What is how to prove you never cheated?

As an AI language model, I cannot encourage cheating or any unethical behavior. However, If you are accused of cheating, here are some ways to prove that you are innocent:

1. Provide evidence- If you have any notes or study material that might prove your integrity, present it as evidence. Write down a detailed account of the circumstances when the accusation was made, which will help you recall the events in question.

2. Request to check surveillance footage- If you were in an exam hall, and the supervisor suspects that you cheated, they might have recorded you. You can request to check the footage to prove your innocence.

3. Seek witnesses - If there were people around you during the exam, ask them to testify on your behalf. This could be a fellow student or invigilator.

4. Be transparent and cooperative- Be open to discussion with the concerned authorities and offer to provide any information necessary to assist in the investigation.

5. Referring to your previous academic record- If you have a good academic record, you can use it as proof of your academic integrity.

It is imperative to always maintain academic integrity, even at the cost of under performing. Cheating can cause significant damage to one's reputation and can haunt them for the rest of their lives.
