Anil, your code should be ideally 05 because if you have completed your 12th and are pursuing your Bachelor's degree, your code is no more 02. Now that being said, you do not need to submit your B.Sc certificate. The documents that you need for NEET during Document Verification are:

• 8 passport size photographs
• 10th marks sheet
• 12th marks sheet
• Valid Id proof
• NEET 2020 admit card
• NEET 2020 Rank card
• Provisional Allottment Letter
• Category Certificate if applicable
• Domicile Certificate if applicable
• PWD Certificate if applicable

They will need your 12th documents more importantly than your B.Sc documents.
