Hard to evaluate with so little info on your profile, but in general it does indeed help to be in top 5 or 10% of your class. Having said that, if you can present compelling reasons why your marks were below par, show an upward trend in your grades over time and post a good GMAT score, you can certainly "make up for" not graduating in the top of your class. Also it matters where you went to school and what courses you took. A bad
GPA alone will not normally get you dropped, but failing to convince the adcom that you are fully capable of handling the program and digesting all the information is catastrophic. good GMAT can really help here.

Thankyou so much. My profile goes like this. Let me know whether I do have a good chance or not. I would be very grateful for your honest opinion.

Schooling - 87%
U.G.- 69.3%
Work ex- 2 years as of now and by next sep it will be 3
I work with the church for a lot of missions, teach children every sunday, Every Saturday I work with kids rescued from Brothal and other than all these I go with a team to Orphanages, homes and juvenile houses!!! I have done a lot of stage plays and dramas. But I dont have any certificates to prove them. What do you think????

The schools you choose will make a difference. Top schools are getting more and more competitve with the bad economy and upward trend in post-MBA salary. What I like about your profile is the level of community involvement, which is important and demonstrates depth, passion and maturity. Again, if you are trying to overcome poor undergraduate record, i would focus on achievements on the job. Challenge yourself and try to do some impressive things over the next 12 months. And make sure you study for that GMAT, take a prep course, and get a consultant to help you with your package assembly (or at least a friend who knows something about the process....good luck.
