I have been intensively researching Business Schools and the MBA application process for about a month now and have found several resources that have helped get me pointed in the right direction.
1. MBA Podcaster
MBA Podcaster has built up a wealth of interviews, discussions, and guidance on every aspect of the MBA admissions process. It has helped me generate heuristics for part time vs full time, evaluating MBA ROI and performing self evaluations for getting into top schools along with a wealth of information. Each podcast tends to run between 15 to 25 minutes which is great for my commute. I just load them up on my Blackberry and listen to them on the way to work.
2. Clear Admit Blog
Clear Admit is an MBA Admissions Consultancy, but they have also compiled one of the most thorough resources on the web for information on top programs. Each time I begin to research a new school I read the full summaries and any available articles on the Clear Admit blog.
3. Stacy Blackman Consulting Blog
Stacy Blackman is another admissions consultancy, and their corresponding blog has a few great tools. Most notably there is an extensive section on essay tips for current essay questions from most top MBA programs.
4. Business Week MBA Insider
Most of the major financial publications have rankings and information on top business schools and MBA programs, but Business week does a great job getting info on specific school admissions and student profiles to help you narrow your search as well as determine your chances of getting in.
