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.

Hello

Yes, if you’re not satisfied with your marks even after the improvement exam, many education boards allow you to reappear as a private candidate next year to improve your scores. This means you can register independently, study at your own pace, and take the exams without attending regular classes. It’s a good option to improve your results and open up more opportunities for higher studies or careers. Just make sure to check the specific rules and deadlines of your education board so you don’t miss the registration window. Keep your focus, and you will do better next time.

Hello Aspirant,

Yes, in the case that you appeared for the 2025 improvement exam and your roll number is different from what was on the previous year’s marksheet, the board will usually release a new migration certificate. This is because the migration certificate will reflect the most recent exam details, roll number and passing year. You can apply to get it from your board using the process prescribed by them either online or through your school/college.

Yes, if you miss the 1st CBSE exam due to valid reasons, then you can appear for the 2nd CBSE compartment exam.

From the academic year 2026, the board will conduct the CBSE 10th exam twice a year, while the CBSE 12th exam will be held once, as per usual. For class 10th, the second phase exam will act as the supplementary exam. Check out information on w hen the CBSE first exam 2026 will be conducted and changes in 2026 CBSE Board exam by clicking on the link .

If you want to change your stream to humanities after getting a compartment in one subject in the CBSE 12th Board Exam , you actually have limited options to qualify for your board exams. You can prepare effectively and appear in the compartment examination for mathematics again. If you do not wish to continue with the current stream, you can take readmission in the Humanities stream and start from Class 11th again, and continue studying for two more years to qualify for the 12th examination.

The GUJCET Merit List is prepared based on the Class 12th marks and GUJCET marks received by the students. CBSE students who are not from the Gujarat board can definitely compete with GSEB students, as their eligibility is decided based on the combined marks scored by them in GUJCET and the 12th board. The weightage of the GUJCET score is 40% and the weightage of the class 12 scores is 60%.
