Hello there my friend!
I like the title of your post, digital boy!
Niiice.
Well let's get started - first of all your profile is both good and interesting - you come from a country with very few MBA applications, and you seem to have done very well - Top 50 out of 250000!!!! I don't know how many can say that!
Obviously if you can get a higher GMAT it will help as top 10 can be very competitive even with a great profile. And whether you get that target score of not might cause you to desire to adjust your list (essentially I think you can apply to Top 10 schools even with your current score, but you will have to play it safer by adding top 20 schools).
We would love to learn more about you and the rest of your profile (including all the nice extras like volunteer work and ECs), so why don't you drop us a line?
We work often in neighboring Indonesia, and our head consultant Yaron Dahan has a good feel for applications from your region, so drop us a line and we will hook you up with him for a Free Consultation:
