Have you thought about creating flashcards? This is a good technique to constantly review and nail down the principles.

some of my students are, ironically, frustrated by excessive ambition: they try to look for too many kinds of mistakes at once, thus failing to notice just about anything because their attention is spread too thinly.

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.

according to your suggestions, here is my game plan. I will go through all OG questions and mark off where I get wrong and why. From this point, I will take little lesson from the sc manhattan book and powerscore sc book. Then redo these mistakes with the aim of fixing them. For later purposes, I will keep in mind where I usually went wrong! Good with you?

that sounds like a decent plan.

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.
