One possible version:

Wang Hai was my classmate in junior school. For a time we both wanted to be on the top ten list. But it was hard; he did better in math than me while I was better at English.

At first, we each saw the other as a competitor and competed with each other and we never exchanged learning experience, and even didn’t talk to each other. As time went on, we both found we didn’t make any progress. The teacher knew that and had a talk with us. She told us to cooperate by helping each other at the weak point. We did so, and several months later, our “weak subjects” improved a lot and at last we realized our dreams.

This experience made me realize the importance of cooperation even in a competitive situation.
