Sleeping in class

Today we have a biology test in the morning. It's a very hard test so that i slept late last night. After the test, I ate lunch with my classmates. It was almost the class time when we finished it. Unfortunately, there was still a English test in the class that I ran out of my energy in the test. I felt so tired, but i still tried my best to keep awake. At last , I finally falled sleep and was found by the teacher. Oh, my god! It's not my day today!
