Frequently Asked Questions (FAQ)

Which optional subject is best for the 11th class?

(i) Medical – Psychology, Biotechnology, Mathematics, Economics, Home Science, Fine Arts, Physical Education.
(ii) Non-Medical – Computer Science, Economics, Physical Education, Engineering Drawing, Fine Arts, Psychology.

Is Computer Science hard in class 11?

Absolutely not. Class 11 Computer Science is more effortless than Maths, Physics and Chemistry counterparts.

What Should I take PCB (Physics, Chemistry, and Maths) or PCMB (Physics, Chemistry, Maths, and Biology)?

It depends upon your interests and educational background. If you want a quick answer, take PCB i f you want to study medicine after 12. Take PCM if you wish to pursue engineering after 12. Take both (PCMB) if you are not sure what you want to study. If you like to do introductory science courses, you can choose your preferred subjects accordingly.

Is math harder than biology?

It depends on your aptitude and what you like.
They are also very different subjects, so it isn’t a good idea to compare the two. It’s actually better not to compare to subjects, as they are different (which is why they are differentiated as subjects in the first place). A better comparison would usually be topics within the subject itself. But if you were to compare subjects, a better comparison would be between subjects like Biology and Biotechnology, Zoology and Botany, or Math and Physics.

What is EP subject in class 11th?

EP stands for EP(Entrepreneurship).
