The family tries to help Bobby get over his test-taking anxieties.
As the family plays a game of lotería (the Mexican version of bingo), Carlota and Bobby arrive home with their BAT (big academic test) test scores. While Carlota got a high score, Bobby ends up failing miserably. Bobby explains that he studied really hard, but as he took the test, he forgot everything he learned. When Carlos states that this is simply a case of test-taking anxiety, he proceeds to help him out.
Carlos' method of helping out Bobby is by having him go through several procedures, like various exercises, cutting down on what he eats, and having him sleep in freezer cold conditions. The next day, Bobby heads off to take the test again. Sometime later, the family has a whole party set up, anticipating Bobby's success. However, when Bobby comes back, he reveals that he failed the test again. This time, Rosa decides to help him out.
Rosa's methods of helping out Bobby out involves food, such as having to rub eggs on him to get rid of negative feelings (much to Ronnie Anne's disgust), banging pots and pans together to drive off evil spirits, having him drink a cup of herbs and spices, and filling his backpack with countless lucky charms. Some time later, Bobby arrives back, and to his disappointment, he failed the test again. This time, Carlota decides to help out.
Carlota's method of helping out Bobby is by having him dress for the occasion. After a haircut from Margarita, putting on a suit and finding the right pose, Bobby heads off, but when he returns, he failed the test again, because he failed to arrive to the test room in time. Realizing that his hopes of getting a good BAT test score is hopeless, Bobby officially calls it quits.
As Bobby works in the mercado, Ronnie Anne, trying to convince Bobby to not give up, discovers to her surprise that Bobby has supreme math skills when it comes to pricing and coupons. This causes Ronnie Anne to realize that Bobby has complete concentration only when he's in the mercado. As a result she comes up with a way to help Bobby out. As Bobby takes the test, he takes it in a mock-up of the mercado, much to the annoyance of the other students, as he constantly talks to himself. As the family watches from outside the school, they are happy that Bobby can finally pass his test without problems.
