This company gives access to their content for a subscription, so you pay as long as it takes to complete the preparation. This is fine, however, after the first purchase period (30 or 90 days) they will send renewal emails to ask you to renew your subscription or you will lose all of your progress and there could be delays in regaining access. To avoid this, they tell you to renew before the deadline, however, I did this and still got access revoked and it is impossible to reach anyone for assistance. Additionally, they label their preparation as "high-quality", yet, most of their content contains major grammar errors, asks questions that are not even answerable, and answer choices that do not align with the question being asked. While most of the actual information provided is accurate, the test prep part (the most important part) contains frequent flaws. I strongly recommend ANY other Test Prep service provided. read more
