Hello all,
First time poster, avid reader of Gmatclub (at least, since December...
Background:I'm currently working on slamming my weakest areas based on my diagnostic - sentence correction (where I got 1/13 right). Btw I'm a native speaker and I'm using
MGMAT - aka the best in the biz.
I'd love some study tips on SC. Please bear in mind that I"m aiming for a 760, so I'm not trying to screw around here...but also trying to be efficient

Hoping to take the test 2-3 months from now.
Current statusSo far I've read the
MGMAT SC book 2-3 times --
except for the advanced sections (ch. 11-13), which I haven't touched. I've glanced through 11 and it did now blow my mind away, although I still wonder if I should sit down and internalize what's in there...
Now I'm working on the OG questions and have been doing decent. My stats so far look like: 22/25 correct with avg time of 2:03. My problem set has leaned towards the easy/medium so far. So far the questions I've missed have been because I didn't fully read the answer choices (i.e. long wordy sentences) which I attribute to stupid mistakes. Obviously I have to work through the harder problems to really get a better assessment...
Key questions on SC study strategyQuestion #1 -- Should I (a) work through all of OG 13/2nd edition books and
then read/internalize the advanced chapters of
MGMAT SC (so that I can apply those rules when I start taking CAT's)? Or, should I (b) review the advanced chapters of
MGMAT SC book,
then finish working the OG questions, esp. the hardere questions that I have not yet worked through?
Question #2 -- Since SC excellence boils down to continuous practice after you've gotten down the rules, then what should I practice with between when I finish the OG problems (in a week's time) and when I start CAT's (in 1-1.5 months from now)? In this time, I"m going to work through the math sections and GMATClub math tests, but would love to throw in 5-10 SC questions each day.
Is there another source with well-regarded SC questions?!?! or should I simply go through all the OG SC questions a second time?
Would love to hear your thoughts. Promise to speak well of whoever can provide a great answer
