True... but personally just reading material doesn't do anything for me... for example while i was in school i found it harder to retain much by just reading until i found my own way to learn!

unfortunately though instructors do teach the way that they want to and the way they are most comfortable with! for me i got lucky to have an instructor that taught me in a way that i would retain things!

i did after my certification maybe like a month or 2 later re-read my book! it was a good refresher... but in a way that yeah i remember doing that or being told!
