My teacher is excellent at what he teaches. Everything he says is very easy to understand, even if his class is a high-difficulty AP course. The lessons he gives are always interesting; he always has something interesting and fun prepared each day. Mr. Clark always praises our achievements and doesn't criticize our failures, even if we have many. My teacher is always willing to help, even when it's not related to the subject he's teaching; his motivational phrases inspire me to do more than I have done so far.
