Lisa is good but did not perform that well lately. We transferred her to the other class, thereby increasing the average rating of the other class, but also the average rating of your class as well. A very good move for the whole school.</p> <p>Ma’am where’s Denis?</p> <p>We increased the rating of the two classes by moving him to the other class.</p> <p>Ma’am, what’s going on?</p> <p>You know you’re our top performer, Henry. Your singleton class has the highest average rating ever.</p> <p>Can I go to the other class and further improve their rating?</p> <p>Don’t be silly"/></p>
