Preparation Plan

How to Utilize Preparation Gap Between Two Exams?

CBSE provides enough gap between any two exams. If you have already covered your syllabus, you can utilize this time for revision and practice. Here we have provided a rough plan you can use during the preparatory gap between your exams:

Subject Exam Date Preparatory Days Provided as per CBSE Date Sheet Preparation Plan
Chemistry February 27, 2024 4 Days Day 1 – Pick the major chapters and revise all the concepts, formulas, etc. Practice questions from Physical Chemistry part
Day 2 – Learn and practice reactions from Organic Chemistry. Along side, pick smaller chapters with less weightage for quick revision
Day 3 – Solve 3-4 sample papers and previous years’ question papers
Day 4 – Revise the major topics again, keep practicing the question papers
Physics March 4, 2024 5 Days Day 1 – Go through your notes, note down all the major formulas, and derivations for all the chapters (specifically major ones)
Day 2 – Pick chapters of high marks weightage like Optics, Current Electricity, Magnetic Effects of Current and Magnetism and practice from your reference books
Day 3 – Start solving sample papers and previous years’ question papers and also revise other chapters
Day 4 – Keep solving as many questions as you can from different resources as Physics paper includes good number of numericals
Day 5 – You might want to go through your notes once again apart from practicing previous years’ papers
Mathematics March 9, 2024 4 Days (for Science Stream)
15 Days (for Commerce Stream)
8 Days (for Arts Stream)
For Maths, the only preparation plan that works is practicing important questions. Since each stream has enough number of preparatory days for Maths, students can solve a good number of question papers or sample papers apart from solving their regular textbooks or reference books. Commerce stream have more than enough days for this paper, if they wish they can divide the preparation with another major subject like Accountancy. 
Biology March 19, 2024 15 Days (if you have not opted Maths)
10 Days (if you have opted Maths also)
Whether or not you have opted Maths, you have sufficient days for Biology preparation. The preparation strategy should involve reading all the major chapters line to line as the competency-based questions in Biology are directly taken from the textbook. Learn your notes and practice diagrams along with labelling. Make separate notes for important direct questions that have high chances in board exams. Prepare notes for these questions in answer format that you can memorize and write in the final paper. 
Economics March 18, 2024 8 Days You can divide your days equally between Macroeconomics and Microeconomics revision for first 5 days. Last 3 days, focus on solving sample papers and previous years’ question papers. 
Accountancy March 23, 2024 4 Days Day 1 – Focus on preparation of Part A (Accounting for Partnership Firms and Companies), revise all the formulas and practice questions
Day 2 – Pick chapters from Part B (Financial Statement Analysis) along with continuing Part A
Day 3 – Solve the sample papers and previous years’ question papers
Day 4 – Keep practicing questions from different sources including your textbook, reference book, and question papers

Frequently Asked Questions

Frequently Asked Questions

Ques. How should I prioritize chapters based on their weightage in CBSE Class 12 exams?

Ans. Prioritizing chapters based on their weightage in CBSE Class 12 exams is a strategic approach that can help you allocate your study time effectively and focus on topics that are more likely to appear in the question paper. Here's a step-by-step guide on how to prioritize chapters:

  • Understand the Chapter-Wise Weightage:
    • Familiarize yourself with the official chapter-wise weightage provided by CBSE for your specific subjects.
    • Obtain the latest information from official CBSE documents or announcements.
  • Identify High-Weightage Chapters:
    • Identify chapters that carry a higher weightage in terms of marks. These chapters are likely to have a more significant impact on your overall score.
  • Categorize Chapters by Weightage:
    • Group chapters into categories based on their weightage, such as high, medium, and low.
    • Prioritize studying high-weightage chapters first.
  • Focus on Core Topics:
    • Within each chapter, identify core topics or concepts that are crucial for understanding and solving problems.
    • Allocate more time to mastering these core topics.
  • Analyze Previous Year Question Papers:
  • Balance Between Theory and Application:
    • Ensure a balance between theoretical concepts and their practical applications within each chapter.
    • Some chapters may have more weightage for theoretical questions, while others may emphasize problem-solving skills.
  • Consider Your Strengths and Weaknesses:
    • Assess your own strengths and weaknesses in different chapters.
    • Prioritize spending more time on chapters where you feel less confident.
  • Create a Study Schedule:
    • Develop a realistic study schedule that allocates more time to high-weightage chapters.
    • Break down your study sessions into manageable chunks, covering different chapters each day.
  • Regular Revision:
    • Plan for regular revision sessions to reinforce your understanding of key concepts.
    • Focus on revising high-weightage chapters more frequently.
  • Seek Guidance from Teachers:
    • If you have doubts or need clarification on specific topics, don't hesitate to seek guidance from your teachers.
    • Teachers can provide insights into the importance of certain chapters and offer additional resources for study.
  • Stay Updated with Changes:
    • Keep yourself updated with any changes or updates in the syllabus or exam pattern.
    • Adapt your study plan if there are revisions to chapter-wise weightage.

