Awesome post BB !
I'd like to add a few points to what you said ( though this is probably more for people trying to go from Q47/48 to Q50) :
1) I'd say first and foremost go through the
MGMAT guides and get a solid footing ( yes , even if you're at Q48 you can still pick up a number of new tricks from these books)
I see many people recommending the "Advanced
MGMAT quant " book . I personally don't think this book is necessary , I never went through this book and I still managed to get a Q50.
2) ALWAYS and I mean ALWAYS have a stopwatch with you when you are working out problems ( even if you're just practicing) . This will help you immensely ; you need to get into the mindset of finding the quickest possible solution . There's not much use in learning a time consuming method ( especially for mid-level problems) .
3) The
OG Questions unfortunately aren't too difficult for people striving for a Q50 . You should do the questions as you are doing the
MGMAT quant guides . I'd really recommend that people don't refer to the
OG explanations for any of the questions . If you follow these explanations , you'll take forever to finish the quant section !
I'd highly recommend you look at Bunuel's post on these forums for more precise/efficient solutions .
4)If you need help with specific areas , i'd recommend you check out this link :

1)Do all the
MGMAT question banks and make sure you review all the
MGMAT CAT questions that you get . I love these questions , they are just so challenging and they push you to your limits . Don't get too disheartened by your quant score on these tests , just try to learn how to solve the questions you see there .
2)Do as many
GMATCLUB tests as you can , these tests are the golden standard for excellence as far as the quant section is considered !
3) If you want a top score in the quant section , you need to brush up on Probability/permutation& Combinations . I have a feeling you'll see atleast 3-4 questions from these topics as you reach for the upper levels .
Extra tips :
1)Don't "fall in love" with any question !
. No question is worth more than say 3 minutes . At the 3 minute mark , just guess and move on .
2)Don't fall for the trap for taking extra time for the first 10 questions . Yes , the first 10 questions are very important , but it's a bad strategy to take more than 20 minutes for the first 10 questions . If you take too long for the lower level/mid level first 10 questions , then you'll have lesser time for the remaining 27 Upper level questions .
So in effect you will be taking more time to answer easy questions and taking less time to answer more difficult questions !
Of course I don't mean to suggest that you should rush through the first 10 questions ! Not at all ! You have to try to be careful without wasting too much time .
Good luck everyone !
