LABEX.io and how to incorporate it with your study routine

I just started my adventures of studying for the RHCSA ex200. I’d say my skills right now are ok, I built my own VMs for my home lab and I’m using the GOAT’s(Sander Van Vugt) cert guide book and videos to study. I recently subscribed to Labex.io to use it as an extra study material for my studies but I was wondering if anybody has used it and what their experience was like. If you care to share what methods did you use to incorporate Labex to your study routine - that would be awesome. Thank you in advance.
