Is FluentU or Yoyo Chinese good for continuing learning Chinese after high school?

I had Chinese classes for three years in high school, which I loved, so I’m trying to continue learning the language. I’m not sure what my level is in hsk terms, as I can recognise words and grammar from level 1-3, but not all. But I did pretty well in classes, and I feel bored by platforms where you start from scratch again.

I’ve been using Duolingo temporarily for a few months, which of course doesn’t help much, so now I’m finally trying to find something new. I’ve heard good things about FluentU and Yoyo Chinese, so I just wanted to ask if anyone has had any experience with these platforms? And if its possible to start a bit above beginner level?
