Lesson is rated 2500. But it seems TOO easy for 2500. Perhaps this is a mistake
I tried it. It was too hard for me. I know that doesn't mean anything.
It's hard to tell from your profile if you are a too-humble GM showing off your mad skillz or just some 1300 rated guy with a computer.
The reason I can't tell is because you haven't played any rated games here on Chess.com. You did play 5 unrated blitz games and if the 5 unrated games you played (with 4 losses and 1 win over a guy rated 1353) had been rated, your rating would be well shy of a 2500 level, perhaps well below 1500.
Still, if those lessons really are that easy for you, why not start tearing the place up?
