How to prepare for Class 12
Preparation Tips for Class 12
You need to know what to study, how to study, how to manage time,how to manage accuracy every question/exam and where to look for references for better exam result. Below is a list of subjectwise pointers for your preparation.
Mathematics
 The best way to learn it is by practicing the problems as much a possible. It is highly recommended that problems be practiced till good confidence is achieved.
 It is important that you spend more time on working out problems you’re weak at and practice it until you satisfied to achieve. Divide time for each unit at your comfort, depending on the total number of marks, and your level of proficiency in it.
 Focus on important topics, such as those given below, will definitely help:
 Elementary Transformation to Find the Inverse of a Square Matrix
 Properties of Determinants
 Matrix Method
 Limit of Sum
 Properties of Definite Integrals
 Application of Integrals
 Concept of Line and Plane in 3D
 Linear Programming
 Bayes’ Theorem
 Maxima and Minima Application Problems
 During the exam read the question paper carefully,analyse it well and select the best questions to solve first. Attempt the sections that carry more weightage/marks first.
Biology
 Remember biological terms, practice diagrams and be thorough with different processes.
 Biology course content can be serious and may need multiple readings due to its theoretical nature.
 Using flash cards can be a good memory retention technique.
Physics
 Practice derivations at least 8 times and sovle and practice questions on the basis of important derivations. Give special attention to Electrostatics, Magnetism and Optics as they might prove to be invaluable.
 Solve at least 8 sample question papers on the basis of the derivations you’ve learned. This will give you an idea about where you’re going wrong and how you could improve.
 Attempt as many conceptual questions on those derivations as you can. This will give you a better understanding of the subject.
 Look for new questions on similar context from previous year’s question papers, sample papers and other model test papers.
 Always time yourself while solving sample papers as it will help you better manage time during the exam.
Chemistry
 Revise the notes you’ve prepared throughout the year if not then refer to the best notes online and resort to videos for easy to understand concept. They will help you memorize the subject in a systematic way.
 Make a note of various formulae and stick them on a wall or your study table. Try to read and memorise them every time you pass them.
 Focus on the basics of important topics like p, d and fBlock Elements.
 Study and Practice Raoult’s Law, Adsorption Isotherm, Nernst Equation, Molar Mass Determination, Packing Fraction etc. as they contain important and frequently asked questions.
 Solve at least 8 sample question from the numerical topics you’ve learnt. This will give you an idea about where you’re going wrong and how you could improve.
 For Organics, revise few important and famous reactions like Cannizzaro, Aldol, Hoffmann, Friedel Crafts Reaction etc.
Previous Years’ Papers for Class 12 in School Connect Online
Practicing model papers is important like previous year papers,sample papers from various resources, as this helps you simulate the real exam for m. Make sure that you practice regularly so that you can learn all formulae by heart and solve problems easily on the day of the exam.
So practice is an essence for your success in exam,then practice as much as possible for your best performance
