Students take four courses, around 90 minutes in length, every day for the first semester and take four different courses every day for the second semester. This results in a full eight courses taken per year.<ref name=":0" /><ref name=":1" />
A method called 4×4 block scheduling splits the academic year into quarters, and uses a four-period day.<ref>{{cite web|url=http://www.internet-high.com/4x4/may93.zip|title=Organizing a World Class High School|author=Clarence M.

The 4×4 method is somewhat more flexible in that students can take two sequential classes (such as Algebra 1 and 2) in the same semester (in different quarters), which would not be possible on a traditional schedule. This also allows students in their final year to fail a third-quarter class but repeat it in the fourth quarter in order to graduate.
