i have been self study AP chem/physic since the beginning of the school yea and recently i started testing myself on frq since thats the only thing thats going to be on the exam this year. i started mid march and now its mid april. i have done around 6 years of past ap exam frq for each subject but I’m still not understanding it. i spend about 3-4 hours a day but for some reason its not clicking. I’m also doing calc ab but it is soo easy for me to understand like i know i will get a 5 but chem and physic is taking a beating on me. anything advice would help. thank you so much.
