Mallory scored higher on an IQ test than Alex, and again on a rematch. The episode nevr clarified if thw test was incorrect or what. The entire series shows that Alex was significantly more intelligent than Mallory, so what's up with this episode?

Interesring point, but if she was actually smart, she would have figured out to apply herself, or that she didn't have to play dumb. Also, in episodes where only the family is involved, she acts dumb around them. And in the IQ test episode, she kept correcting Alex's speech when in fact he was right and she was wrong. 'Smartitude.'
