CBSE Class 12 Preparation Tips for Chemistry
We have accumulated some good CBSE class 12th Chemistry board exam tips and chemistry tricks for class 12 that will help candidates looking for exam preparation.
Syllabus & Marking Scheme
The Preparation tips for the CBSE Class 12 Chemistry exam are important among all others. Candidates need to thoroughly read and analyze the syllabus once. CBSE class 12 syllabus for Chemistry covers the fundamental concepts of Chemistry. The syllabus helps in knowing the minor and major details of the syllabus, which eventually helps in making a proper study timetable. They should also keep track of the CBSE Class 12 Date Sheet. Candidates need to be clear about the topics included from their basic level to advanced.
Make an Effective Study Plan
Managing time is one of the most important parts, it needs to be done wisely. While preparing for class 12 exams, students need to give time to other competitive exams as well. Students should set a day, week, and monthly based target timetable. Remember to include all the topics and devote time to every subject equally.
Strengthen Concepts
We know that if the concepts are strong, then it is easy to deal with a variety of questions. Students need to work on their understanding skills. Do not neglect the areas in which a candidate is weak. One is advised to keep a separate time slot for concepts in which they are weak. Another one of the big Preparation tips for CBSE Class 12 Chemistry is group study.
Evaluating Yourself
Self-evaluation always helps in finding the weaker points, it would be better to keep an extra time for that. Practice CBSE Class 12 sample papers can help in evaluating your preparation for the exam. Students can also go for previous year papers, this should be done after all concepts and topics are covered. Try to solve the questions within the time limit to save time so that proofreading can be done. All this will help in self-analysis that will improve your preparation.
Practice Numerical Problems
Numericals can be tough, but doing daily practice can help you master them. It would be helpful if students try to solve at least five to seven questions a day. This will also help in clearing concepts and understanding things in a better way. Daily practice will build on speed and accuracy with confidence during the actual test.
Make Short Notes
Short notes always help in revising concepts quickly. Students can look at these notes every now and then. This will help to remember things for a long time. It becomes quite simple to revise from short notes instead of going through the bulky textbooks once again.
