One Experience of China Undergraduate Mathematical Contest in Modeling(part2) (continue with part 1) It was a common situation that we didn’t agree with each other and we would keep discussing or inquiring teachers until we got the same idea. We also found the suitable part of ourselves. I was mainly in charge of turning the practical problems into a math question and doing interesting images conveying our ideas. The boy from math department was our leader, and he was skilled at programing. The girl from computing department was detailed and patient and she was responsible for composition. During the UMCM, everyone was diligent and all of us had a sleep of less than ten hours of the whole three days. At last, our efforts payed off we achieved the second prizes of China. The experience of attending the UMCM is very wonderful and never be forgotten by me. What I learned is not only learning skills but also team spirits.
