How Do I Empty My Browser Cache?

Your internet browser's cache stores certain website data to make future visits more efficient - faster load times, saved content, etc. Occasionally, however, your cache can prevent you from seeing updated content, or cause functional problems (e.g. repeating item sets, failure to record sessions, etc.), when stored content conflicts with live content. You can fix many browser problems simply by clearing your cache. The instructions to do so are listed below. After clearing your cache, reboot the device and test your student session.

Note: Clearing the browser cache may delete your saved passwords and website history.
