Hello Yaswanth,
For you aggregate percentage in the special round, you have to consider the following subjects -
1. Mathematics
2. Physics
3. One subject out of Chemistry/Biology/Biotech/Technical vocational subject
4. One language
5. One other subject
Add all the scores, divide them by the maximum marks and multiply by 100 to get your aggregate percentage.
All the Best!
