B)They read each other's tests. The school principal picks B, and he's got just one solution. From now on the twins will have to attend separate classes. Tia and Tamera say: Read our minds and read our lips... No way! But Tamera's got an awesome plan to make the best of a bad situation. She hates math. Tia hates P.E.
