Honestly dear !! It's great that you are planning to begin your MBBS preparation once again, but as you know in the final two semesters of B.Pharmacy there are subjects like Biostatistics, Project Work, Practice school etc. which would consume a profound time of yours. But yes after you qualify NEET and take admission they will not allow you to pursue two regular courses at the same time, you need to leave any of them. If you take admission in MBBS then as per your Institute norms you might have to leave the B.Pharm course. It is better not to leave that after three years, complete it, get your registration and sit for the campus interview for a better job next year.

Good luck!!!!
