well, that's an awfully general question - certainly too general to be answered in any way that could remotely be described as complete.
still, here are a couple of suggestions:
suggestions:
* collect a lot of data. take many practice tests, solve official guide problems, etc., and then make a tally of the # of errors of each type that you failed to see (and the # of times you detected 'errors' that weren't actually errors).
* the next time you do a group of problems (whether on a practice test or just random problems), keep ONE OR TWO of the most persistent errors in mind. scan the sentences with an eagle eye for those ONE OR TWO errors, looking only perfunctorily for the other errors. if you do this, you will almost certainly detect those ONE OR TWO errors every time you see them.
* do the same for other error types on later sets of problems, once again ONE OR TWO error types at a time.
* eventually you'll start nailing them all more consistently.

if you've ever played a sport, been a dancer, etc., you know that you can only concentrate intently on one or two physical skills at a time. that truth is unchanged for mental skills such as those required by the gmat.

by the way: you could always use this information to make flash cards: put an entire problem (including answer choices), unmarked, on the front of a flash card, and then list the issues - in the original and in the answer choices - on the back of the card. this will take you a great deal of time, so you shouldn't do it for every problem; if there are stubborn problems that you've missed more than once, though, make cards for each of them.
