I haven’t studied properly during my MBBS and got very average scores every year. Can I get a decent rank in NEET PG 2021 if I studied seriously during my internship?

Yes, good effort of 6–8 months is enough to make a difference. Here are my suggestions-

1. Start with positive intent and tell yourself that if you work hard you will be able to do it. Remember the quote, hardwork can beat talent, if the talent doesnot work.
2. Take guidance. At your preparation level regular courses is suggested.
3. Work on three things- content building- making notes, revision and exam skills- giving tests.
