The main menu is well organized, allowing teachers to pick and choose which lessen they want to cover.

Rather than relying on accuracy and speed, these models focus on comprehension and do not have any timed exercises. Allowing students to work at their own pace ensures that students are provided the opportunity to internalize the information.

It is difficult to view and access all the possible elements necessary needed to complete any given structure
