Yick feels that Mr. Raditch gives him poor marks without even reading his work. Arthur suggests copying some of Stephanie's old assignments and submitting it as Yick's, too see if his marks improve. All is fine for the first little while, until Mr. Raditch discovers that Yick has been cheating. Melanie and Kathleen want to experiment with drugs and buy pills off of Joey, not knowing that they are actually vitamins. After overhearing what Joey has done, they both confront him and demand their money back.
