JAC 12th Result 2025: How to Calculate Your Percentage and CGPA

The Jharkhand Academic Council (JAC) has implemented a comprehensive grading system for the Class 12 examinations in 2025. Understanding this system is crucial for students to accurately calculate their percentage and CGPA. This article provides a detailed overview of the JAC 12th grading system, passing criteria, and the method to calculate your percentage and CGPA.

JAC 12th Grading System 2025 Highlights

JAC 12th Grading System 2025

The JAC Class 12 grading system is based on a five-scale mechanism, assigning grades from A+ to D based on the aggregate marks obtained out of 500.

JAC 12th Passing Marks 2025

To pass the JAC Class 12 examinations, students must secure a minimum of 33% marks in each subject, both in theory and practical components. This means:

Theory Subjects:

• For subjects with 80 marks in theory, students need at least 26 marks to pass.
• For subjects with 70 marks in theory, the passing mark is 23.

Practical Subjects:

• In subjects with 30 marks allocated for practicals, a minimum of 10 marks is required to pass.
• For subjects with 20 marks in practicals, students must score at least 7 marks.
• It's essential to pass both the theory and practical components separately to be considered successful in a subject.

How to Calculate Percentage Using JAC 12th Grading System 2025

To calculate your percentage:

Add up your total marks from all subjects (out of 500).

Use this formula:
Percentage = (Total Marks ÷ 500) × 100

Example:
If you scored 400 out of 500:
(400 ÷ 500) × 100 = 80%

This percentage can then be used to determine the corresponding grade and division as per the grading system.

JAC 12th Provision for Grace Marks 2025

To support students who narrowly miss the passing criteria, the Jharkhand Academic Council (JAC) offers a grace marks provision under specific conditions. The details of this policy are as follows:

• If a student falls short of the passing mark in a subject by less than 5%, grace marks will be awarded to help them clear that subject.
• If a student is failing in two subjects but the shortfall in each is less than 3%, they will receive grace marks in both subjects to pass.
• Students who haven’t received grace marks under the above two criteria but fall short of a higher division by up to five marks can be granted the minimum required marks to qualify for that division. However, their ranking or position in that division will be based on their actual marks.

JAC 12th Marking Scheme 2025

The marking scheme for JAC Class 12 varies across subjects:

Theory and Practical Distribution:

• Subjects may have different distributions between theory and practical components.
• For instance, some subjects may have 70 marks for theory and 30 marks for practicals, while others may have 80 marks for theory and 20 marks for practicals.

Assessment:

• Students are assessed separately in theory and practical exams.
• Both components must be passed individually to clear the subject.
• Understanding the specific marking scheme for each subject is crucial for effective preparation.

JAC 12th Compartment Exams 2025

Students who fail to secure the minimum passing marks in one or more subjects have the opportunity to appear for compartment exams:

• Eligibility: Students failing in up to two subjects are eligible for compartment exams.
• Application: Students must apply for the compartment exams through their respective schools or the official JAC website.
• Preparation: It's advisable to utilize this opportunity to thoroughly prepare and improve performance in the failed subjects.

Understanding the JAC 12th grading system is essential for students to assess their performance accurately. By calculating your percentage and CGPA correctly, you can set realistic goals and plan your future academic endeavors effectively.
