When you try take a Mock Test for ISTQB , QTP or any other topic, at times you may be shown a Time Out Error.
The test component uses session ids to keep track of timing during a test.
The problem manifests chiefly when you have already taken the test once and again want to retake the test for practice.
We have made coding adjustments such that the problem will not occur to most users.
Though, "time out error" may be shown for certain browsers
Here are the resolutions you may try -
Try accessing the site from a different browser. Ex. If you are currently accessing the site via Mozilla Firefox , and you get the error, try accessing the site via Chrome or IE.
Clear cache history in your browser. Ex. If you are accessing the site via Firefox and you see time out error , go to Options and select "Clear Recent History".
Try accessing the test after a break of 15 minutes after which the session id will expire.
Hope it helps
