One of the easiest guides I had a chance to own. Looking through it I realized that it's all mostly about remembering how to do fractions, material that can be easily learned first before learning medical math on dosages calculations.
The good news is I found a lot material to be broken down so that it's easier to understand what certain words mean, abbreviations, etc...
Then towards the end there is a test section, which is good for practicing what you already know and see if you remember anything.
I do enjoy the little cartoons floating around throughout the book making it a little more enjoyable and less boring for the eyes when having to read the material.
Overall a great little pocket guide for those going to enter into a nursing program, are taking a course in dosage calculations, or just need a refresher for the job.
