    Welcome to PF!

    Hi tyrizzle! Welcome to PF! :smile:

    Sorry, but maths obviously isn't your thing …

    Some students find questions like this easy, and they can go into a "fast" class where things aren't explained so much.

    Other students need a "slower" class, where the teacher has time to go over things more carefully.

    Students in the "slower" class should eventually reach the same level, but a student who wrongly goes into the "fast" class won't.

    To do good physics, you need a good background in maths. Now is the time to get it, and it's best not to get into a class that will cause you a lot of extra work and worry, and will pull all your grades down. :smile:

    Don't worry about starting low. You have 4 years. Taking a couple of remedial math courses is no big deal. In a year, you'll be taking Calculus, so don't worry about it.
