If you want to go for the course of BTech in Pharmaceutical Technology then most of the institute will ask for Physics, Chemistry and Mathematics as subject combination in 10+2. Now as per the  NEP 2020, if the student have Mathematics or Physics any one subject in 10+2 then they are eligible for the BTech course. Now this rule isn't implemented by all the institutes in India. So before filing up for admission, you should visit the official website of the college and understand the eligibility criterion.
