Passing an engineering exam can't be a matter of being able to afford the right calculator at the right time. Sorry for the thread drift, but I passed my (equally difficult) engineering exams in a time when an HP-67 would have been really nice to have without being able to afford one. Passing these exams required showing that one had understood the principle, not actually solving the problem with numbers. And in real engineering life those systems do not have 7 equations but 700.
