PARIS: Louise, what did you get?
LOUISE: Highlights, just around my face.
PARIS: You will take them again and do better.
Although Paris is correct that you can retake the PSAT, you can only do it once every twelve months. So Louise would need to wait until October 2002 to retake it – by which time, she would have taken the actual SAT, making it redundant. If you want to take your PSATs more than once, you need to start at least a year in advance. I feel as if Paris would know this.
Note that Louise’s results are apparently lower than Madeline’s, and it is actually she who is worse academically than her best friend. Louise seemed to be the brighter one in Season 1, but Paris berates her by saying, “You don’t study, you don’t apply yourself”, as if she knows Louise is capable of doing better, but is simply lazy.
