Other informative sites for 5A and 3A?

I know about Miguel Correa’s page for 5A and YYE for 5A but are there any other good places to look for 3A or 5A?

My roommate wants to get into 3A and the resources are very limiting and 5A is a little bit more abundant but I would like more choices that just yotricks, YYE or Miggy’s youtube channel.
