A must before the real exam

Not only the quality and variety of questions included is great but also the analytics which comes with it post taking a test. It has a large database of 700+ questions and in all likelihood, even if you don't get to see the exact question in the real exam, by the time you would have attempted and analyzed the questions available, your mind would have already been trained strenuously to think of different tricks the test makers can put in the exam and this will help you vastly improve your performance.
The best strategy I would advise is to take a 75 min test and spend about 2-3 hrs analyzing each tests. Look from the perspective of timing, concepts knowledge, pacing etc. This way, you will maximize your leaning and your score also which will be a big confidence booster for the real exam.
I will recommend them to any serious test taker and the best part is they are available as a bundle with many other online courses making them really cost effective.
