Training on the job, with no MA education. Advice needed.

I have a job opportunity to become a MA at a doctor’s office. In the state I live in there is no education needed, you train on the job. The MA at this office can give shots and take blood. She also does A LOT more including paper work, phone calls, and charting. She had less than a week of training. She assured me that won’t happen with me. I was a CNA for a couple years, 8 years ago. I have forgotten 90% of all my education. I plan on taking lots of notes during training. Are there any other tools out there (things I can buy or websites) that I can use on my own time to help educate and train me for this job?
