Class 12th Mathematics: The CBSE class 12 Maths exam is generally conducted in March annually. As the exam approaches, it's important for students to focus on smart revision strategies and improve problem-solving skills. In the final class phase of 12th Mathematics preparation, students should reinforce essential formulas, practice previous years’ question papers, and follow a strategic time-management routine to significantly enhance their chances of scoring well.

Mathematics is a subject where formula comprehension and practice are essential to perform well. For some, it provides a chance to improve overall exam performance, while others may find it challenging. Irrespective of a student’s current standing, the last preparation tips are crucial to strengthen their grasp of key concepts and take the exam with a planned strategy.

Class 12th Mathematics Revision Tips and Exam Day Strategy

As students prepare for class 12th Mathematics exam, it’s essential to spend the final hours wisely. Rather than rushing through new chapters or resources, they must focus on following a smart revision plan to memorise formulas and get exam-ready. Here are practical tips to help students make the most of their exam-day preparations:

Keep a Handy Formula Sheet

Write all the important formulas in a sheet and keep them handy for last minute revisions. Candidates must ensure the sheet includes key formulas from Calculus, Algebra, Trigonometry, Probability, and Coordinate Geometry. In the final days of class 12th Maths preparation, candidates should regularly go through the formula sheet for knowledge reinforcement.

Prepare With NCERT 

The CBSE board exam largely includes questions based on the topics of the NCERT textbook. As the exam approaches, one must revisit solved examples, practice questions, and mixed problem sets from each chapter. Additionally, students should look for patterns in questions asked in previous board exams, as some of them are expected to repeat with slight variations.

Practice Under Timed Conditions

In the class 12th Mathematics final preparation phase, it becomes crucial to improve time management skills along with problem-solving techniques. To enhance speed and accuracy, students must solve PYPs or take full-length mock tests in an exam-like setting. By simulating real exam conditions, candidates can effectively improve their speed and accuracy.

Create Exam Taking Strategy

Candidates should create a structured approach with a clear time allocation strategy for taking the actual class 12 exam. As the class 12 exam spans 3 hours, candidates should consider breaking down the exam into the following segments:

  • First 15 Minutes: Read the paper thoroughly, mark the easier questions, and decide the order of attempting the exam.

  • 40 Minutes: Solve the short-answer sections (A & B) quickly and accurately.

  • 60 minutes: Focus on the long-answer section C with clear steps and neatly written solutions.

  • 50-60 Minutes: Aim to solve all 6-marks questions with accurate calculations.

  • Last 10 Minutes: Revise the answers, check for mistakes, and ensure all calculations and units are accurately written.

Don’t Start New Topics

During the last days of class 12 Maths preparation, students must avoid starting a new chapter as it may increase confusion and stress. Instead, students should aim to cover the topics they have already studied. Additionally, they should prioritise practising various types of questions from the already covered topics.

Class 12th Mathematics High Weightage Topics

Candidates preparing for the class 12 CBSE Mathematics exam must have a clear understanding of chapter-wise mark distribution. Knowing the high-weightage chapters allows candidates to plan their revisions better and pass the exam with a good score.
