UIUC Appeal Help???

I stupidly chose bioengineering as my first choice, and got rejected. I’m deciding to appeal + pick a less competitive major, but I’m not sure what major to pick. I really want to go to medical school after undergrad.

I’m an instate student with a 29 composite ACT. My GPA is 4.5 weighted and 3.4 unweighted. I took 7 APs total, but I was supposed to have a more rigorous senior course load. My school is one of the top in Illinois/USA and many students from my school go to UIUC. I’m actually not sure why I didn’t get in considering I know many people with lower stats than me who got in. Anyway if you have any tips or ideas on what I should do/major in pLEASE HELP ME

Chemistry.
I have a slight lower stats than yours (27 and 4.5w), also in state. I got in in regular decision round and my essays are terrible, I mean really terrible. ( they are only about 100 words)

@Zpower99 ayy thanks. kinda hesitant on picking chem since i did pretty shitty on AP, but did really well on honors.
