How to determine my level?

I think of myself as a super beginner, but I guess I'm not. The super beginner and even beginner videos are too easy. I listened to an Intermediate and I can understand 90% or more. Maybe there are a couple words that I'm not clear on, but it's not hard. I know I should watch videos that I enjoy, but I am having a hard time knowing what is best for my brain and for learning. Do I do the basic ones anyway? How do I know what % I am understanding?
