Dear student,

since you had RT in biology, if you are passed in the subject now then you are eligible for BSc , however it depends on the branch of BSc that you are going to choose since specific courses have their own eligibility criteria where they may need certain percentage in a specific subjects, so its better to choose a course in which you meet the eligibility criteria.

If you have passed your 12th, then you can go for the course of BSc for most of the universities/colleges. But there are some institutes can keep a condition that the student must pass all the subjects. So while applying just check it that the college you are applying don't have any condition like this.
