About 13 lakh candidates across the country take part in the SSC exams at the beginning of February every year. Usually students from three departments in SSC take part in the exams in humanities and business education.

There are three department-based subjects for humanities students, one of which is Biology. If you are a student of science then you must know how difficult biology is for them. Which is why we must have an idea about biology as exam preparation.
