Hello, I just recently took the PTCB Exam in Southern California. I studied all the math on this website (which is a great website) but unfortunately I failed. No worries, I'm looking forward to passing this time around. But, I was wondering if you could help me with the math i did see on the test it was mostly very long and confusing dosage calculations nothing to do with percentages just all grams and you know of anything on this website that get's more in depth with the ptcb like dosage calculation questions? thank you for all your help by the the site
