Neurology as a career?

MBBS and Engineering are completely different areas of subjects. Don't try to sail on 2 boats at a time. Choose what you are most interested in either Engineering or MBBS. Its only a myth that MBBS is too costly unless you opt for private colleges where the fees is too high in comparison with Engineering. MBBS fees at govt colleges will be 5k-10k compared to private colleges where they charge lakhs. So work hard and try to get into Govt colleges.

Neurology is a very good area of study. For your information Final year MBBS isn't easy to crack(i heard this from my friends who are did their MBBS)

I feel you will have a clarity on everything by the time you complete your 12. Don't be too confused. Get interacted with your seniors and lecturers well. They will guide you

I appreciate Ur ambition your optional subject is math as alternative of failure in doctorate first let me tell you clearly you yourself is not confident that's y you HV taken math as alternative besides all this you must obtain more than 70 percent marks in 10th and 12th then you are eligible 4 entrance in every entrance test during these two years you HV to restrict yourself up to a room leaving all entertainment aside then entrance will decide your fate if you will get selected then you don't have to pay a single penny but expenditure of books mess u have to bear but this is minor doesn't matter you have not to choose neurology in final year but after completing mbbs and completing house job which is 4 one year then you HV to apply 4 either MD r M.S if Neuronsurgeon then M.S master of surgery if M.D master of drugs in neurology but after completing mbbs you have to apply 4 this and then face one more entrance test for Ur specialization in neurology either as surgeon r as id drugs of neurology best of luck
