anyhow,I find out that you, daj, are our boss, so I have to try express my gratitude. As you see, the 气氛 here is really not good, which make your work more important! Please give us more materials and more selfconfidence and more hope. Please do your best... I am so fraid that I can learn well Gmat which is thought to be more difficult than GRE. We need a lot of things including physical and spiritual things.
