It's easy to ask "what should I do". Because you have taken a solid step in the right direction! The question now is, can you face up to your own problems? For example, if you say, "To tell the truth, I didn't cheat this time. I copied the answer before the exam and typed CF", you will be ready. Is it the same whether you cheat or not? Then from more than 20 students to more than 100 students, or the whole class counts down, then there is nothing to worry about.

The best way is to study hard, and don't have ideas such as copying answers, CF, QQ, who you like, and girls. If you really want to do well in your grades, you are ready to resist all temptations! Do not believe, you try!
