I rewatched all the seasons. I liked Kirishima the first time but didn't think much of him, now I rewatched and I love him now.

Also, I feel dumb. I always wondered what's with Sero's helmet and only when I rewatched it did I realize that it resembles a tape dispenser...

Izuku Midoriya:

Only then will he remember he forgot to study, too busy with all his training and hero stuff so he will nervously chuckle and say he didn't do it so he can't help you before suggesting Momo to you, saying he heard from the others that she's an excellent teacher.

Katsuki Bakugo:

He will huff and say fine. When you don't pay attention or did something wrong, he would smack your head with his book, telling you to pay attention or to stop failing. He wouldn't smack you hard enough to hurt you, just softly to get your attention back to the book and in hopes to knock some sense into you.

Shoto Todoroki:

He will shrug and say you can come over to his place and study with him. He made sure his father wasn't home before he brought you though. He told you if you have a question or anything you don't understand to just tell him and he will help you. While both studied together, his big sister was very nice and brought you both some snacks and drinks to enjoy while studying.

Ochaco Uraraka:

She will get nervous, saying she's not sure she knows everything and be much help but she will help you as best as she can. She invited you over to her place since she lives alone. She wouldn't have done it if she lived with her parents, then she would be too embarrassed and nervous to bring you over. As you both studied, she was really hoping she was being any help to you while asking you a few times if you are doing okay or if you need any help with anything.

Tenya Iida:

He will be quick to ask what subject, which part you are failing at and how you can learn the best way. When you told him the best way you can learn something, he made sure to use that way as he explained to you what you didn't understand so you can understand him and hopefully get it.

Eijiro Kirishima:

He will excitedly tell you he can help you with it. When you left, he was quick to run to Bakugo, telling him to help him learn the subject you are learning so he can be sure he does not say anything incorrect and looks as if he's extremely smart. So after some harsh study sessions with Bakugo, he helped you. When you told him he's so smart, he rubbed his forehead, mumbling you have no idea.

Tsuyu Asui:

She usually helps her little siblings with studying so if you ask her to help you learn this subject you are having difficulties with, she will smile and say of course. She will let you come over to her house and she will help you study. Once it's done, she will ask you if you want to stay for dinner.

Momo Yaoyorozu:

She was very happy to help you study and explain anything you need explained. She will serve you whatever drink you want and some cookies. She was very patient with you, assuring you everyone can fail at a subject and there is no need to feel ashamed by it. Whenever you did great, she would be so happy and proud, praising you for how good you are doing.

Denki Kaminari:

When you asked him, he laughed before he stopped when you didn't look as if you were joking then asked if you are serious. When you nod, he panicked, saying even he needs help with his studies so he can't help you before he said wait and rushed away. When he returned, he excitedly said he asked Momo and she's willing to help you both out.

Kyoka Jiro:

She got nervous, awkwardly saying she can try. Whenever you asked a question, she let out a little "euhm", really hoping what she is about to say will make sense and that she isn't just gonna confuse you and that it is even the correct information. When it was over, she let out a sigh before saying she hopes she was any help.

Fumikage Tokoyami:

He will tell you he's not sure he can be much help but he will try to help you. So if you have a question, he will first check his book to make sure he's right before he begins answering it and explaining it, trying his best to not make it too confusing.

Mina Ashido:

She let out a chuckle and said she didn't even study herself. She told you about last time she studied with Momo and how she aced her test so you should go ask Momo. So both asked Momo, who was glad to help you two out.

Yuga Aoyama:

He will smirk and proudly say he will teach you. When you asked him if he didn't score low on the test though, he gave you unimpressed eyes before telling you you should believe in your boyfriend then dragged you away to go teach you this subject. He was more focused on looking good and posing though so if you asked something, he gave you a quick answer that even you knew was wrong.

Eri:

She won't be able to help since she never went to school so she doesn't know this stuff, but she will tell you that you can do it and she will root for you. While you are reading the book, she will be sure to be silent so she doesn't interrupt you.
