Some friends approached and asked me this question lately, and to be honest I don't have the exact answer :D. I got the scholarship for my postgraduate degree now by grace, and of course miracle (don't ask how miraculous it is :p). I know that if God wants me to pursue this degree, He will open the way, and He did it. Not by might, not by my power, not that I'm so smart (but I'm smart though, hehe), but by the Spirit of God. He is so faithful and gracious. But apart from this fact, there are some points that I want to share, and these are true for me. Hope it will be useful for those of you who seek for answer.
