STUDIES
Equipment Maintenance & Repair
This was a difficult section for me to study. I feel like the best way to get through this sections is to do some hard core memorization. I have included some tables. I know that a lot of times when I see a table in a book I just skip is, but treat this table like a check list of things to know. Make sure you can identified the instruments you are required to identify and know how to clean those instruments. Good Luck!
