How to fill in CAT form

I have two degrees ongoing
1. Btech-CS (last year)
2. BS in Data Science from IITM (in Diploma level)

So how should I fill it in CAT registration form...is it dual degree or is it just my preference to keep one as main? Are there any specific extra points also for this?


Wasn't really sure and I filled just the Btech in XLRI forms, but want to be clear now
