Have trouble with medical math no more
Format: Paperback
Best medical math book ever! It gives how to do each problem multiple ways and makes it easier to learn. This book is amazing! This book makes math easy even for me, and I do not like math at all and that should sum up how great this book is

Weird wording questions

Very weird wording with the math problems. It doesn’t really correlate with test questions or board exams.
