Should i drop out of college if i'm scoring low in a useless degree?

i'm currently doing a bsc degree in local bad tier college. All exams went okay except for physics(45/70). Also my stupid brain wrote 3 line answers in 8 marks questions in all papers(including okay ones). i'm cooked! Didn't know answers of 2 long answers in physics(8 masks each.) I feel like i should just drop out and try into different college(maybe bca) and study from the start. This degree is useless anyway.
