Andy rdh shops book 2022

Product Name: Andy rdh shops book 2022
This is the only book I used to study for the hygiene boards and I passed on the first try! I traveled to the board review but was not able to attend any of shops the seminars due to an emergency, so I only studied from the book. It is an interactive book with QR codes to scan and had practice questions at the end of every section! I highly recommend this book for anyone about to take boards! 3 classmates and I traveled to the review and studied from Andy RDH and we were the only students to pass boards on the first try from our class!.
