Thoughts on MGMAT CAT vs. GMAT Prep CAT

Well, just to put my five cents in.

I had the same impression about the difficulty of the MGMAT quant part. Namely, that it is far more difficult than the GMAT Prep quant. And I agree with Shaselai - there are really tough probability & combinatorics questions. Frankly, I just can't imagine someone to crack some mgmat quant questions in 2 minutes.

My scores are (just for statistics, maybe it will be interesting for someone to compare):

710 (Q48, V39) GMAT Prep #1 - first test taken as a baseline without any preparation.
720 (Q44, V45) MGMAT #1 - after one month of preparation
720 (Q47, V41) MGMAT #2 - one week later.

The first result on GMATPrep was already good enough for me, the biggest problem was on SC in verbal - 8 errors (I'm not a native speaker )

I was quite puzzled while taking the first MGMAT by the difficulty of the quant section. It was after I worked over the Kaplan 800 where I had virtually no problem to solve any question in less than two minutes. So I tried to solve all the questions even if it took me additional time, and as a result had only 3 minutes to answer the last 8 questions (all wrong of course ) And I had some luck with the verbal part (V45 is too good for me).

So on the MGMAT #2 I made much more guessing in Q part to spare the time in the middle of the section and that payed out, but I still didn't reach my GMATPrep Q result. And once again, there were more than a couple of questions that I had absolutely no idea how to tackle.

Now I'm taking MGMAT #3 tomorrow and next Saturday GMATPrep #2. The real thing is on September 13. Hope that the difficulty level will be closer to the GMATPrep than to the MGMAT!

I think you have a very good shot at 750+ on the real thing. I had a very similar experience with my prep - I was maxing out at 720 on the MGMAT tests but got 770's on my 2 GMAT preps and 770 on the actual verbal... I agree with you on MGMAT verbal - I think the best way to describe a lot of them is "sloppy".

I agree with you on MGMAT verbal. Its like they worked on making the the answers elusive . Sometimes I found their CR questions and the answer explanations iffy and subjective.

Next test I'll do will be a GMAT prep. I also find that some MGMAT quant questions are just crazy and drain all my energy to finally fail on the answer.

Upgrade after the real test taken:

GMATPrep #1: 710 Q48 V39 (baseline test, without any preparation)
MGMAT #1: 720 Q44 V45 (after two Kaplan books)
MGMAT #2: 720 Q47 V41
MGMAT #3: 730 Q49 V41 (after Number properties MGMAT book)
GMATPrep #2: 760 Q50 V43

Real test: 740 Q48 V44

So, my conclusion that the overall difficulty of the Real test is somewhere in-between the GMATPrep and MGMAT.

I had the same feeling about the MGMAt verbal part as you !!
The gmatprep is the most accurate predictor, therefore dont worry about your lower scores on the MGMAT
Hope you will ace the GMAT

Please HELP.. !!!!

I took Kaplan CAT last week and scored a 690. (99% quant , 66% verbal)

Yesterday, I took MGMAT CAT 1 and god knows wat happened, I ended up with a 530 (quant tough and some stupid mistakes).
Does the real GMAT have quant of this level ? Verbal was easy but made my silly mistakes as I had lost my cool after seeing Quant. I am bogged down depressed and out. My GMAT is a month away and this is the disparity in my scores.

I am yet to take a GMAT prep test.

Which test score is a better picture?

Please help as I am absolutely clueless.

Thanks,
Azal

Azal welcome to the gmatclub.

690 on Kaplan is a great score as those tests are considered tough. I'll suggest you to take one more practice test before commenting further as 530 -690 is a big range so to judge your status go for one gmatprep CAT. Also, with gmatprep you will come to know about the difficulty level of questions.

Also, don't be disheartened as you have 1 month left and still you can reach 700+.

Keep us update about your progress.

