Science is a vast subject stream that covers almost everything that we can see, touch, hear, feel and even beyond that. Everything in the world, no not only the world but the universe that we live in, falls under the ambit of science. However, during your 11th and 12th Class studies, you will be dealing with three main sub-streams of the subject, i.e., Physics, Chemistry, and Biology. In addition to this, you will also have Mathematics as one of the core subjects along with a compulsory language subject. With computer technology taking the center stage in the scientific study domains, you will also have computer science as a foundational subject. 

Present-day science is commonly isolated into three significant branches that comprise of the normal sciences (e.g., science, science, and material science), which study nature in the broadest sense; the sociologies (e.g., financial matters, brain science, and humanism), which study people and social orders; and the conventional sciences (e.g., rationale, arithmetic, and hypothetical software engineering), which concentrate conceptual ideas. There is disagreement, in any case, on whether the proper sciences really establish science as they don't depend on experimental evidence. Disciplines that utilization existing logical information for pragmatic purposes, for example, designing and medication, are depicted as applied sciences.

Science depends on look into, which is usually led in scholastic and research foundations just as in government organizations and organizations. The functional effect of logical research has prompted the rise of science strategies that look to impact the logical venture by organizing the improvement of business items, weapons, human services, and natural assurance.
