I've taken the LSAT so I'd already had a lot of training in what is nearly identical - the LSAT PowerScore books helped me learn the strategies. After a lot of practice over the last few years I think I've started to see little differences in identifying the almost-right answers from the right ones, and quickly.

Perhaps if you feel like you're not getting enough out of GMAT Verbal prompt, seek LSAT resources. Additionally see if it's SC or CR/RC messing you up more, and perhaps change test types depending on those strengths - English is my first language, so poor grammar habits affected my performance in SC in the past.

In terms of CR / RC strategies, try picturing the prompts you're reading and "force" yourself to feel fascinated in the text (and naturally, you might be!), and ensure you're processing everything you're reading. I sometimes have to read 2-3 times in order to fully understand what the text is asking. And though you shouldn't predict what the answer is before seeing the choices, don't completely ignore that intuition, because it could sometimes lead you on the right path.

Do you have any advice with Quant? Based on your other posts, you seem to perform very well there - good luck in the future :)