I have a similar concern. I completed Princeton review guide about 4 weeks ago and took my first GMATPrep CAT. I scored a 690 (44Q, 40V). I was was happy with this result because it was early in the process. I then proceeded to the OG 12. I worked every Quant problem. I took the GMATPrep 2 and scored 690 again with the same breakdown. I realize now ( after joining the gmatclub) that this was a waste. I then decided to buy the MGMAT series. I went through FDP and found it helpful. I took MGMAT CAT 1 last night to use as a diagnostic. I scored a 640 (Q43, V32). I am extremely disappointed. Is there apossible explan ation for this drop?

Where do I go from here? Do I stick with my self prep MGMAT plan or do I consider a prep course?

Please help. I am very discouraged.

There is nothing to be discouraged. Only GMATPrep will be the best indicator of how you will perform on your actual tests. The other tests are helpful to identify your strength and weaknesses, improve testing experience and stamina. While MGMAT quant is tougher (in terms of time consumption unlike GMAT traps) than actual GMAT questions, the verbal part is not that good. Verbal questions are more biased towards the strategies provided in the MGMAT guides. So you don't need to worry about MGMAT scores as long as you are doing fine in GMAT prep. A V40 in GMATPrep is a great score close to 90 percentile. You can use the tests to improve your quant performance, testing experience and stamina. Don't bother about the MGMAT verbal scores. I never crossed V30 in MGMAT but scored a V35 in actual test. A prep course will be of no use to you. You are already close to 80%ile in both the sections and you have to start from scratch in a prep course. Instead focus on using the MGMAT tests to identify your strong and weak areas (best thing about MGMAT tests - reports) and work them to achieve your target score.

Thanks for your help. Is there any point in taking the GMATPrep CATs again before my test date (after MGMAT Prep) or will I a lot of the same questions and receive an inflated score? I decided after my GMATPrep CATs that I should just focus on the Quant from MGMAT, but after I took the MGMAT CAT I started questioning my Verbal as well. Would you recommend going over the Verbal books from MGMAT as well? I am planning to at least cover the SC book.

Sorry to ask so many questions, but this is my only source of GMAT insight. Do you have any specific recommendations on how to review the CATs? Do I just need to go through them slowly and thoroughly and cover all questions?

Thanks again!

GMATPrep tests can be used any number of times. After 2 or 3 times, you will get many repeated questions, but till then you will see around 4 repeat questions at the max. Inflated scores is directly proportional to number of repeat questions you encounter. Preparing for verbal is your call. You can concentrate on your quant instead of verbal. While some schools expect a even split around 80%ile in both, some doesn't. Choose your schools and target score, find out how much split you need to score then focus on the section which has more gap for improvement and which is easier for you to improve in a short time. You are already in 90th%ile in verbal and if you find it easier to improve then go for it, else work on quant to make it even. As for the books, you can try MGMAT SC if you are weak in SC.

It takes a whole day to review the CATs. Don't finish your review with explanations from the CATs, start by looking for posts with different explanations. If you don't understand any explanation, post your query and clear your doubts or use the books if possible to clear them. Try to find the shortest, easiest method you can solve a problem. There is always a better method to solve a problem. Take notes, error log. It takes from 5 mins to 10 mins to review a single problem. You can check this link as well. Got loads of tips from Stacey, a GMAT expert, - https://www.manhattangmat.com/articles/ - includes articles of how to review each type of question, analysis of practice tests etc. Hope this helps !!

