The Application Process

I did my masters in Biochemistry in kansas state and am planning to apply for my MBA this year. I just took my GMAT and scored a 680 and 5/6 in AWA.

I dont have any professional work experience but I do have 2 years of lab experience. I have a 8.1/10 in my undergraduate from one of the top schools in India. And I have a 3.8/4 in my Masters here.

And I was involved in both the Student Govt. and Indian Association here in K- State.

I was wondering if I really need to have some work experience before I start applying or should I go on and apply this year.

BTW, I am aiming to get into top-50 colleges.

Thanks
