High School Referral
Don't want to pay hundreds of dollars for online classes?
Need to improve a grade before applying to college?
Stressed about graduating on time?
Need more classes than fit in your high school schedule?
High School Referral is your free, online, self-paced, independent study solution! HSR allows high school students the opportunity to retake classes to earn a higher grade, make up credits, and/or get ahead in their studies.
Mt. SAC instructors supervise the classroom and provide individual instruction and support. Students must be currently enrolled in high school and have parent and counselor consent to participate.
