Days: Monday-Thursday (not all students have 4 days of classes)

You can also bring your personal laptop or device, connect to the MDHS network (MDUSD-Student-Personal) using your student e-mail credentials, and if necessary, download the appropriate certificate from the District website so you can access the network. 

A student either comes to school Monday and Wednesday OR Tuesday and Thursday. If they have two different subjects, they will be at school from Monday through Thursday. Letters have been sent out to students explaining their schedules, and summer school class information can also be viewed on Homelink.
