Right of someone unknown

I am a 17 year old currently studying intermediate. The intermediate education is provided by colleges in my country. In my secondary exams (on the basis of which students get admission in college for inter) I remember I asked a question of a friend during the exam to confirm a doubt. Now I realize that by doing that I may have disfavoured someone else who did not cheat. Now, I am in the final year of inter. Should I discontinue studies because studying in this college may have been someone else's right?
