I think it's a matter of mentality. I am a graduate student, but I have been accompanying my boyfriend to take the postgraduate entrance examination. I can see some changes in my state or strength. Especially when the countdown is two weeks, the whole person will become anxious, and this kind of situation you mentioned will happen, which is normal. Personally, I don't have to worry too much, just have fun ~ we are all people who have experienced the college entrance examination ~
