Dear Viraj, as a repeater, you have been there and done that. So you have an advantage over many other candidates in the terms of time management, exam pattern and the syllabus. So utilise this to your advantage. You must be aware that Biology alone has 90 questions and questions in Physics and Chemistry sum up to 90. Just make sure that you dont attempt a question whose answer you are not aware of. With negative marking in place, your wrong answer mighy take away 1 mark while leaving a question unanswered neither takes away or gives you a mark. The basic syllabus is from your 10+2 and all you need is to read your text books in and out. And make sure you go through the previous papers and check the pattern of questions being asked. Prepare well and let off the stress and relax at times when you need a break.
