Math Tutoring

I had another class with Alex today. He asked me to have the class yesterday because he had a math test today. But then, he said he suddenly changed his mind yesterday after school, that we had class today. He said he did pretty ok on his test...... We'll see. :P
He said he started the new chapter, statistics, in class. He said he learned the concepts of median, mean and mode. He seemed to be doing ok with them. We went over the questions and he struggled with some questions, but I explained them to him.
