The student is advised to solve the problems without referring to the solutions. The student
has to analyze the given question carefully, identify the concept on which the question is framed, recall the relevant equations, find out the desired answer, verify the answer with the final key such as (a),(b),(c), (d), then go through the hints to clarify his answer. This will help to face numerical answer questions, better. The student is advised to have some standard reference book ready to strengthen the related concepts, if necessary. The student is advised not to write the solution steps in the space around the question. By doing so, he loses an opportunity of effective revision.
