Thanks for the interest in our Simulator software V. Chornyy, I’ll do my best to answer your queries:
1) There are approximately 150 questions in each question set that are arranged on a Bell Curve to insure that the question selection algorithm has enough questions of each difficulty to accurately isolate your performance level.
2) Our exams are best used when the student treats our simulated exam as if it were the real exam and completes every part under realistic conditions with no breaks or distractions. Our exams are not designed for practicing specific question types or for drills. Instead, they offer students the opportunity to simulate the real exam and practice handling the rigors of the exam experience in combination with the challenges of the questions themselves.
Tutors typically offer one of our exams to a student to find a baseline performance level, then they design a course of study for the student. Some offer a second exam mid-way through the course, but others save the remaining four until the end of the course. Your preference will depend on your current performance level and your goals.
We typically recommend that you complete all the study and drills you intend to perform for GMAT preparation Afterwards schedule time to complete our exam as if it were the real thing. If you score in your desired range on two of our exams, you should feel confident that you have met your goal and sit for the real GMAT asap. If not, then address your weaknesses with more drilling or professional assistance.
In other words, you may only need two or three of our exams. In fact, we originally only sold three for this reason. However, as competition for higher scores grew, many of our customers felt three was insufficient and demanded additional simulations so we released two more exams bringing our total to five we offer today.
3) We have found that the best resource for specific problem-type drilling is the
Official Guide for GMAT Review. We highly recommend it as a core study aid for all our prospective MBA students.
