Does anyone have any resources to study for exponential growth and decay problems, most study guides skimp over it, and I also need help with interpreting graphs, for example I can’t tell when a certain portion of a graph is decreasing or increasing based of if it says graph of f, f’, or f’’, it always confuses me! Lastly, does sketching slope fields need to be perfect? My teacher strictly told us that when we draw the line it can’t touch any slopes, but on solved frq problems and answer keys it seems very sloppy but still gets full points. So any tips on how to appropriately draw slope field lines would be greatly appreciated!

I’m in high school taking calculus ab, while I feel like I slacked off my first semester with poor studying, I have done much better this second semester. However our teacher has given us mock exams for the actual final, and so far for the MCQ portion I narrowly passed with a 3 despite how hard I studied, I’m worried if I can recover and study hard enough to get at least a 4 or 5 for the real deal.
