I will suggest of doing 1000 SC as well. Respected mates say it is not worth....but believe me it is. I improved a lot. Hope you will also.
When I started studying back in December I knew my areas on the GMAT from weakest to strongest would be SC-Quant-RC-CR.
With CR/RC only requiring a week or so of refresh as I wrote the LSAT a few years ago and the concepts stuck.
I knew the math would comeback eventually as I was once upon a time, in university, quite handy with numbers.
SC was the turd in the punch-bowl. So I decided to study it first. I read through the MGMAT SC
guide twice and did the OG questions, and had a bit of a handle on it. Since then I've done nothing but quant. Now that I'm doing some full-scale prep tests my SC weakness has resurfaced. I got 4/13 correct in the verbal I completed yesterday - with the first NINE wrong in a row. For me, D-Day is in May. When I'm three weeks out of so I will take two full weeks to review MGMAT SC
again and do every OG question again reviewing, in detail, every answer for every question. I figure thats the only way to make it stick. So take note: work on weaknesses last!
Any other suggestions/tips for weak SC. I'm a native speaker who has taken for granted the innate rules that govern our speech.
