Disclaimer: This post would mainly help if you are struggling on Verbal. Also, this worked for me; please adapt what is most suitable for you.
Here's my experience:
My goal was to reach 80% verbal.
Difference in my two attempts:
I had completed OG10, 11, Scoretop, Kaplan, Manhattan, Sets (about 25 - great to overcome timing issues + some real GMAT type questions - it's a must!)
In SC and CR, I could easily remove 3 choices. The problem was to select from the last two remaining choices. My RC was ok.
I had read Manhattan SC, but still could not relate to GMAT style (of when is present continuous or past perfect is correct / incorrect). I used to go by what sounds good.
I took 1-to-1 tutoring at ScoreLeap. I must say, ScoreLeap is an expert in GMAT question types and pattern. I had decided to take GMAT in next 10 days since I wanted to submit my new scores after the deadline. No choice, but to get up 4:30 am, drive 20 KMs and attend class at 5:00 am. Rush to office by 8:30am phew! (Remembered my 12th class timings). Didn't have much time but to follow his rules.
SC: ScoreLeap made SC very simple with few basic rules like when is -ing, having + ed, were, had been etc. are correct / incorrect. Just follow blindly and apply it! This led to easy elimination of many choices within seconds. I was now more looking for the rules, instead of, spending time in what sounds good.
CR: Nothing new, ScoreLeap gave a trick to paraphrase CR in a new style and to write down the conclusion before looking at answers. This worked amazingly especially for assumption and weakness type questions.
RC: His RC approach (FIRE) is nice; Again the key in RC is to paraphrase and identify the trigger points.
Followed the rules for each question type and I could see improvement in practice tests.
Quant: I hardly touched for 15 hours in this attempt. Just revised GMAT prep 175 questions in VIP section and solved all practice questions. I was more focusing on verbal to cross the 80% barrier.
