No. All of our classes are a group class. You can jump right into any existing classes. Let’s think of one example. You are level 1 based upon the self-assessment test and you want to start taking a class right away. The only class you can join is at 9 am on Thursdays and the students taking that class are at unit 8 out of 14 units. It is perfectly fine for you to join them. Why? Because unit 8 doesn’t necessarily mean that it is much more difficult that unit 1, so you can actually study any unit. (Book2 is more difficult that book1, though) Besides, you will be able to find a class that will start from the very first unit in the future. If not, we will help you to cover all the units that you have not studied:units 1-8. Getting started with a lesson as early as possible is important with your Korean language journey!
