In college, as long as you don't skip classes every day and don't read books at all, you won't fail so many subjects. In this case, you will be demoted if you regret it again. Admit your mistakes to your mother and ask for forgiveness, and then use your spare time and holidays to find a part-time job to reduce your mother's burden. At the same time, you should also use snacks in your study, at least don't let yourself fail again.
