 The first and foremost of many major career-related decisions you will make is selecting a Sceince subject stream for Class 11th and 12th. After spending your prior years in a school studying a wide range of subjects, this is the moment when you have to choose a specialised stream that best meets your interests, abilities, and career aspirations. Don't worry if you haven't yet defined a specific career objective; there is still plenty of time to do so. 

While choosing a stream is easier than choosing a career, it is still important to make an informed decision because your stream might influence your entire career. After Class 10th, there are three main streams to choose from Science, Commerce, and Humanities/Arts, each with its concepts and theories, methodologies, subject possibilities, and career options. 

Science comprises scientific theories and applications, whereas Commerce comprises trade and business, and Humanities involve the liberal arts.  

In this blog, we will focus on the 11th science subject. Knowing what knowledge each subject offers will be of great assistance to you. So let's discuss the 11th science subject.

Subjects in the Science Stream after Completing 10th Grade

The Science stream is divided into medical (PCB) and Non-medical (PCM). The distinction between the two is in the third subject chosen. In other words, while medical and non-medical students must take Physics, Chemistry, and Mathematics, the medical stream requires Biology as a third subject instead of Mathematics. Lastly, students can choose any optional subject to complete five subjects alongside one language subject, English.

Detailed information about the 11th Science subject is given below:

1. Physics

Physics is the science that includes matter, motion, energy, and force, and it is one of the world's oldest-studied academic areas. It focuses on figuring out how things work and function and come in contact to generate more energy for further motions. Physics advancements, such as studying electromagnetic, thermodynamics, mechanics, nuclear physics, and solid-state physics, have enabled tremendous technological improvements. Physics in the 11th and 12th grades aids in developing observational, analytical, investigative, and decision-making skills, as well as conceptual comprehension, creative thinking, and problem-solving abilities.

What Will You Learn In Physics And What Opportunities Can It Bring To Your Career?

With physics, you'll learn to think in a whole new way. You'll understand how the laws of nature work and why the universe behaves the way it does. You'll also get to explore concepts such as gravity and electricity, gaining valuable insight into the physical world around us. And once you have a strong grasp of these principles, you could pursue various fascinating careers.

For instance, if you master physics, you could become an engineer and use your knowledge to develop new technologies that benefit society. Or you might go into research and become a scientist, investigating the mysteries of the universe. Alternatively, you could apply your skills in medicine and help make advances in healthcare. 

No matter what field you choose, understanding physics will open a world of possibilities for you. So if you want to take your career to the next level, don't miss out on this chance to enrich your mind and expand your professional prospects.
