Biochemistry is a pretty interesting subject, there may be several rumours that this subject is very hard, this is not a subject for average students but it is wrong. You will study about enzymes, carbohydrates, proteins, fats, amino acids in details and you will find all of them pretty interesting. So if you work hard and don't panick, then only you will succeed and make self notes from the books and practice the structures to score more.

Good luck!!
