Physics can be another mind numbing subject which is why, it must be dealt with attention. Follow these simple tips to :
(i) Understand the break up: Study the previous year break up of questions to get a fair idea what sections to focus on. Usually, 55% of the paper (100 marks) is set from the XIIth syllabus and 45% (80 marks)from the XIth syllabus. As most students are already preparing for the board exam, they just need to accordingly set aside time to brush up the XIth syllabus as well.
(ii) Basics Matter: It is important to pay emphasis on basics and understand numericals and the reasoning that goes behind it. Most students try focus on short cuts, but it'll be more handy if you focus on understanding the logic behind a numerical.
(iii) Tabular Preparation: Before diving into solving numericals, students should keep a table of physical quantities and formulae handy and pay attention to units and conversions. It is important to keep in mind the units, as the question might ask a question in a particular unit and the answer choices might be in another unit. Be careful to not fall in this trap.
(iv) Travel in time: It'll be handy to solve at least the previous five year papers to get a clear understanding of what the focus points are. Try circle in the topics where you are sure you can score and look out for those questions on the day of the exam.
(v) Spread out your focus: Make a table for yourself and chalk down what topics are tough. Certain topics such as electromagnetism and mechanics might need more time than other topics. Also, around 40% of the paper is difficult, 40% of medium level difficulty and 20% of the paper is easy. Focus on tring to score full marks in the easy section and try mastering a few topics which are covered in the tougher segments to get an edge.
