Let me add to the praise for this year's ACF Nationals questions.
They were probably the best set of difficult ACF-style questions I've
heard in my 4 years.
I especially appreciated the economics questions, which were of
utmost quality. Even the biography question on Hicks seemed to reward
actual economics knowlege. The questions on Black-Scholes and duopoly
models were much appreciated, but I fear that those two topics are
too obscure to take up entire questions. I suspect that only an econ
major could have a shot at any points with those questions.
I would also like to publicly praise V. Vaz for demonstrating the
valor of driving 100 in a 55 zone in crowded traffic.
