GMAT Strategy

Hi ,

Now that I have finished OG 12 verbal part, I know what kinds of questions are costing me most. Summary of my mistakes are,

CR:

1- I take more time to solve bold-faced questions. I gave correct answer to only 50 % of them.
2- I faced difficulty in answering Assumption and paradox questions in last 90-100 range.
3- The difficult questions in weaken,must be true, assumption and logical complete were answered wrong ( though not all of them)
4- In starting I had a good timing but for the last questions my timings went down ( 2mins/Qs). ( I guess concentration worsen )
5- I am good at strengthen questions.

In OG 12 types of questions doesn't have a good spread I guess.

RC:

1- Inference is an occasional issue. For one paragraph, out of 3 , I answer one wrong on an average. I , otherwise, am now feeling comfortable. I am trying to reduce the time now.
2- RC part seems to be going good, with an average of 1 question wrong per passage. and most of them in below 2 mins.
3- Mistakes in Supporting Idea questions are there. ( which should not have been the case).
4- Application questions has glitches.
5- Structure and Main idea questions seems to be strong with just 1-2 problems.

SC:
Although accuracy has been high, timing is not good. I have issues with Idioms and modifiers. Among (130-140), most of the questions have been answered 50 % are answered wrong, but for the rest errors have been occasional.


Please review my analysis and suggest me how can I improve upon my mistakes .
