There are grade level requirements for Learning Support classes, and, in some cases, students do need to be a certain age before enrolling. (Details can be found in the course catalog, located on the Family Site.) All students must be able to keep up with the pace of the class and do a week's worth of work per week.
Most Latin and math classes require students to show proficiency in the previous level of the subject, either through an entrance assessment or some other means. In some writing classes, students may be asked to provide a writing sample. There are also some technical requirements. (See here for more information.)
Students in the Special Services Learning Support cohorts must receive permission from firstname.lastname@example.org.
Further, MODG requests that each student have their own email address, so that they can be set up with an Adobe Connect account to attend their classes.
