If you are not satisfied with your UP Board result, the scrutiny process lets you request a re-check of your answer sheet. Under scrutiny, the board re-verifies whether all answers were marked and the totals were added correctly.
This page explains who can apply, the application window, the fee per subject, and how revised marks are issued if a discrepancy is found.
What is checked during UP Board scrutiny?
Scrutiny re-checks unmarked answers and totalling errors. It is not a fresh re-evaluation of answers. How are revised marks issued after scrutiny? If a change is found, the board issues a corrected marksheet reflecting the updated marks.
