Hello,

If you take an improvement exam after passing your 12th standard exams conducted by the Punjab School Education Board (PSEB), the following generally applies:

1. Improvement Exam Results: The result of the improvement exam will replace your previous marks in the subjects you took for improvement. This means the new scores will be considered for academic and admission purposes.

2. Previous Results: Your previous marksheets will not change; however, the new marks will be reflected in a new marksheet or certificate issued after the improvement exam results are declared.

3. Official Records: Your academic record with the updated scores will be considered official for purposes like further education or job applications.

Always check with the PSEB or the institution where you are applying for the exact procedure and how they handle improvement exam results.

Hope it helps!
