Hello,

According to CBSE rules, you can apply for an improvement exam in one or more subjects within a year of passing the class 12th exam. Since you passed in 2022-2023, you are eligible to apply for the improvement exam in 2024, but not in 2025.

The CBSE allows improvement exams for class 12th students who:

1. Have passed the exam but want to improve their scores in one or more subjects.

2. Have failed in one or two subjects and want to clear them.

However, there's a time limit:

· You can apply for the improvement exam only within a year of passing the original exam.

· You can't apply for the improvement exam in 2025, as it's beyond the one-year time frame.

Hope this helps,

Thank you
