I scheduled my classes around the daily Mass schedule at my parish, and used my spare time to make holy hours. Also, being poor helped me grow in the virtue of detachment, as well as school work and studying helped with self discipline. And let’s not forget sleep deprivation from pulling all-nighters and then having to go to class in the morning.
If you have to do any psychology, sociology, women’s and gender studies, or English Literature classes you may run into the issue of content issues. I had to take a women’s study class that was an absolute load of garbage. I met with the department chair and program head and made a formal complaint about the content. They revamped the class and no longer make it mandatory. That being said, my women’s studies instructor was a catholic who absolutely hated St Thomas Aquinas, so I made it a point to read his writings while waiting for her to start class.
