Usually professors are jubilant to see you outside of class for an appointment and answer any emails because they understand your demanding schedule with athletics. This is a common problem amongst athletes. After a day of workouts in the gym and then training with the team, it is not going to get any easier when it comes to classes. So make sure you schedule time early with your professor if it’s to do with class work. If it’s to do with classes in general regarding not liking the class, wanting to switch classes then book a time to see your advisor. All teams have academic advisors so utilize them fully. They are there to help.
