Sure it is but it takes hard work! My son was the grade officer at his fraternity this year (it has some fancy name) but he had to study 3 hours a day most days with the pledges and make sure anyone with issues got the help they needed (tutors, office hours, extra sessions, etc.). Almost all that started their first semester low did better their second semester. Most had to re-learn how to study, what worked and what didn’t, how much time to spend (not over study and not under study). Bottom line is that you can’t slack off. You have to set hours to study and stick with them. You have to go to class. You need to go to office hours or tutoring sessions even when you don’t think you need to. Good luck!