I took a GMAT Prep Exam two weeks ago and scored a 650 (q-49, v-30). Today I took a MGMAT Quant and scored a 660 (q-45, v-35). The overall scores are really close. But, the percentiles for the Verbal and Quant are really different. I definitely agree that the Quant on MGMAT was more advanced. But, I wouldn't say they were "harder" from a conceptual persepctive, they just required more steps and calculations. GMAT Prep Quant questions could be answered in fewer steps and in fewer calculations. I thought the RC questions for GMAT Prep were slightly more difficult, but I thought that the MGMAT articles were longer (and therefore took more time to search for the detail questions). I thought it was odd that I got 19 wrong on GMAT Prep Verbal (but, I will say that I got 11 in a row wrong in the middle of the test...so that may have played somewhat of an impact form a percentile perspective) and received a 30, while I got 17 wrong and received a 35 (with no more than 3 or 4 in a row wrong as the longest "incorrect streak") for MGMAT. I know the GMAT is not about number right over number wrong. But, a 5 point swing over two questions seems pretty broad. If anyone has any feedback, I would really appreciate it.

I completely agree that the test score discrepancy looks a little bit weird... but it's not unusual at all.

Anybody who knows me is probably sick of hearing this, but here it comes, anyway: non-official tests (anything besides the GMATPrep) are inherently unreliable, at least to some extent. MGMAT's tests are the work of some very smart people who are trying their best to reverse-engineer the actual GMAT test... but MGMAT's tests just aren't the same as the real thing. MGMAT's tests differ from the actual exam in all sorts of subtle ways (some of which you mentioned in your post, jppaa), and it isn't unusual to see huge discrepancies between MGMAT tests and GMATPrep. A 5-point gap on each section isn't crazy at all.



I think you're exactly right with this stuff, and these are the sorts of things that can bias your score on the MGMAT tests. I think MGMAT does a phenomenal job with all of their materials, but it's unbelievably difficult to replicate the GMAT, and it's always wise to take your MGMAT scores (or scores from any other practice test, besides the GMATPrep) with a huge grain of salt.

My hunch is that you got caught up in the details on some of the MGMAT quant questions, and that probably biased your score downwards. (Maybe you spent more than three minutes on a few MGMAT questions, and then rushed into errors on a few other questions?) On the verbal, it's less clear why your score would be higher on the MGMAT tests--maybe you've used their materials heavily, and you're accustomed to their writing style and verbal traps?

In any case, I would take the GMATPrep result much more seriously as a diagnostic, and it looks like you might want to spend some extra time on verbal in the coming weeks.

And for what it's worth, it also isn't strange for two questions to make a 5-point difference in your score. It's all about which questions you miss, not how many you miss. You could miss 15-17 quant questions and still get a 47; you could also miss 15-17 quant questions and barely score a 30. It's just a question of which questions you miss, and where they fall in the exam.

I hope this helps. Good luck with your studies, jppaa!

GMAT Ninja,

Thanks for your help. You are right about one assumption: I would spend too much time on a particular question (4 minutes in two, separate cases), and rush to make up for lost time. I was sucked in because I "knew" how to answer the question. But, I would begin to calculate, solve it, and get it right. Or, I would begin to calculate, get frustrated, guess, and move on. In most GMAT Quant questions, there is some kind of underlying "trick" or detailed knowledge (e.g. knowing odds/evens relationships, knowing exponent patterns, knowing prime factorizations) that is required to quickly solve a somewhat convoluted or "scary" looking problem. But, some of these really difficult MGMAT problems would require the tedious exercise of evaluating answer choices by plugging them into several equations. As far as being used to "MGMAT's style", I purchased MGMAT SC (and Advanced Quant, which isn't relavent to the verbal), and that is it. Not a ton of exposure to MGMAT's style other than what has come up in CATs. Let me know if you have any additional thoughts.

The GMAT Prep CATs are the real thing. MGMAT CATs are the next best thing. I wouldn't try any other CAT.

MGMAT CATs are mindblowing. The Q questions are def a little harder, but if you've practised enough there will be zero questions you will not be able to tackle. They make you think in the right direction - by far the most important thing on the GMAT.

Strongly recommend MGMAT CATs to everyone.

My scores : 680,670,680,670,690.
Final : 700. (Was a sure shot 730 had i not missed that one V question)

PS : Had time to spare on the Q section. (After reviewing each question twice!)
ALL THANKS TO MGMAT!
