The best way to study for the TEAS is to actually buy the booklet. The first time I took the teas, I didn't use the actual booklet, just resources I found online. After not being satisfied with my score I went and bought the booklet and saw significant improvment in my score. Hope this helps!
I like to do home workouts as my "study breaks." Sometimes if I leave the house then I seem to have a harder time coming back to studying, so this works great for me!
