Each semester consists of 16 units. Four semesters (101, 102, 201, 202, 301, 302).
Each unit is meant to be taken in one week (you can take it whenever you want in that week, adjust the pace to your own work/school time).
Students can spend their time on learning the language instead of learning of how to work the computer.
Units are not bound to time or place, you can use PC or mac, tablet or smartphone. Internet connectivity is neccessary.
