Tips for GMAT success in 21 days....
This is a little off the usual topic, but I recently studied to sit my GMAT exam to go to Business school. I figured an MBA on top of the music experience is a good move for the career!
Anyway, I came across some great links on the material I needed to revise and they helped. Here are my tips and suggestions.
Week 1 - Slowly revise basics using Kaplan pocket reference.
Week 2 - Do questions including a “slow” diagnostic test to see the challenge
Week 3 - Start sitting timed exams every day or two and solving unsolved questions until understanding why COMPLETELY!
In my final week I used the 2 FREE GMAT.com tests and the Kaplan free test. I took one GMAT one day, another the following day, then took 2 days to review what was weak before sitting the Kaplan test online.
This method saw my GMAT score rise each test and the 600+ score I got on my actual GMAT was the same I got on the final Kaplan practice test for what its worth!
Commit certain things to memory
Triangle ratios (Pythagorean Triplets) starting at 3-4-5 up to 9-40-41
Squares up to 20x20 (and even 25x25)
Pythagorean Triplets - Amazing trick
How to treat ‘powers’ and ‘roots’ (VERY IMPORTANT)
To check which multiplication tables were weak, I wrote out a grid of my tables and circled any that I had trouble with and discovered my 9 and 12 times tables were a little rusty, so for 2 weeks I randomly challenged myself to remember them until they were as fluid as the rest.
The books I worked with were
Kaplan GMAT pocket reference
Kaplan GMAT 2016 Strategies, Practice, and Review
The Kaplan book with “Strategies and Review” was fantastic to help get me up to speed and when I was through with it, the GMAT Review was a great second read to refresh what I had been doing and to give some new perspectives.
I used several online resources during my study:
GMAT - The Art of Guessing
Mastering the GMAT Math Section
Mastering the GMAT Verbal Section
Isosceles Right Triangles (VERY IMPORTANT)
Some great Basic Maths Quizzes
Some great Maths Skills Practice
Some Great Basic Maths Courses

Mutually exclusive events cannot happen at the same time.
Combinations and Permutations
