Nope! There's no need to commit to any particular schedule - the online classes are flexible, and are designed to work around your schedule. Live class modules are held regularly, and may be taken in any order. Our online class system automatically keeps track of your class progress.
If you'd like to take the topics in a particular order, the order that they are listed on your Dashboard is what we recommend, but there's no need to follow it. Feel free to take any class that works for your schedule, so long as you've completed its prerequisites!
