Back from Denver - 2nd Post - GMAT Preparation

Well I managed to leave Denver before the snow could derail my travel plans. In Denver the weather is weird, I mean on Wednesday (01/10/2007) afternoon the temperature reached nearly 65 F and on Thursday evening it was around 10 F and it was going downhill.... What a temperature swing!!! In Denver I had a huge meeting with some C level execs of a major Telco, and it was a great experience answering business and technical questions coming from different angles. Honestly after these meetings the B-schools interviews feel much more relaxed..
Well I will devote this post to my GMAT preparation, I started my GMAT preparation on Jan 3rd 2006, it was a new year pledge. I decided to take the Princeton online course, I felt that it will force me to regularly prepare considering the amount of money I had to pay. The Princeton online course had some very useful Math tips, but I felt the verbal part was weak. On the whole with their practice tests and the lessons it was a good experience. Although I must say their AWA evaluation is out of whack I used to get 2-3 on my AWA essays.. However my preparation was interrupted by several business trips to Toronto, Montreal and Tampa... As with any business trip you hardly get time for yourself with business dinners after work, so I decided to start studying in the airports and airplanes. It was initially tough, but then I got used to solving some Math problems in the airplane and that would attract stares from my neighboring passengers. From the Princeton online tests I identified my Achilles heel was Sentence Correction and so I focused on that.
However,I realized that I should spend time on the Official Guides, so I bought the Official Guide plus the Official Math and Official Verbal guides. And then it was all about solving the questions in the Official Guides, with special emphasis on Sentence Correction. I made some flash cards to keep revising the key grammar concepts (It really helped a lot). Bottom line there is no substitute for the Official Guide, it is the best material for the exam.
Before the test, I took the simulated tests available free from the GMAT website, I also purchases some paper tests from the GMAT website. The simulated tests were very useful and I felt adequately prepared for the actual test.
