Alternate options other than MBBS?
You have quite a few optons like if you feel research is what you want to do after your studies then – Msc or Engineering in fields like biochemistry, biotechnology, biomedical, agriculutre, microbiology, environment science etc.,
Other options like physiotheraphy and related studies, nursing, audiology, lab technology, a degree in nutrition and dietics could also be a great choice.
Pharmacy could be another fine option, along with dental science, veterinary science, dairy science to name a few other alternatives.
Quite a few options out there, and if you are still confused with so many, what you can do is first jot down a few that interests you and then check out what kind of courses is involved in each of these fields, then see what kind of job (the day-to-day work) that would be involved in these.
This will give you a good idea of what exactly they are and then you can shortlist the ones that best matches your interests and skill levels.
