We might want to consider what "average" actually means. Most people on this forum would score higher than that, some substantially higher. Most people on this forum write better than Jodi does, because they aren't trying to use words or grammar constructions that are over their heads. So, lets not overestimate Jodi. Let's not overestimate her especially because those IQ tests (I don't know this for sure) are probably multiple choice. This does note reflect active knowledge. Jodi's knowledge is very passive. She can mimic word and grammar usage, but she rarely gets it quite right when she goes for high falutin'; however, this kind of usage is generally good enough to make choices on a multiple choice exam. Where Jodi excels is in manipulation. This takes a certain kind of brain: I mentioned yesterday that folks on the autism spectrum—even very high achievers—can't manipulate people with communication. She make get IQ points for this ability, I don't know.
Other than manipulation, Jodi would not be assessed very highly in terms of raw brains, IMO. She gives herself away when she messes up, e.g., Green-witch, or not realizing how much blood a wound to a given body part would produce (head wounds are very bloody, in my experience, and those were probably the least bloody strikes she made at Travis).
New flash for Jodi: a person of "college material" generally exceeds IQ 110.
Another news flash for Jodi: IQ is scored on a "bell curve". In other words, there is not an equal number of individuals at each score. "Normal" is 70% of the population. 15% are above "normal", 15% below. But there is also a margin for error, and retakes of the test will result in different scores. Most of the 15% above "normal" will be just over 115, if the test uses 115 for the norm (some use 119). The 15% above normal are also spread out to >145: the demographic as the numbers spread out get fewer and fewer.

Juan Martinez is light years ahead of Jodi in brains. He would score much higher on an IQ test. If we had his numbers for comparison, Jodi would look, very, very ordinary, I feel sure. Note how elevated JM's vocabulary is on the fly. And note how he communicates tactically and strategically, and he rarely uses a filler such as ummm, and all the information he has at his command. Plus, he's bilingual, I believe. These skills are extraordinary: they require raw talent, hard work, and hanging out with other folks who are very brainy. My guess is, he'd be up in the <.8% category.
Also, I believe JM and Demarte were strategically selective in how they referred to Jodi's scores. Demarte highlighted verbal abiiities, on purpose, IMO, because they could—in the minds of a juror—enhance the image of Jodi as someone who manipulates language, lies easily, mis-communicates purposefully, etc. Trap for Jodi. Note: we didn't hear about Jodi's math, logic, or reasoning skills (not to mention artistic skills). And the DT wouldn't dream of impugning Demarte's accuracy on the verbal scores: Jodi imagines she's genius in this regard. BOOM!
