It would help if you could clarify further. What do you mean by 2 years group marks?

If you are asking about how to fill the relevant sections of the NEET application form as someone who has completed their Class 12 as an Intermediate student, then please note the following:

1. Select your Qualifying Exam Code as 03.
2. Select your year of passing Class 12/Intermediate from the drop-down menu.
3. Enter the percentage obtained in your final exam in Class12/Intermediate.
4. Enter Roll Number in Class 12/Intermediate as given in your Pass Certificate.

In the next section, where they have asked for ‘Details of Marks of Qualifying Exam’, write the maximum marks out of which the English, Physics, Chemistry and Biology papers were conducted in your Class 12/Intermediate final exam. If it was out of 100 (inclusive of theory and practicals), then write 100 in each of the four fields. If it was out of 150, then write 150. Now in the corresponding fields, under ‘Marks Obtained’, write the marks you obtained in each of these subjects in your Class 12/Intermediate.

Good Luck!!!
