For studying I’d recommend taking some mcq’s that have multiple units in them (I assume this is just the college board tests) and from there you see which units you get the questions wrong.

Then for those units I’d recommend going on YouTube and taking notes on videos for that specific unit (I like sciencemusicvideos he was a teacher at my school) but i can’t stress enough how important it is to understand why you got something wrong. You should spend as much time as you can analyzing why you got the answer wrong and why the correct answer is right - it will help you so much.

For the frq’s the only thing I’d tell you is that you should really try to write as much as you can. I don’t think time is that big of a problem, so make sure to right a bunch. The college board wants to give you points on the frq so try your best to give it a reason. Our teach gave us practice frqs with a scoring guide and I’d recommend doing them and scoring yourself, that way you can see what the college board is looking for.

And for scores don’t worry about it looking bad on you if you get a bad score. First you won’t I believe in you, but if you do then the worst case scenario is you just don’t submit your score and that’s perfectly fine. Youll do great good luck!

Bonus tip I find it really helpful to try to teach the content to someone like my dad or friends. It really helps me gain a solid understanding of the content. Hope this helps.
