Psych or Macro/Micro.

I’ve heard the APs in the title can be done with just a quick read, in under a week each.
If I read it now, take practice exams and get everything done before school starts, do you think I’ll forget everything by the time the exam comes? I’ll probably reread it a week or two before it starts again but I’m not a strong memorizer.
Would it be better to reread it week by week or should I be good to go a week or two prior to the exam?</p>

The reason why I want to learn it now is because I want to self-study the sciences during the school year. I’ll be going into grade 11 and am planning on taking AP Bio/Chem. Will many grade 11 bio/chem concepts be included in the AP topics? Is it a bad idea to self-study these two without completing the grade 12 courses?</p>

My school does not offer any AP courses, p.s.</p>

Also if anyone could tell me how Macro and Micro differ, it would be great. I learned a bit of economics last year in my business class (a highly qualified teacher, taught at Harvard) and I’m not sure which topic my knowledge would be better suited for. Should I just take them both? do they overlap a lot?</p>

Thanks a bunch,</p>

Macro is about the bigger picture, and Micro is more detailed.</p>

Macro is the economy in a nation and in between nations, and micro is the economy on a business scale.</p>
