My grades are dropping this year?

Well, my opinion is that you're doing great! As and Bs are superb. But to you those Bs aren't, and I understand as a former student in chemistry AND physics *shudders* and my physics cl JUST ended. Don't worry, most of us aren't very science related, so if you are having problems, I'd get extra help, like I know my school offers tutors inside of school, outside of school, peers, and all of our teachers are willing to help. Plus, most parents are there for you :) but since you don't have any issues with anything but you can't apply the concepts to the problems, I think the major solution would be to practice, practice, practice, or get help on example problems. I know that's what I did, and before I did anything to resolve my non-understanding of the material of one of my cles, my first test I got a 68%, not good. So I went to get help and my final grade was a 98% in that cl (and I retook the test, with over a 90...I forgot the precise grade haha). I'm suggesting to get your grades back up is to ask for any extra credit, and if you can do ANY retakes, (take any chance you have) and if worse comes to worse maybe switch to a different cl if you're able to (or in the beginning of the quarter, trimester, semester, etc) or if your school offers it a p/fail option (where your grade for that cl is not recorded) and you can retake the class next year or over the summer and try to get a "super-awesome" grade. That's all I have! And sorry this is so long :) hope this helps and didn't waste your time!
