Wanted to share my thoughts on this topic in case anyone out there is using the
MGMAT CATs to gauge their progress and becoming increasingly frustrated as their scores aren't reflecting the effort being put in. I was in the same boat a few months back before taking my GMAT and a few Google searches pointed me to this helpful, but not exactly definitive, thread. I suppose this all differs based on the test taker, but in my experience the
MGMAT CATs are absolutely more difficult than the real thing, and by a fairly large margin, especially on quant.
Before I had opened any of the
MGMAT study guides, or the
OG, I took my free GMAT CAT exam. I ended up with a 630, which is a good starting point, but my quant score was a 37. After directing most of my study time toward quant, including going through the
MGMAT guides (post isn't meant to slam
MGMAT- these are helpful), as well as the
OG quant problems over the course of 3-4 months, I tried another
MGMAT CAT. This time I scored a 660. Not a bad score, but did not reflect how much time I had put into the study guides, or how well I was doing on the practice problems in the
OG. Figuring that my latest CAT was just a result of a bad day, I tried another--660. Went back and reviewed my exam, studied up on some things I missed, and tried another--660 again, with hardly any improvement in quant.
At that point I went looking for answers; my scores on
MGMAT just were not meshing with how well I felt I was doing on the
OG problems. I found this thread, and figured the GMAT Prep exams were worth a shot, really hoping that everyone on here saying that the
MGMAT exams were more difficult than the real thing were correct; fortunately,I found they were correct. After doing nothing but review my latest CAT exam, I took a GMAT Prep exam and immediately saw my score go up 50 points to a 710, including a 4 point bump over my best
MGMAT CAT quant performance.
If I could do it again, I would still do a couple of the
MGMAT CAT exams, but only to get the pacing of the test down. The
MGMAT CATs are a great way to learn how to save time by just moving on if you don't grasp the concept of a question immediately, or struggle on computation. With that said, the reason that they are so good for that purpose (which is very important, don't get me wrong) is because the questions require you to do that time and time again due to muddled concepts and multiple step computations. I found that the quant questions on the actual exam (and in the
OG/GMAT Prep exams) were MUCH more straight forward, and typically only required a single step computation. Clear concepts, quick computations.
In conclusion (to summarize all of this rambling)--Before allowing yourself to lose confidence or get frustrated by
MGMAT scores, take a GMAT prep exam. In my experience they are MUCH easier (on quant especially...I found verbal pretty similar on both), and much more in line with what you'll experience, and the scores you'll receive, on the big day. Good luck to all!
