Hello aspirant,

Since you're studying in 11th class with pure science group, so after the completion of 12th only, you can pursue your career with BSC Physics. To pursue this course, make sure you have completed your 10th and 12th from a valid recognized board with a minimum percentile of 60% or more. Admissions will be based on either through merit based or through entrance level. You can only pursue BSC Physics once you complete Intermediate.

Hope, this answer helps you.
