It is possible to attend usa business school without work experience

Well,work experience is something that has always been a factor that gives you edge over others when it comes to MBA programmes.It gives a sort of assurance that you have the required abilities that you can contribute to the learning environment of the institution. Most of the business schools of USA look for a work experience of 3-10 years.
Your work experience is not an important part of your application yet it makes huge difference.But you can make it to Business Schools with a stellar academic performance and an exceptional letter of recommendation.Plus,your GMAT scores matter a lot and for that you need to work really hard.It's also your interest and inquisitiveness that plays a big role.
Institutions like Havard Business school,Anderson School of Management(University of California),Marshal School of Business(University of South California),John Hopkins Carey Business School,Robert H Smith School of Business,Stern School of Business,Questrom School of Business.
All the business schools look for candidates that can contribute to their organisation in the most efficient way possible and you have to decide on how you can prove your worth.You have to have good GMAT scores besides exceptional academic records or work experience.
Hope this helps.
Good luck.
