If the site refuses to open, start with the basics. Clear your browser cache and cookies — outdated cached data is one of the most common culprits. Try opening the platform in a different browser or switch from Wi-Fi to mobile data. If the page still doesn't appear, the problem might be on the server side, so waiting 10–15 minutes and trying again is a reasonable first step.
Sometimes question images or answer blocks render broken or don't show up at all. This usually happens when the browser is outdated or JavaScript is partially blocked. Make sure your browser is updated to the latest version and that no extensions are interfering with script execution. Disabling ad blockers temporarily can also help.
If you're entering the right email and password but still can't get in, try resetting your password through the recovery option. Also check whether caps lock is on or whether the email address has a trailing space. If the issue persists, try logging in from a different device to isolate whether it's a browser-specific problem.
A frozen test screen mid-session is frustrating, especially if progress is lost. This is often caused by a weak or unstable internet connection. Run a quick speed test — if latency is above 150 ms or bandwidth drops below 2 Mbps, the session may struggle. Switching to a wired connection or moving closer to your router usually resolves it.
If you complete a test but don't see results saved to your account, first check whether you were actually logged in before starting. Guest sessions typically don't save data. Log in, retake the test, and wait for the confirmation screen to fully load before closing the tab.
