Preparation Tips from ALLEN Overseas:

  1. Analyze: For each subject, look at the unit-wise weightage table. Identify the chapters that carry the highest marks.
  2. Prioritize: Schedule more study hours for high-weightage topics. For example, in Maths, give Calculus top priority.
  3. Understand the Pattern: Look at the typology of questions (Remembering, Applying, Analyzing). This tells you how you will be tested. Practice accordingly.
  4. Plan for Practicals: Don’t ignore the 30-mark practical exams. They can significantly boost your overall percentage. Start your project work early.
  5. Download Official Syllabus: Use the links provided to download the latest syllabus PDFs from the official CBSE website for the most accurate information.
