Science Subjects in Class 11th: A Detailed Handbook


Are you preparing for class 10th board exams? Are you surrounded by questions like which stream you should choose? Do you know what science subjects you can opt-in class 11th? Or what are the job opportunities in the different chosen fields? But to answer all these queries you need to self-interrogate and unlock the question box!

You should do an in-depth analysis of your strengths and weaknesses and choose a combination of subjects that suits your interests and professional goals. And for that, you need to have an understanding of everything related to class 11th science subjects.

According to the new National Education Policy (NEP), there are no streams anymore. Students, parents, professionals are all also being encouraged to discontinue the usage of the word ‘stream’. However, since most of us are still accustomed to this word and not familiar with any other new word, we may use it across this article but as rarely as possible.

Come along.

What are the science subjects in class 11th?

This science stream is divided into 2 branches:

  • Medical: Physics, Chemistry, Biology, English, Any optional subject of your choice
  • Non-Medical: Physics, Chemistry, Mathematics, English, Any optional subject of your choice


Physics and Chemistry are common in both disciplines and the main difference is whether you choose Mathematics (PCM) or Biology (PCB). However, students sometimes go with your combination of both (PCMB), choosing to study both Mathematics and Biology instead of another optional subject.

Why choose science?

From great research opportunities to innovative opportunities and technologies, science offers a flexible work environment, full of expertise, and prospects that you can explore.
