i received a message regarding this thread.

we hear this sort of thing a lot -- the "i always choose wrong when i'm down to two choices" thing -- and, well, it's probably not true.

what's probably happening is this:
* your review concentrates, primarily or exclusively, on problems that you got WRONG.
* so, the problems on which you guessed correctly between two choices get marginalized (or, if you're only going over the wrong answers, get ignored altogether).
* therefore, it starts to appear as though you always blow the choices between 2 options.
as an extreme (and obvious) illustration, if you are only reviewing the problems that you got wrong, then it's going to look as though you choose the wrong answer between two options 100% of the time.

try this: do some problems, and actually write down, at the time, whenever you guess between two options. if you do this, you'll almost certainly find that about 50% (or more) of those guesses are right.
