During Campus Legend Mode, your scholastic achievement is important. So, for instance, if you need a boost to your player's GPA, choose to go study with a tutor. This will increase your test scores, and eventually, your GPA will increase. You could also choose to study on your own, which will give you possible questions and answers on your tests. Simply write down the answers or keep a laptop handy, where the answers can be quickly researched on the internet.
