This is my situation:

Gmat Score: I have been preparing it for some time, pretty sure i will get into the 700-730 range.

Work experience: I have been working in a small company (retail business) for 6 years. my title went from IT consultant, to Assistant GM, lastly to General manager. When i was in the management position, the business grew from 2 stores to 6 stores. The business also improved a lot in many other areas.

Undergrad GPA: 2.95, graduated from state U of new york with BS in computer science.

Target school: I am targeting MBA program in the 10-20 ranking. I really like McCombs (Texas), Darden (Virginia) , and cornell (NY).

MY Question:
As the subject stated, my salary is low. I just find out that i have to provide my salary information with the application. This makes me worry.

My starting salary was $20,000, and my ending annual salary is only $26,000. This is because the company just get started, and couldn't afford paying a lot to its employee. The owner offered me shares of the business as he promoted me. i didn't leave the company because i think the experience i got will be useful for my future career.

My concern is that,when my application is being reviewed, would they think that "this guy only making $26,000 a year as a general manager? There must be something wrong."

Is the low salary gonna be a problem? Is there somewhere in my application i can put a explanation about that? or maybe it is not necessary at all?

please give me some advices, THANKS!
