pre med.... should i apply for cs

hello, im a pre med student. gave mdcat and boom, life was f*cked. all my life i was a grade A* student, nerd and no friends. my whole life was centered around academic validation, but i failed the biggest exam.

so, now my question is, guys, should i apply for computer science? i know im hardworking and if i actually try, i can do it as well. but, on the other hand, cs is getting really saturated and i don't want to be average and mediocre.

given the circumstances, i have two options; either go for cs or do bba. so, please give me suggestions what program should i apply for

thanksss
