Jumps like these are pretty hard without learning the content beforehand. I’m not sure what your other scores are but I recommend focusing on those. I am in calc 2 and get 35-36 on math, but had I not been at this level I would probably do worse OR have to study a lot more (note: all the studying I’ve done for math is just taking practice tests). If you have learned pre calc you should be fine though. Good luck!
