MBX FLEX is “flexible schedule” courses allowing students to create a summer school plan that works for them and their own unique learning style. Students will meet with credentialed teachers in a personalized learning environment with a blend of face-to-face (IN PERSON) and online coursework. Students will meet with teachers for 20, 2-hour or 24, 3-hour sessions for 2 semester courses (science classes meet for 24, 3-hour sessions) and 10, 2-hour block sessions for 1 semester classes, plus proctored tests, with the option of 1:1, 1:2, 1:3, and 1:4 teacher/student ratios.
While schedules are flexible and intended to meet your needs, MBX FLEX is a condensed and rigorous academic curriculum. Students are expected to complete work outside of the scheduled sessions and come prepared for each session. Students electing 1:2 or more ratios must follow identical schedules and be academically compatible. It is the responsibility of the student to find partners for 1:2 and higher ratios. MBX will keep a list of students requesting partners, however, will not take responsibility for confirming or matching compatible partners. Students who do not have partners may register in anticipation of finding a partner. However, if no partner is found, they will be withdrawn from the class, refunded the tuition less 10% administration fee. Alternatively, you may request to be put on a list for a partner by emailing Jennifer Williams (). MBX will not guarantee a compatible partner will be found.
UC/CSU A-G Subject Requirements
All MBX academic courses are accepted for credit on Mira Costa High School transcripts, with 5 credits awarded per semester class. A 2 semester class will receive 10 credits.
All MBX courses are eligible for UC/CSU approval and meet A-G subject requirements once placed on the Mira Costa transcript through Principal Certification (as described by UC Admissions)
If you attend a high school other than Mira Costa, you are responsible for ensuring that your grade will be accepted on your home school transcript and will subsequently meet the A-G subject requirement.

While vacations can be accommodated, sessions will be pre-scheduled. Students may schedule up to 5 sessions per week (Monday – Friday). Students enrolled in Science classes may schedule no more than 4 sessions per week. In addition to scheduled sessions, students have proctored tests and outside course projects and homework. All homework must be completed prior to the next scheduled session in order to advance to the next lesson. Students in 1:2 and higher ratios must advance at the same pace. Failure to maintain the same schedule and advancement may require additional session costs to ensure completion of course. Students should be aware that Flex delivers a very rigorous, condensed curriculum. Students will be expected to complete at least 2 or more hours of additional work outside of class between sessions. Students are advised against enrolling in more than one two-semester Flex course.
