Choosing a stream of subjects for Class 11 and 12 is the first of many big career decisions you will be making in your life. After having studied a variety of subjects for your entire school career, the time has come to select a specific stream that suits your interests, capabilities and career goals.
Even if you haven’t identified any particular career goal so far, don’t worry, there is still plenty of time for that. Selecting a stream is comparatively easier than selecting a career, but making a careful choice is still important as your stream can influence your career.
There are 3 main streams available after Class 10, namely Science, Commerce and Humanities/Arts, and each stream has a distinct methodology, choice of subjects and career options. While Science is based on the theory and application of scientific concepts, Commerce is focused on trade and business, and Humanities is based on the liberal arts.

Science Stream Subjects after Class 10th
The science stream is further divided into 2 branches, namely medical (PCB) and non-medical (PCM) science stream.
The difference between the two lies in the choice of the third subject. While Physics and Chemistry are compulsory for both, the medical stream offers Biology as the 3rd compulsory subject, and the non-medical stream offers Mathematics. English is common to all streams and students can take up any optional subject to meet a total of 5 subjects.
Here is a detailed look into the compulsory subjects in the Science stream:
Physics is among the oldest academic fields in the world and is the science of matter, motion, energy, and force. It focuses on understanding how the universe behaves. Advances in the field of physics enable advancements in technologies, such as the study of electromagnetism, thermodynamics, mechanics, nuclear physics and solid-state physics.
Studying physics at Class 11-12 level will help you develop observational, analytical, investigatory and decision making skills, along with conceptual understanding, creative thinking, and problem-solving skills.
Examples of a few topics you will study are:
- Laws of Motion
- Electromagnetic Waves
- Electronic Devices
After studying physics there are a variety of career options available, including working as a physicist, astronaut, data scientist, technician, and engineer.

Everything in the universe is made out of atoms and matter, and the study of Chemistry is based on the study of the composition, properties, and structure of matter, including atomic structure and the changes influenced by chemical reactions.
New areas in chemistry, such as synthetic materials, natural resources, biomolecules, and industrial chemistry are also included in the course at the Class 11-12 level, ensuring that you get a thorough understanding of Chemistry fundamentals and contemporary developments. Practical lab experiments further serve to support your theoretical studies.
Examples of topics you will study are:
- Chemical Bonding and Molecular Structure
- Chemical Thermodynamics
- Organic Chemistry
- Chemical Kinetics
- Surface Chemistry
Career options after studying chemistry include working in research, pharmaceuticals, healthcare as lab scientists, chemical engineers, biochemists, flavour chemists, analytical chemists, etc.

The term ‘Biology’ is derived from the Greek language, with ‘bios’ meaning life and ‘logos’ meaning study, literally translating into the study of life forms. And that’s exactly what biology is. Biology studies living organisms – plants and animals – including facets such as their physical structures, physiological mechanisms, chemical processes, molecular interactions, and development and evolution.
The subject of Biology at the Class 11-12 level focuses on providing a firm conceptual basis while also connecting the study of the subject with real-life technology, environment, agriculture, health, and industry.
Examples of topics you will study are:
- Structural Organisation in Plants and Animals
- Cell: Structure and Function
- Plant Physiology
- Human Physiology
- Genetics and Evolution
- Biotechnology and its Applications
Career opportunities after studying Biology are immense, including the most popular path of Medicine, whether MBBS or Ayurveda or Homeopathy. Apart from medicine, you can pursue a variety of career paths such as biotechnology, dentistry, veterinary sciences, pharmaceuticals, botany, zoology, marine biology, genetics, bioinformatics, microbiology, and more.

At a Class 11-12 level, you would learn about the principles of underlying processes and skills, identify the flow of reason while solving a problem or proving a result, and learn how to apply acquired skills to solve problems by more than one method. If you pursue the Medical (PCB) stream, you can also take on Mathematics as an optional subject.
Examples of topics you will study are:
- Mathematical Reasoning
- Linear Programming
- Vectors and Three-Dimensional Geometry
Studying Mathematics in Class 11-12 opens up a variety of career options, including those in the field of commerce, if you decide to change your mind about a career in the sciences. Career options include engineering, computer science, insurance, statistics, economics, banking, accountancy, etc.
