Thanks for clarifying Sudhir!
I think we should take
MGMAT Quant tests results with a pinch of salt. I found a similar question on
MGMAT forum and Stacey's answer to it:
https://www.manhattangmat.com/forums/mgm ... t1053.html I feel that there are both +ves and -ves of
MGMAT Quant test.
+ve is that it does prepare one for any tough problems on the real GMAT esp. if one's target is 750+ because at that level he/she will receive tough problems that most likely cannot be solved in ~2min and should be prepared to make an educated guess and move on. This will allow one to tackle the next question, which might be easier if the previous answer was wrong or even more tough if one got that right. And if it is the latter, then one needs to again try best to make an educated guess using ~1-2 mins and move on to keep the score at 750 level. So, in essence, I think it helps us to prepare well for such a situation.
-ve is that one is not able to do the question under timed condition (because questions require slightly length operation) and that deprives the experience of solving tough question in the real time and gain that learning (such as using method B if A is not working, trying diff things etc). There are many things to try out and learn from during a practice test and that is somehow blocked by having a tough question that is tough primarily due to multiple steps required and not due to conceptual foundation.
From what I have read on forums, you should be doing just fine on GMAT Prep and actual GMAT on quant.
