not able to manage preparation with college ?

That's Great !! On somedays you may not be able to much and that's Alright.
On weekdays, give yourself with some targets from all 3 sections and try completing them, and on Weekends, have Long dedicated study hours and give some extra time for your prep and that would help balance your college and prep ig. Happy Learning !!

that's totally fine when u are consistent, ur discipline matters than the quantity
