Question: I cheated on a school test and I feel guilty. What do I do?
Answer: We all make mistakes in life. That is why Hashem created Teshuva, repentance, to correct our actions. In order to do a proper teshuva, one must regret their act, speak out what they did wrong and commit to not do that deed again.
What type of teacher/administrator runs your class/school? Would s/he be understanding if you came clean and admitted your mistake? If so, it may be worth it to tell them. You may feel better after doing so.
