The forum is a great resource, here is my $.02:
Spend a couple hours and sift through some of the sticky threads and starter guides on here.
- Build a strategy to your prep
- Assemble the resources you will need
I have studied on and off over the past couple of years. I have used books, tutors, and now the Economist
GMAT prep software. It probably depends on how you learn and your focus. From my experience, the GMAT prep software I'm using has made more of an impact. It is convenient, well structured, self-paced, and works a lot on the approach/process/and strategy of the test. I find this more helpful than the rest. I had a lot of quant deficiencies because I never learned algebra that well in high school. I found it took me a long time to really understand the fundamentals but once I did and started grasping the in and outs of the exam, I really started building momentum.
I'm just now at the practice test taking phase where I will score and hone in on my weaknesses. Most of my upfront focus has been working on the fundamentals and understanding the test. The good thing I did was keep a note pad of things that I was having more issues with. This helps when I have time to open a book (get a different perspective) or work with a tutor.
I'm no expert, just trying to prep myself. Like anything, set a goal, a strategy, and measure. Good luck!
