Sure, as long as you have time to clean up, no problem! University is not a high school, after all, it is recognized by adults. As long as you don't do anything illegal, no one will care! When we were freshmen in military training, some people were willing to get up half an hour or an hour earlier than other students every morning to make up. Instructors and tour guides didn't care! It depends on your major. Like my roommate's major, I was completely immersed in my homework when I was a sophomore, and I didn't have time to make up ... but I suggest not spending too much, which will hurt my skin. I am still young. It's not too late to act when preparing for the third year of high school. Let's spend some time on other meaningful things I wish you a happy university.
