Congratulations on finishing! Pat yourself on the shoulder. You're way ahead of lots of people already. We're proud of you,
I think taking the test each time is a huge investment, requires a lot out of you and your family. GMAT is only the first step of a long marathon. You need to consider what you're willing to invest in the application, the actual program and then later on your career as well. Don't run out of steam at the beginning!
