How much time is too much time? When you were in high school you went to classes between 30 and 40 hours per week.
A full load in college is 15 hours of class time. For every hour of class time you need 3 hours study/prep/homework for a total of 60 hours per week.
I assume you had at least 10-15 hours per week of homework/study/prep in High School….so they are similar in time requirements.
As for travel time, that is a personal choice you have made, not the fault of the college. My youngest lives in a college dorm on campus. She can reach classes in 5 minutes.
I did a graduate degree about 10 years ago that required a 6 hour roundtrip drive twice a week for 18 months, but I wasn’t going to leave my family to live near the school.
