im from maharashtra state board.In our hsc certificate only total marks are given not differentiated on theory and practical.What are the marks for eligiblity in neet for sc candidate?? im confused

Hi , in order to get eligible to write in NEET UG exam you need to score a minimum of 40% as per your mentioned category, which is an aggregate marks of physics , chemistry and biology together in your 10+2 with physics chemistry biology and English as your core subjects. And you should be a minimum of 17 years as on 31 December 2020. Talking about marks you need to go for total marks for calculating percentage and not theory or practical marks alone.
Hope this helps
