Must a female student correct her total grades if they are erroneously higher than they should be, or is it not considered forbidden if she does not correct them?

If you did not deserve the grade you received and there was an error in your total score, then it is a matter of trustworthiness and justice that you strive to reveal the truth and restore matters to their proper state. This is because students' grades are relied upon in assessing their levels and future careers. Cheating in this regard is harmful and leads to matters being entrusted to those who are undeserving, which is a betrayal of trust. Concealing the truth is an injustice and a diminishing of the rights of those who are more deserving. The Prophet, peace and blessings be upon him, said: "Injustice will be darknesses on the Day of Resurrection," and "Whoever cheats us is not of us." The Prophet, peace and blessings be upon him, commanded the fulfillment of trusts, and considered the betrayal of trusts to be one of the characteristics of hypocrites. He also made the loss of trusts a sign of the approaching ruin of the world.
