The Math For Nurses is very helpful. I use it to sppluement whatever I did in Pre-Algebra and will be doing in Beginning Algebra. In NY we take Regents exams in high school...I took Regents classes so I did take math, chemistry, biology, etc. But it's been 24 years since I've taken most of these classes! The books can be ordered on Amazon or from Barnes and Noble...just search Barrons Regents Review. I'll post questions should they arise.
