I could tell you guys a bit nervous (as Risa and Kozuki had nice big smiles when the recording finished!) during the dialogue. I liked the fact you extended the conversation by Kozuki's asking Risa to help him with the test prep. 'Teach' is OK but 'help' could also be good when you ask for help to study. You can say something like, 'I am not 100% sure about the contents, so do you mind helping me prepare for the test?' ぐらいがいいかもしれませんね。Very very nice job though! I liked.
