All of the chapters listed above are equally important and can be grasped with consistent practice and effort.

Benefits of Solving Previous Years’ Question Papers

Some advanced concept-oriented chapters in Class 12 require extensive practice. Solving previous year’s question papers is extremely beneficial when preparing for a board exam. Here are some of the benefits listed:

  • Students will be able to analyze the nature and types of questions asked in previous CBSE Boards. The marking scheme will also inform them about the content required for each answer and allow them to plan them in advance. 
  • Students get a feel of what their final examinations will be like. They can improve their concentration and stamina by solving CBSE Class 12 previous year’s papers. This will give you a significant advantage in the exam.
  • By practicing these question papers, students will gain knowledge about their strengths and weaknesses. This can help them strategize their answers and prepare accordingly. Also, students can boost their learning of specific topics if they feel unprepared for them.

Preparation Tips

Students should concentrate on finishing the syllabus and begin with their revisions. Additional books and test papers can be used to gauge their performance. It is important for students to not get overwhelmed and to keep their cool throughout their preparation. Here are some tips students can follow to make their preparation an effective and rewarding one to score maximum marks.

  • Choosing the best and essential materials will ensure better points. Students can use the solutions given to have an in-depth understanding of the concepts. This will help them create impressionable answers
  • Creating a timetable and set dates on which topics are to be completed helps students to stay on track. Subjects with more weightage and difficulty can have more time to study
  • Putting in consistent work is crucial for students to get their desired scores. Skimming through the chapters for the first time at the last minute will not only create stress and anxiety but also make your chances of securing good marks slim
  • While reading through the textbooks and solutions, students may make their own short notes. These should be pointers and not lengthy notes written in such a way that reading them only takes 2-5 minutes. For example, a long definition can be broken into pointers so that the student does not miss the main part of it
  • Set a time period and check the time you spend on completing the syllabus. Students are advised to not drag their preparation time, as they must also spend valuable time on revision as well
  • NCERT Solutions for Class 12 will build your knowledge not just for the CBSE syllabus, but for the subject matter. You can easily download the solutions from Extramarks subject-wise and chapter-wise. You can add in practice questions by referring to sample question papers and previous year’s question papers
  • After covering the syllabus, students must start revising the notes they made. This will help them understand the basic concepts and their pointers will connect them together
  • To complete the practice needed for CBSE examinations, students need to solve previous years and sample questions. Students prepare lengthy notes and are well-prepared for the questions. However, they don’t prepare for the time they should spend per question. Therefore, they end up spending most of the time writing or thinking about one answer while ignoring the rest. They can time themselves and evaluate their performance by solving these question papers.  By solving these question papers, students can also gauge their strong and weak subjects and work on them. This should be done at least 2-3 months prior to the examinations
  • It is important for students to work on feedback and be open to change. While solving the previous years and sample question papers, Regular self-assessment and self-reflection will guide students
  • With all this rush, it is absolutely necessary to keep one’s health in mind. Drink plenty of water, take regular walk breaks around your favorite neighborhoods, and talk to people who mean the most to you. It keeps your head in the game and gets you motivated
  • Make sure you reach the exam hall at least 15 minutes before the time mentioned. To perform your best, it is important that you keep calm and avoid undue stress
  •  When the examination starts, be sure to thoroughly read the paper and first answer the ones you’re most confident with
  • Leave the last 10-15 minutes to review the paper. Make sure that you have mentioned all the points needed for the question
  • Ensure that you write the correct question number against each answer in the sheet. You can allocate the last 2-3 minutes of the exam to do so

7. Do I answer extra questions in the CBSE Board exams?

If you have sufficient time, you can. Most students do go for answering extra questions because the type of questions asked makes it easier to write crisp answers than it is in the regular examinations of schools. Answers with the highest marks are usually considered for calculating the final score. Solving previous years question papers will help you hone your time management skills.

8. How do I calculate my CBSE Board exam percentage?

Firstly, students need to calculate their CGPA. The CGPA is calculated by obtaining the sum of grade points in five major subjects and dividing it by five. Then, students must multiply their CGPA by 9.5 to get their percentage. For example, if a student has a CGPA of 8.0, then the percentage would be 8X9.5, which is 76%.

9. Are the CBSE exam results given in grades or marks?

Though the internal and external assessments will be given scores, students’ final report cards will only include their grades. It is done on a 5-point scale from A to E. CBSE has taken this step to promote a healthy competitive environment among schools and students.

10. How will the first term's final grades be calculated?

The total of the marks obtained in the two FAs (Formative Assessment) and the SA I (Summative Assessment) in a particular subject is calculated. Following that, it is converted into a grade and a grade point for that specific subject.

Term- I FA1 (ten percent) + FA2 (ten percent) + SA1 (20 percent) = 40%
