It is necessary to maintain an incredibly strong grip on your subject. It is recommended that you revise with the previous year's question papers rather than simply memorizing answers from question banks. It will be best if you only get questions from them and try to find answers in books or make your own, based on your knowledge.

Simply being honest with yourself and working sincerely hard will help you get good grades not only in theory but also in practical and viva. Determination and dedication to your work are always rewarded.
