Study 25-35 Hours/Week
College will be more challenging than high school and require a greater personal commitment. In high school you were in school five days a week, six hours a day for a total of 30 hours per week. National studies show that, on average, high school students spend less than five hours a week on homework making the total commitment about 35 hours per week. In college you will be in class 15 or so hours a week. Across the nation, universities recommend that students study two hours per unit per week, or 25-35 hours per week. The total time commitment of 40-50 hours a week is quite reasonable, similar to a full-time job, and if you manage your time well, there is ample opportunity for other interests and activities.
You should study at least two hours per week for every unit of coursework!
