All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
If you obtained the grades that qualify you to enter the university without cheating, then it is permissible for you to apply to enter the university.
The fact that you cheated in the test does not prevent you from applying to the university, but you have to repent of cheating.
For more benefit on the ruling on certificates and earnings if one cheated in exams, please refer to Fatawa 397198, 344719, 358828, 191489, 355567 and 362809.
Allah knows best.
