Query: Delmar's Pharmacy Technician Certfication Review

I HAD ANOTHER CERTIFICATION BOOK WHICH HAD A LOT OF WRONG ANSWERS & TYPO'S. THIS BOOK EXPLAINS EVERYTHING VERY SIMPLY & IN A LANGUAGE THAT IS EASLILY UNDERSTOOD. IT FOCUSES ON WHAT YOU NEED TO KNOW IN ALL AREAS & NOT A BUNCH OF INFORMATION THAT IS TRULY UNNECESSARY. ALSO IT COVER ENOUGH MATH HOPEFULLY TO GET YOU TO PAST THE TEST. I WOULD RECOMMEND THIS BOOK TO ANYONE STUDYING FOR THE PTCB EXAM.
