...and i started in the lower 150s too (shh! don't tell anyone!) and ended up with a dream score many long months later.
vince, thank you for adding to the "it may take longer-term study to achieve a substantial score increase" data. not everyone needs to, of course, and not everyone will be able to meet their goals within a reasonable amount of time, but in my opinion, not enough students consider the possibility of more extended study.
i take a lot of crap around here for being on the slow train to LSAT score junction, both from the quick-study-to-high-score crowd and the prep-test-cancel-prep-retake-disappointment-prep-retake-dammit crowd. my response is:
i think some with firm score and school ranking goals would be best served by being flexible with their study plans, and take the test when they are ready, rather than when it fits best into their schedule and plans like the SATs.

back on topic:
OP, for a non-native speaker like yourself, my usual advice to only focus on real lsat material might be supplemented with some outside reading, but i really don't know. i'd just say, don't sacrifice too much time with real lsat material to do so. you aren't being tested on how well you read the economist, after all. the passages in the lsat are chosen specifically for content and structure, and i just don't know if you'll be replicating that closely enough to be useful. for pure language translation...maybe.
vince what do you mean by "translation drills"? oooh oooh oooh!!! even as a native english speaker, lsac's convoluted use of language in structuring stimuli, especially near the end of the sections, gives me heartburn. of course, it's planned that way, the bastards. any tips for a confused english speaker with a ginormous vocabulary?
maybe she's a halfie?
ugh, don't say that name in my presence. (and i still owe you a PM, vince; i'll give you the background on "halfie" then.)
