The CBSE Class 12 board exams are a crucial milestone for students, shaping their academic and career paths. With the 2025 syllabus introducing key changes in grading, exam patterns, and skill-based subjects, staying updated is essential. Whether you’re a student, parent, or educator, understanding how marks are calculated, grades are assigned, and the new 9-point grading system works can make a huge difference. This guide breaks down everything—from passing criteria to CGPA conversion—using real-life examples, expert insights, and official CBSE updates. Let’s dive in!
The CBSE grading system has shifted from marks-based to a relative ranking method, reducing exam stress while maintaining fairness. Here’s how it breaks down:
🔹 Real-Life Example: Riya scored 87% in Physics (A2), 92% in Chemistry (A1), and 78% in Maths (B1). Her CGPA would be: (9 + 10 + 8) ÷ 3 = 9.0 → 9.0 × 9.5 = 85.5%
How CBSE Calculates Your Final Score 🧮
CBSE uses a two-step process:
Relative Grading → Students are ranked, and grades are assigned based on percentile.
CGPA Conversion → The average of top 5 subjects is taken and multiplied by 9.5 to get the percentage.
