Hello,
First of all, the one and only route to become Doctor is MBBS Degree.
Secondly, NEET is the entrance exam conducted for admission into medical course, other institutes like AIIMS, JIPMER conducts their own entrance exam regarding this process. The common thread that binds the eligibility criteria for medical course in all these aforementioned exams, specifically MBBS Degree to say, is passed 10+2 from a science stream. Of course, there are subjects combinations and aggregate for different category as well.
Hope, this clears all doubt.
