The concept is amazing! I saw my classmate using this for boards (NPLEX)and I decided to get it. I only used it a few times though and never picked it up again because I suck at memorizing and prefer to just learn it the old school way. It’s cool if coloring is how you study. Maybe using it to wind down from an intense study session.
