Settings › Network and select the active connection. Reconnect to the intended network if the computer has joined a weaker one.
4. Restart the router before the exam, not during it. If your connection has been unstable, restart the router well before your scheduled start, wait for it to reconnect, and run the tests again. Avoid changing unfamiliar router settings just before an exam.
5. Prepare a backup connection. If your provider allows it, identify a phone hotspot or another network you could switch to. Check that the backup has usable coverage where you will sit, and confirm how to reconnect without closing the exam. Mobile data can be variable, so do not assume it will work without testing.
6. Check the computer’s power and wireless settings. Keep a laptop plugged in if possible. If Wi-Fi keeps disconnecting, install operating-system updates and restart before exam day. Do not install updates or drivers just before the session if you cannot test the computer again afterward.

Make a simple exam-day plan

Test at least once before exam day, then check the connection again shortly before the session. Close apps that use the camera, microphone, or network, and make sure your exam browser can access any required devices. If the exam requires a specific connection or forbids switching networks, follow its instructions rather than relying on a hotspot.

Save the exam provider’s support contact and instructions for reconnecting before you begin. If a dropout happens, follow the provider’s recovery steps first, and avoid refreshing or closing the exam unless its instructions tell you to.

Speed tests exchange test data with our server to measure the connection, so run them before the exam rather than during a timed session.
