This class makes you work for the A, especially seeing that it is an intro class. I had limited background from the end of Physics 1B regarding circuits.... but the class starts from the gun (no real intros into circuits/solving circuit problems). The first 4 weeks are a lot of work. The last 6 weeks are not a lot of work, but get conceptually more difficult.
IF YOU LEARN ONE THING FROM THIS REVIEW, when you are coding your robocar, code a function that allows the car wheels to move backward. i.e. you pass in left and right speeds and if one is negative it switches the direction pin for that wheel. it won't make as much sense now but you can literally code the car in one class period with this.
Lectures aren't very helpful, I recommend going to the lecture for the quiz and then learning the stuff through the Organic Chemistry Tutor/other youtube videos.
