If you want to be a Doctor then you have to select science stream after your 10th with Physics, Chemistry and Biology/Biotechnology as the subjects compulsorily. Apart from this you have to clear an entrance examination namely NEET and on that basis you will be offered admission to the medical courses such as:

• MBBS
• BDS
• BAMS
• BHMS

& many other courses.
