I started taking my first chemistry class this year in high school (sophomore) and I feel extremely lost due to a mixture of the fact my teacher assumes everyone took physical science their first year of high school (even though every sophomore in the class took biology freshmen year because that is the prerequisite to chemistry at our school) and her teachings are all based on the assumption we have already covered physical science - and also the fact that she just isn't a very good teacher... (as in giving us a lab without giving us the procedures and saying the next day "Oh! I see I forgot to give you the procedures! No wonder you were all lost!). Almost the entire class is hovering around the C range but I'm maintaining an A just for the fact I won't let myself fall below that. Even though I'm maintaining a decent grade, I feel like I'm missing big concepts and ideas that I should otherwise have. When I hit college, will they base every lecture off of high school chemistry? Or will they essentially start fresh? Its our school's policy to not allow kids to switch teachers which would otherwise be my desired option and I won't let it bother me to much if I'm not robbing my potential in college. If any of you have any insight on this - I would appreciate it!
