How do I auto-refresh a tab (just that tab) without downloading any extension or anything? I have a chrome OS. I really need to do this, but I don't know how. Also, if you're going to answer this question, please give me simple instructions. I don't know a lot about computers so if the instructions aren't simple, I probably won't understand.

You can do it in, I assume, your Google Chrome tabs. It does require some programming type activities, at least the way I know of. Rather than steal credit from another, here is the link to the page where I found an answer for you.
Automatically reload page in Chrome without plugin
If you do not feel comfortable doing that, a plugin is your only way to go. Short of building a machine to hit the f5 key over and over again.
