Tips to Improve Computer Performance for Web Assessment

Simple steps to make sure the assessment runs smoothly

Lexplore’s web assessment uses the computer’s webcam together with eye-tracking.
For best results, the computer needs to maintain a high and stable frame rate during the session.

Here’s what you can do before starting:

✅ Close other video apps like Zoom or Teams – they can block or slow down the camera.

✅ Close extra programs and tabs – keep only the assessment open.

✅ Use good lighting – make sure the student’s face is well lit.

✅ Plug in the laptop and use “Best Performance” mode instead of battery saver.

✅ Restart the computer to start fresh.

✅ Update your browser (latest Safari on Mac, Chrome or Edge).

 

If performance is too low – try this:

  • Try Chrome or Edge if you are using Safari.

  • Check the camera settings with your IT department. The webcam may be set to a high resolution (for example 1080p), which is unnecessarily demanding for the Web Assessment. Lowering it (for example to 720p) can improve performance.

  • Try on a newer computer if one is available – it helps determine whether the issue is hardware-related.
