Hi erubes1, in terms of GMAT, the higher it is the better. Having said that, if you don't think you can get it above 740+, I don't see the point of retaking it. The number of years in the field is relative. Even though you only have 2 years of WE, if you can demonstrate your maturity and leadership given these two years, you'll be better off than a person who has been working for 5 years with no leadership opportunity. Your 2.6 will be a concern, so you'll most likely have to explain what had happened: laziness, family problems, etc. You want to sound to the adcoms that you're a different person from who you are when you were in college. Also realize that top 20's statistics vary a whole bunch. Harvard has an average GPA of 3.65 (I think) and Cornell's 3.3. Either way, I think you have a shot if you can put in a super strong application and be able to answer why you need this now and what your goals are. In conclusion, there's much more to the application than a 2.6/710. You'll have to distinguish yourself from the person next door and be able to stand out in a positive way. It's impossible to calculate the "odds", but I'd say you have a shot in the top 20.
