It is really difficult to digest your query. Many students drop years to fight medical entrance tests and you are about to complete your course but not finding it good for yourself. Strange!
Yes you can pursue MBA but before that, I would like to suggest you to complete your MBBS and internship honestly.
Then do practice for a while and then pursue MBA.
Then you will be able to own your own hospital as you will be having you hard earn money with you, your medical related knowledge and finally management knowledge.
If you do not want to be in medical field at all, then you need to decide the field of your interest in which you want to have your career. Then only decide for course. Merely doing MBA does not guarantee a bright future.
If you want to go for software kind of job, then go for some short term relevant certification courses and get a job.
If you want to be in pharmacy related career, you can pursue B-pharma and D-Pharma.
There are lots of options you can have, the only thing which is must required is your stiff decision and focus.
