Strategy to grasp quant concepts

by ThiMBA » Mon Mar 08, 2010 11:29 am
Can anyone share their strategy for grasping quantitative concepts? I've been doing a lot of problem solving but I feel that has not helped me in terms of truly mastering concepts (number properties, algebra, geometry, probability, permutations) ... I usually go through a set of 100 problems and log them on a notebook and review it a week later but when taking a sample exam, I feel I still do not have total grasp of the material

I am a little skeptical of the notecards method since it is strictly a memorization exercise and it might not help you understand the concepts entirely

I've been studying from the material from Veritas and just purchased the OG 12 - is there any other material I should be focusing on?

Thanks for the help

I'm going through the Veritas materials now as well. I am just going through each book and not moving on from a book until I feel confident that I truly understand all of the concepts.

Great question, and I admire your commitment to thoroughly understanding these concepts!

One suggestion - try to get as much mileage as you can out of each question:

-Ask yourself how they could ask it slightly differently to make it a bit tougher. By doing this, you'll develop a deeper understanding of the concepts themselves, and learn to anticipate ways that the test will tweak familiar themes to make them more difficult.

-When you get to the end of a problem and don't fully understand why the rule worked, even if you got it right, see if you can prove the rule to yourself. We don't do that enough in life - just ask yourself "why?" when you perform a step that you know you're allowed to do but haven't ever thought about, and you can better understand the fundamentals behind it. When I took the test, I just about blanked on the rule for solving (x^y)^z - I was pretty sure you multiplied y and z, but couldn't completely talk myself out of the thought that, maybe, you're supposed to add them. Quickly, I proved it to myself using small numbers: (2^2)^3 would be 4^3, or 64. 64 = 2^6, and not 2^5, so I knew I had to multiply, not add. After the test, I broke it down further - x^2 is the same as x*x. And y^3 is y*y*y. So, (x^2)^3 is (xx)^3, or xx*xx*xx. It's six values of x multiplied together. If you prove some of these rules to yourself, you'll never forget them, because you know exactly why the rule is the way it is.

You may also want to note any concepts that you know haven't "clicked" yet and search for drills that are specific to those concepts. Purple Math (www.purplemath.com) has a lot of these for algebra concepts, and there are quite a few study resources online for K-12 students that will give you specific drills on, say, exponential equations, or coordinate geometry, or whatever the skills are. If you're not quite there on a concept or two, it's probably worth your while to spend some time on the concept itself before burning through GMAT problems. The Veritas Prep "Math Essentials" lesson gives you quite a bit of that kind of work, but you can always search for a little more.
