The short answer is no, and here's why:
There are many third-party practice tests out there, but only NCARB provides true practice tests, which you should definitely use. Third-party practice tests are question and answer, dressed up in a test-like format. The benefit comes if they provide clear and accurate explanations, which is what makes them a learning and recall tool.
At CLARE, we use a different approach to help you learn, understand and synthesize information. If you are studying to pass the ARE, you are in the right place.
