CBSE 12th

Can I know your stream, interest and marks?

Well, you can become a doctor by following these steps:
Step 1-Learn PCB NCERT's line to line. Treat every line as an MCQ. Practice physics numerical problems.
Step 2-Crack PMT/NEET /AIIMS/JIPMER exam with good marks and study MBBS for 5 years.
Step 3-Do your PG as MD/MS for 3 or 2 years.
Step 4-Clear UPSC medical entrance exam, apply for the army, open your own clinic and get your white coat.

As you are through with the GDPI Process and the results are going to be out next week itself, do not overthink about the chances and wait for the list to be out. As per your scores, you have a decent chance of getting selected. But then again it actually depends on the way your GDPI was done, if it was good then you have a good chance.
Good luck.
