Several years ago I was getting my MBA and in the middle of my stats class. During a particular challenging chapter I found myself way behind for a homework assignment that day. Someone mentioned, "Hey you should go talk to Dave about it". What a great idea. So I walked well really ran down to his office. Although he seemed in the middle of something as I explained my sitution about needing help his eyes seemed to light up with this chance to teach. He spent the next hour thoroughly reviewing my assignment. Upon completion he let me know that should be "good enough for a B". A week later I showed Dave my graded assignment with an A on the top. He told me the teacher must be and easier grader.
