Hello Aspirant

Computer Science is a subject that you can opt for if you have a science stream in 11th grade. And for the science stream, you will need at least 75% to 80% of minimum percentage. If you have it, you will be able to choose Computer Science as your 5th subject (along with Physics, Chemistry, Math/Biology, and English/or any other language that your school offers).

To be more clear and specific, kindly talk to your school teachers or administration about their requirements because every school has certain internal criteria for admission into different streams (Science. Commerce, or Humanities).

Hope this helps
