2. I've already said it's probation, so it doesn't matter how you defend it. No matter how you plead, you can't be acquitted.

3. yes.

My suggestion, since probation is already the minimum sentence, it basically does not affect normal life. You don't need to waste time on defense. Just say a few words. I have realized my previous mistakes, and I will be a good person and start over. Just be sincere. Others, it is useless to say more.
