Nice Supplemental Resource
Theses tests were affordable and allowed for more practice in conjunction with the AAMC resources (which are an absolute MUST). I ended up scoring 7 points higher on the real exam than I did on the next step tests, but take that with a grain of salt in my opinion. NS Chem/Phys was more challenging with longer calculations than AAMC prep. NS Psych/Soc was fairly helpful at exposing you to new terms. NS CARS was not too comparable but good reading practice nonetheless (I recommend AAMC Q bank). Overall, it is worth incorporating NS tests as ONE of the tools in your MCAT prep toolbox, especially considering the price.
