To all the hardworking and dedicated students and teachers of Khan Academy:

this is my very first post here, and as the first it will be one of the most special.

I have witnessed so many helpful teachers and students that will explain things to me in the most kind and understanding way they can. My last 6 weeks here has been wonderful because of them.

Nowadays there are so little people that can help and I am deeply appreciative of the people here who help me.

Once again, thank you dearly. Chen Xi, student
