Senior Secondary Class is essentially a career-making class, and Science is the most sought-after course at this level for pursuing the ambitious career of a doctor, an engineer, a scientist, a research scholar, etc. To realize this dream, a student must perform exceptionally well in this class. It is thus of utmost importance that all Science books — Physics, Chemistry, Biology and Mathematics for this class are designed to provide complete knowledge of these subjects in the most presentable manner. Pradeep’s books are the only books meeting this requirement in the most innovative way for more than 30 years.
