@tvatsu: you are warmly welcome to discuss! Where are you? so we can match the time schedule to discuss.
@prat: oh yes, the timing problem, but it would not a big deal if we can arrange the time schedule to match with anyone.
Because of the time difference, I would suggest that we separate 400 problems from 4 tests by 8. So we will have 50 problems to discuss each time, and if we start from this Sunday, we will finish it on next Sunday, then one last w. for review and free discussion. What do you guys think?
The AIM or YM conference, it would be good!
