Science and math require more study time than most students realize. Successful students study 25 to 35 hours each week (about two hours for each course credit). However, most high school students study less than three hours per week. This is not enough time in college, where students are expected to master lots of advanced material mostly by studying on their own outside of class. That is why we ask Sac State students to commit 25-35 hours per week to studying. Learn more about the college's Commit to Study program.
