How to fill in the resume of teacher qualification certificate and repeat it in middle school?

If you fill in the wrong form, you will not pass the rigorous exam. But it may not be so strict, no one will check your background so carefully, so it doesn't matter much. Generally speaking, it has a certain impact. Repetition means that you have studied longer than others. Others have studied for three years, and you may have studied for four years. So the time difference you fill in will be bigger than others'. I hope my answer can help you. Good luck!
