Если не трудно, можно мой ответ поставить, как "лучший" , я старалась))

Ответ:

I wish I won that race. I wish I got an excellent mark at school. I wish I was at home during the storm. If only I had more time to think, I would have written the last exercise in the test. If only I had been at school again, I would have studied better. If only I had done all my homework, I wouldn't had a bad mark at school.
