Currently, as the Central Board of Secondary Education (CBSE) exams are underway, students enrolled in the Science stream for grade 12th are in the process of preparation for their upcoming Chemistry exam scheduled for February 27. The results of CBSE exams hold significant importance in students’ lives as they pave the way for admissions into esteemed institutions. Meanwhile, preparing for a grade 12th Chemistry exam requires a systematic approach, to assist students in their exam preparations, here are some valuable tips and strategies that could enhance students’ performance:
Understanding the syllabus:
In preparation for CBSE 12th Chemistry board examinations, students are advised to thoroughly review the syllabus set by the board. This ensures they are familiar with the topics they need to cover. Additionally, students should pay close attention to the practical experiments outlined in the syllabus, as their performance in laboratory assessments will also be taken into account during the examinations. Therefore, before commencing preparation, students should carefully examine both the theoretical and practical aspects of the syllabus. The allocation of marks for each unit in both theory and practical components will help students identify the topics with the highest weightage in the exam, allowing them to prepare accordingly.
Question paper pattern:
The exam is out of 100 marks, split into a 70-mark theory section and a 30-mark practical paper. The theory paper is structured into three parts – namely long answer questions, short answer questions and very short answer questions. The long answer section comprises three questions, each worth five marks. Additionally, there are nine short answer questions, each valued at three marks and ten short answer questions, each worth two marks. Furthermore, the paper includes eight very short answer questions, each carrying one mark. Moreover, there will be internal choices available for five questions from each section throughout the entire question paper.
Approach for conceptual understanding:
Physical Chemistry is highly conceptual, necessitating a thorough grasp of each concept before tackling problems. Students are advised to compile a list of all formulas and engage in practising numerical questions from NCERT textbooks. The question papers for both 12th and 10th-grade board exams are designed around the content of NCERT textbooks, closely reflecting the current CBSE curriculum. NCERT books serve as resources, providing valuable insights into key topics, exam formats and question types. It is advisable to regularly undertake mock tests concentrating on subjects such as Thermodynamics and Chemical Kinetics.
Use reference books:
There are numerous grade 12th chemistry reference books available in both physical stores and online platforms. It is believed that these resources enable students to develop a comprehensive understanding of the subject matter. Presented below are a few examples (Please note that these books have been selected under editorial guidance).

What do experts suggest?
Split chemistry into three main branches: Physical, Organic and Inorganic. Dedicate ample time to each, prioritising weaker aspects while upholding a solid grasp of all. Given the memorisation demands, utilise mnemonic tools, flashcards and visual aids to retain intricate chemical reactions and equations effectively.
