ap physics itself is very hard. mr mat will go through the lesson and you probably won’t understand anything except maybe a formula or two so make sure you go on organic chem tutor on youtube to fully understand the lesson. i had him when we were virtual so i had pretty much no homework except for the occasional lab or worksheet that needed to be turned in on google classroom but he grades for completion. make sure you understand why the formula is the way it is because the class is very conceptual and you will have to move around equations or even set them to 0 because of a specific variable. as long as you prepare for the quizzes and tests, you will do fine
