Hi-

I am having some trouble with geometry. In general, once I look at the solutions I realise I have made silly mistake. (I know it is a shame, particularly because I am from a Comp.sc background and was very good at Math in school). My main problem is that I tend to forget simple things like:
"If a squareis inscribed in a circle, then the length of each arc created by the square is equal".
simple things like these! I knew it as soon as I looked at the solution, but I was wondering if there is some place I can read and refresh all the geometry concepts for GMAT? Also, does anyone have experience with MGMAT Geometry guide?

I know, to get a good GMAT score, I will HAVE to do well on quant, and I can not afford to do average there. For this reason, I am looking for resources/suggestions on how to tackle this problem.

The best thing would be to search and learn the geometry basics from some websites. The stuff tested in GMAT is not very difficult but its about application:
1. May be a combination of geometry principles and algebra
2. OR finding a limiting case. For e.g, a rectangle with largest area that can be inscribed in a circle is a square.

I had a question on my test that required application of number properties to find multiple values of a variable (for eg size of a square) and reject one solution since it violated a boundary condition... you get the idea right.

So don't sweat too much on learning complex geometry properties. Focus on the application type questions. OG and GMATPrep have some good ones.

And the fact that you are a Comp. Sc Engineer doesn't necessarily mean you will get great Quant score without any effort. You need to get your hands dirty if you want to work in a field. I have found it the hard way. I am an Electrical Engineer and I always scored 90-100% in all of my math classes, somehow managed to get a 50 in Quant, but I still get stumped by some of the difficult DS and probability/combination/statistics questions posted here.

So put your Ego behiend and solve as may problems as you can. Pay special attention to the GMATPrep ones and more importantly work on your weaknesses.

Good luck!

Thanks Giddi-

Just to be clear, I have no ego with working on Quant. The fact that I identified my weakness in Geometry says that I am not being over-confident here.

OG and GmatPrep are great for practice, but I wanted something to just revise my basic concepts. Any experience with MGMAT Geometry guide, or any other resources? There are TONS of resources on the Internet, but I do not find anything good specifically for gmat.

Thanks,

I just received my MGMAT geometry guide... I am using it to work on my basics. I feel that it was good as a central resource to brush up everything you might need on the GMAT and provide a way to classify the OG11 problems based on the area.

Dude, sorry if I sounded like an idiot. I definitely had an ego problem when I started GMAT prep and I thought that Quant would be a cakewalk for me, but that was not the case at all

Here are a few Geometry links (The links posted below have way more information that you would need to tackle GMAT geometry problems.. just study the basics...)
