Re: British Citizenship Test
Given that it's likely that most of the answers are factual and easily findable on the Internet, I wouldn't be surprised if it could ace a citizenship test.
I'm equally unsurprised that it aced the bar exam. For all the fancy talk, most law cases hinge on lawyers being able to pore through vast volumes of written law and case law, and find precedents that meet the pattern. If a model has been fed the laws and a bunch of legal texts as part of its training it should do well enough. And doing well in mathematical tasks should be trivial, as long as it just needs to spout out results and not explain its reasoning.
Having said all that, it's still pretty impressive!!!
