Lecture, or singing class? Hmm..

As usual, we had another of student's learning and development class this morning. Our lecturer came in and said, hey! let's have an open book test! Whoa.. It's like all of a sudden, without warning. Well, at least it's open book test. I had another quiz which most of us totally don't know about last week. Our lecturer didn't inform us about it directly, but she posted in myguru. Guess it's our fault we didn't log into it so often. These two tests really came as a surprise. It's like they are saying:"Surprise~~~". Gosh.. That's one thing. Another thing is, We had this open book test for an hour, and the other hour he asked our classmates to sing in front of the class. What's the point man?? Wasting time. Come to think of it, even if he didn't do that, he would also waste time by talking nonsense in class. No difference.
