Tips To Crack Class XII PCM
For those appearing for Class 12th exams with PCM subjects it may sound a diabolic experience. Here are a few useful tips for the last minute preparation:
The subject is divided into three chapters, Physical, Inorganic and Organic Chemistry.
In chemistry paper, p-block elements carry maximum marks. Hence, students need to give first priority to p-block elements to ensure good score, while keeping numerical of physical chemistry for the last. It will fetch a maximum of only 12 marks.
Besides, reasoning questions should not be missed. They add up to your score.
Examinee can score up to 28 marks from the second book of organics. The order of priority should be Nomenclature, Conceptual reasoning like radius, strength, polar solvents et al, reactions like the Friedel crafts reaction, Hoffmann reaction etc.
Around 30 marks are dedicated to the theory part of the examination. The questions under this segment need to be attempted with ease by judiciously utilising the time at hand and understanding the basics.
Like Chemistry, Physics is divided into three major parts – Classical Physics, Optics & Waves and Modern Physics.
The chapter on Optics carries 14 marks while the numerical part 20 marks.
The first book in this segment is based on theory. It encompasses classical physics with major chapters dedicated to magnetism. It consumes lot of time for which the examinee has to be prepared in advance.
Any question in physics can be posed in three different ways – Theory, Concept and Numerical. Derivations, reasoning etc. can arise as theory. Conceptual based questions can be asked from electrostatics & magnetism etc., and last but not the least Numerical.
First list all the important derivations before you contemplate on the concept behind them. This way you will be able solve the theory as well as the conceptual part of the question and there by dwell on the numerical part.
Similarly, you can make a list of formulae covered in the subject to solve the numerical part before preparing a list of sample questions based on those formulae. This way you can attempt all the three parts of the problem.
Be at ease while attempting to solve questions under the Modern Physics part. This segment covers Atoms, Nuclei, Communication Systems and Semiconductors. Since it requires much less time, you will have ample time to solve each question.
Like Chemistry and Physics, Mathematics too is divided into three major parts – Numbers,
Under this segment, a major portion is that of Calculus. Calculus carries 44 marks to add up to your total scores.
Vectors is the most important chapter in this segment that carries 17 marks while Matrices and Determinants 13 marks.
For Calculus, you need to contemplate on the basics with formulae. While attempting questions in this segment bear in mind that you have to list all the formulae with an example for each.
You are given 15 minutes additional time to evolve a strategy before attempting to solve the papers. Utilise these 15 minutes judiciously to score maximum possible marks.
