The Final Climb: Quest for Q 50+ from Q47/48

Ok Guys, I am back with some update. I am done with the mgmat advanced quant including the 15 Sets( 150 X 700+ level questions)given at the end of the book . A must do for those scoring around 45 + and want to take their score to 49/50. The book discusses some advanced tactics and strategies which are very useful esp for the difficult questions. I won't recommend the book to those having current level below 45.
Took a gmatclub quant test M07 to gauge my performance and got 32 correct out of 37( with two silly mistakes) Also took MGMAT CAT-3 and scored 50 ( 10 errors), Though the errors are more but the questions thrown were mostly 700+ level questions with some of them as difficult as mgmat challenge problems. The assessment sheet of the test shows a good thing that from question number 12 onwards, the percentile didn't drop beyond 92 %.
So, the conclusion is that the advanced book has given the much needed push from 48 to 50 in MGMAT CATs. i just hope it works for the actual exam also.
Will be doing the jeff challenge sets now and hopefully these advanced tactics will be useful there also.
