Also - a typical AP Chem course is 5 40 minutes periods per week for 18 week (I assume you won’t do what’s in the lab periods), about 120 hours. In reality, about 80-90 is probably teaching material. Over 4 months, that’s spending 45 minutes a day, every day, or an hour every weekday. If you’re a quick learner, maybe less.
It’s certainly possible, but it takes time and dedication. You’re not going to learn it in 10 minutes a day.
