Having now monitored a number of Blackboard tests, we’ve discovered a simple step that can help students (and faculty!) avoid problems: clearing your browser’s cache. This sounds much more difficult than it really is. You only have to do it once (though it’s not a bad idea to clean things out periodically). Below you will find instructions (including screenshots) on how to clear cache in four popular browsers used at OC. Click the link corresponding to the browser you use to jump to instructions for that browser.
