What Should I take PCB (Physics, Chemistry, and Maths) or PCMB (Physics, Chemistry, Maths, and Biology)?
It totally 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 want to pursue engineering after 12. Take both (PCMB) if you are not sure what you want to study. If you like to do courses in basic sciences, then you can choose your preferred subjects accordingly.
Is math harder than biology?
It depends on your aptitude and what you like.
They are very different subjects as well, so it isn’t a good idea to compare the two. It’s 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.
