7x15 - Full House

It's the day before D.J.'s SAT, and she's so nervous about it that when she goes to sleep that night, she has a nightmare about it in which everything possible goes wrong: D.J. oversleeps on the day of the test and is late, and Ms. Twitchel, a neighbor D.J. yelled at, is the teacher, Danny and Becky come by to broadcast the test live, and with too many last-minute changes to the test, D.J. fails the test with not even her name written correctly. When D.J. wakes up from this nightmare, Danny convinces her that she doesn't have to be so nervous about the SAT, and her teacher turns out to be a much friendlier teacher named Mrs. Moffatt.