Remember that while chapter-wise weightage is a useful guide, it's also essential to have a comprehensive understanding of all the chapters. Striking a balance between high-weightage and lower-weightage topics ensures a well-rounded preparation for your CBSE Class 12 exams.

Ques. Does CBSE follow the chapter-wise weightage strictly in question paper setting?

Ans. While CBSE provides chapter-wise weightage as a guideline for students, it's important to note that the board may not strictly adhere to these weightages in question paper setting. The chapter-wise weightage is intended to offer students insights into the relative importance of different chapters and topics within a subject, helping them prioritize their study efforts.

However, the actual distribution of questions in the exam paper can vary, and CBSE may introduce some flexibility in question paper setting. Here are a few points to consider:

CBSE may have a broad idea of the weightage, but it doesn't necessarily mean that the exact number of questions or marks will be allocated according to the provided weightage.

  • Varied Question Types:
    • Question papers are designed to assess a range of skills, including understanding, application, analysis, and critical thinking.
    • CBSE may include questions from various chapters to ensure a comprehensive evaluation of students' knowledge.
  • Inclusion of Conceptual Questions:
    • CBSE may include questions that test fundamental concepts, irrespective of the specific weightage of a chapter.
    • This is done to evaluate students' depth of understanding and application skills.
  • Adaptation to Changes:
    • The board may adapt question paper patterns to changes in the syllabus, educational requirements, or to introduce innovative assessment methods.
    • Students should be prepared for unexpected variations in question paper structure.
  • Emphasis on Learning Objectives:
    • CBSE aims to assess whether students have achieved the learning objectives outlined in the syllabus.
    • Question papers are designed to reflect these objectives rather than strictly adhering to predetermined weightages.

In conclusion, while the chapter-wise weightage is a valuable tool for students to organize their study plans, it's equally important not to solely rely on it. Students should aim for a comprehensive understanding of all chapters and topics within the prescribed syllabus. Regular practice with solving sample papers and previous year question papers is also recommended to familiarize themselves with the varied question types that may appear in the actual exams.

Ques. Is the chapter-wise weightage the same every year, or does it change for CBSE Class 12 exams?

Ans. The chapter-wise weightage for CBSE Class 12 exams is not necessarily the same every year. While the Central Board of Secondary Education (CBSE) provides a broad outline of the chapter-wise weightage in the official syllabus, there can be variations from year to year. Several factors contribute to changes in the chapter-wise weightage:

  • Curriculum Revisions: If there are updates or revisions to the curriculum, CBSE may adjust the weightage to reflect changes in the importance of specific topics or chapters.
  • Educational Objectives: CBSE may modify the weightage to align with the educational objectives and learning outcomes outlined in the curriculum.
  • Changes in the overall exam pattern or format may lead to adjustments in the distribution of marks across chapters. Check latest Subject-wise CBSE Class 12 Exam Pattern
  • Feedback and Analysis: CBSE considers feedback from teachers, subject experts, and educational stakeholders when determining the weightage. If certain topics need more emphasis based on performance trends, adjustments may be made.
  • The introduction of new topics or units in the syllabus may result in changes to the chapter-wise weightage.
  • Technological Advancements: The inclusion of modern and relevant content, especially in subjects like science and technology, may influence the weightage assigned to specific chapters.
  • Examination Reforms: Ongoing efforts to introduce examination reforms may lead to adjustments in the distribution of marks to align with the broader goals of assessment.
  • Subject-Specific Considerations: Different subjects may undergo changes based on subject-specific considerations and emerging trends in academia.

Given these factors, it's crucial for students to refer to the latest official CBSE documents, including the most recent syllabus and notifications, to obtain the accurate chapter-wise weightage for their Class 12 exams. Additionally, schools often receive official communications from CBSE and can provide the latest information to students.
