Why Choose Science Stream in Class 11?

You must’ve heard the famous quote by Edward Teller, “The Science of Today is the Technology of Tomorrow.” It simply explains how innovative discoveries in the present lead to a better life in the future.

Choosing a Science stream provides students amazing research opportunities and brings them closer to innovative technologies. Candidates get to study subjects like Physics and Chemistry to gain an in-depth understanding of the universe's physical, chemical, and biological aspects. Plus, it also helps with their problem-solving and analytical abilities. 

The Science stream consists of scientific theories and practical concepts that help polish their knowledge regarding natural and artificial processes in the world. As a result, students qualified in the science stream have a wide range of career opportunities, including Space research, Computer Science, Biotechnology, Nanotechnology, Pharmaceuticals,  Forensic Science, Mechanical Engineering, etc.

What are the Science Subjects in Class 11th?

When it comes to the 11th science subjects list, the Science stream is divided into two sub-branches based on the third subject that students choose as per their interest:

  • Medical – Physics, Chemistry, Biology, English, Optional Subject

  • Non-Medical – Physics, Chemistry, Maths, English, Optional Subject

With Physics and Chemistry as common subjects in both disciplines, the main difference is whether you choose Mathematics or Biology. Biology is chosen by those who want to pursue a career in Medical Sciences, while Math opens the door to a career in fields like Engineering, Architecture, etc. Aside from these subjects, students must additionally select English or Hindi.
