So I think that the a level AQA endoresed textbook by jim breithaupt is ABSOLUTELY terrible. It's just full of useless, irrelevant information.Also, the CGP revision guide is far too brief for me, and it contains some uneeded information. So I don't know what to take notes from anymore. My only other options are online revision guides ( if you have any, can you link/name them?) and Youtube videos. I understand that the main thing is practice Qs, but I also want to understand the content
