Clearing the Cache
Your computer saves versions of webpages that you visit so that when you go back to that website, it will load faster. The problem is, that's not always helpful to a computer user. Clearing the cache gets rid of the saved versions and lets the computer load the most recent version. This would be helpful when, for example, your child's teacher adds some new content or information to Schoology. It's like clearing out the cobwebs or waking up after a power nap!
Tech support or your child's teacher may suggest clearing the cache when a webpage is taking too long to load or you get a message that the page cannot load.
