Dear Sushant, yes you can change your MBBS marks in NEET PG form during the correction window. The correction window will be provided during last week of December. However, there are only few details which can be edited.

These details can't be altered-

• Name
• Mobile number
• Email address
• Testing City
• Gender
• Date of Birth
• Nationality
• Category of Candidate

All the best

Hope this helps
