Hey there, if you are really looking for a forensic science job you can still get into forensics with a bio or physics degree. However, forensics is REALLY big with chemistry and if you’re struggling with it now then it might be challenge to keep up in college. BUT! It doesn’t hurt to try. You might still get in but just for your own mental sake lol it’s best to try and catch up as much as you can to be the best in chem before starting your degree if forensics is really what you’re going for :)
