Register for MBX Summer School

MB/X implemented a new payment/registration system in 2017. If you have made a payment or registered for classes using this system, please login using your account credentials. If you do not have an account, you will need to create an ACTIVE Net account in the name of an adult family member. You then add a child to your account during the registration process. You may complete this step prior to the first day of registration and peruse courses.

Create an Active Net Account

Registration is complete when you create an account, register and pay for a class.

Please note that creating a “WISH LIST” does not equate to registering for a class or save a spot in the class. You must register and pay for the course to secure a spot.

Dear High School Student,

MBX is pleased to present our exceptional Summer School and MBX Flex program. If you have already participated in our program, you are aware that we provide an outstanding educational experience: quality instructors who will help you to advance to the next level of your high school career, whether you are repeating a class, seeking enrichment or hoping to accelerate academically. If you are new to our program, be prepared for a productive summer. At MBX, we care about the success of our students and we will do our utmost to help you succeed.

Please take some time to review all information carefully. For traditional MBX Summer School, we utilize a Semester format for Academic classes. The first three weeks of Summer School will be the first semester and the second three weeks will be the second semester.

Classes will be from 8:00 AM to 1:30 PM for three weeks with two 15 minutes breaks for nutrition.

A year-long class (two semesters) will also be held according to the schedule noted above from 8:00 AM to 1:30 PM but for 6 weeks. You must register for both semesters.

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 certificated teachers for approximately 20, 2-hour block sessions for 2 semester courses and 10, 2-hour block sessions for 1 semester classes, plus proctored tests, with the option of 1:1, 1:2, or 1:3 teacher/student ratios. Like all MBX Summer School courses, MBX Flex is WASC accredited and is accepted for credit on MCHS transcripts.

We want to take this opportunity to thank you for selecting MBX. We look forward to working with you to reach your summer academic goals – an integral part of the MBX mission. Should you have any questions or concerns, please do not hesitate to contact us.

Dr. Karina Gerger
Principal, MBX Summer School
