Is a student's total (score) considered permissible (halal), and is it valid for him to continue his studies and work, knowing that he cheated in only two subjects in high school due to limited time for revision, and he was excellent and studied diligently in all educational stages, and excelled in college without cheating?

Cheating is a forbidden act, and the Prophet, peace and blessings be upon him, said: "Whoever cheats us is not of us." However, if the person mentioned is proficient in their work, qualified, performs it with sincerity and dedication, and has repented from cheating, then there is no harm in them taking on the job that their specialization allows.
