I just signed up to take my upgrade exam as well (licensed to certified)... I've purchased the practice exam question testing through AI and also purchased the Student Handbook (14th edition) to prepare. In all honesty, a lot of the practice questions don't seem to be too tough and I've done pretty well without reviewing any content yet. I'm hoping its not a fluke! Does anyone know how much math or statistical questions are on the AR exam? I'm pretty concerned because statistics, income caps, etc aren't my strong point. I'm scheduled to take it next week, it's coming up quickly!
