How to responsibly use Reorder Scripts?

So I installed the reorder script with the intention of making it so I don’t level up until I’ve cleared out my lessons more. I absolutely hate that I can’t go at my pace without leveling up and getting a huge backlog of lessons. I’d like to learn the kanji last to prevent this.
My question is will this work? Or am I gonna get vocab that I don’t know the kanji for?
Thanks!
