Be patient. Top MBAs are selective and they ask for candidates with a strong application and a good GMAT score. That is the way of assessing the motivation of the students. So it is not a short process. It might take months for you to write up great applications. MBAs mean a great deal of sacrifice both in terms of time and money and if you are not prepared to spend time to write a very convincing application, you may as well not take it up in the first place.
Assess your finances carefully. An MBA is here to help you, not to drain your savings. Many people make the mistake of spending all their savings on the project. Avoid this to the greatest extent possible. The best way to do that would be to involve your employer, your family who can help contribute to and support the project. Unfortunately, I did it on my own and created a big dent on my personal finances. Looking back, I believe that I should have involved my employer and worked more on my financing. Dr. Hubert Silly had informed me of the necessity of getting a sponsor but I was more interested in getting the MBA and ignored his advice in the beginning. So my advice is to start looking for finances while preparing for the GMAT. MBA Center does organize regular sessions on financing the MBA but I never paid heed to those sessions as I did not believe it was the right time yet. And when the time came, it was too late and I had to bear heavy loads.
Finally, utilize the vast industry experience that MBA Center possesses. I have many friends from Brussels who have worked with Dr. Hubert Silly and have been accepted to NYU, LBS, INSEAD, IE, etc., and no one doubts the quality of MBA Center services. MBA Center also has these sessions on financing which many applicants ignore, instead of focusing more on their expertise in GMAT, TOEFL and admission consulting and not on financial aid. My advice is, do not ignore this service that they provide. It could prove very helpful to you in the long run.
