Sorry if you found some lessons difficult...
What exactly did you think was difficult and advanced?
It's possible that the method and style of lessons are different from classroom lessons,
so it can be "fast" and/or "casual". It's normal if you feel some differences.
If you have some knowledge already, you can of course start from the beginner or even upper level.
However, in terms of "getting used to the lesson style", you can also start from the lower level than
your actual level. You probably know all those lower levels' grammar, so you can forcus on expressions
and practices.
Please remember that you're always welcome to ask us any questions on lesson comment board
We're happy to help you!
Hope you'll enjoy our lessons.
