low gpa already :-(

hi! im new to this subreddit, but i wanted to tall about my low gpa and get some advice so i can start planning ahead.

i go to uc berkeley, currently a integrative biology major and already have a 2.9 GPA. im in my second year i got a C on an intro bio course, chem 1, and precalculus in terms of science or stem gpa.

this semester ive completely changed my study habits but in the back of my mind theres this lingering thought that im not cut out to be in stem or PA.

im not too worried about PCE, as i got my cna license in highschool and started on that over the summer.

any advice?
