Students preparing to take on their 10th standard board exams can find themselves overwhelmed with the wide range of options available to them. Deciding whether to take the popular route or to explore something less traveled is a tough decision, and one needs to carefully assess their skillset and interests before choosing a stream that aligns with their career goals. 

Of the three streams available, Commerce and Arts offer a variety of approaches and job opportunities, but in this article we will focus on the Science stream. By understanding why this particular stream has been chosen, students can make an informed decision about which path best suits their individual needs. It is important for students to undertake thoughtful self-assessment in order to determine which course of action allows them the best chance of success in the future.

Why Should You Study Science?

 Subjects in the Science stream include elements of both scientific ideas and practical notions. These topics not only provide students with an in-depth understanding of the physical, chemical, and biological components of the cosmos, but they also provide students with analytical and problem-solving skills. The topics also aid in comprehending the effects of natural and man-made processes on the planet. As a result, students who choose the Science track have a diverse range of professional options. Some of the various professional options you can take after studying Science subjects include bioinformatics, dental science, space exploration, computer science, metallurgy, pharmaceuticals, biotechnology, nanotechnology, mechanical engineering, and forensic science.

Subjects in the Science Stream: Overview

The Science Stream is divided into two branches: non-medical (PCM) and medical (PCM) (PCB). With Physics and Chemistry as shared subjects, the distinction between the two divisions is in the third subject chosen. While Math is chosen by students who want to pursue careers in fields such as, but not limited to, Engineering, Architecture, and Commercial Piloting, Biology is chosen by those who want to pursue a career in Medical Science. Aside from the topics listed above, students must additionally study English or Hindi, as well as an elective subject. Popular electives include Informatics Practice, Physical Education, Computer Sciences, Engineering Drawing, Economics, Home Science, and Psychology. The following is a full list of Science stream subjects:

Mathematics, generally known as the study of numbers, conveys knowledge and clarifies conceptions of amount, structure, and space. This Science stream subject teaches you to identify the flow of reason while solving a problem, comprehend the principles of underlying skills and procedures, and justify the results using various approaches. This course covers topics such as calculus, mathematical reasoning, algebra, probability, and linear programming.



Biology is one of the most well-known Science courses, involving the study of all living species. It teaches a wide range of topics about organisms, including physiological systems, molecular interactions, physical structures, evolution, and development. Cell Structure and Functions, Structural Organization in Plants and Animals, Human Physiology, and Plant Physiology are some of the subjects addressed in this course.



Another popular Science stream subject is Computer Science, which is particularly popular among students who want to study Engineering or work in technical fields. In class 11 Science, the Computer Science course concentrates on a specific language such as C++, C, JAVA, Python, and so on. Students are taught the language over two years, progressing from beginner to intermediate level. As a project, they are expected to produce a working code at the end of class 12th.

Additional Subjects

If a student does not perform well in either of the primary subjects, he or she can seek admission based on the marks earned in the supplementary subject. Many schools offer a mandatory additional/optional subject. After one more topic, the total number of scientific stream subjects in classes 11 and 12 is six. Physics, chemistry, mathematics, and biology are required courses in both the non-medical and medical streams. The following are the optional subjects available to students:

Physical Education (PE)

Physical education is a high-scoring optional topic. There is a practical subject worth 30 points and a theory subject worth 70 points. The topic was established to bring about changes and improvements in human bodies through regular exercise. Project work, a track race, a long jump, and other physical education activities were included in the practical.


Economics is a required course in the commerce stream, but it is also a popular optional subject in the scientific stream. Economics is a fascinating study that focuses on national GDP, national incomes, microeconomics and macroeconomics, demand and supply chain, and so on. Economics is an excellent option for a science stream course.
