I should get used to working on verbal section under stress. I feel that the first two points you have made might be valuable to me.
Thanks.
First find where exactly you were beaten in verbal or what are most weak areas and then remove time pressure of next attempt. Just work on those areas with consistency, right material and right approach. I am sure that in addition to SC your CR and RC must also be weak and needs a great attention so dissect the areas to work and then work on each individually. For Instance:
In SC:
-Modifiers concepts
-Parallelism concepts
In CR:
-Bold face role played BFRP questions (Also known as methods of reasoning questions)
-Weakening
-Strengthening
-Which of ....best logically completes argument... type question
-Similar reasoning questions or parallel reasoning questions
In RC:
-Of course same MP (Main point questions)
-Passage infers
-Passage suggests
-Most likely to agree
-Most likely to be true
-Which of following is the question which can be answered by the passage as a whole?
Changing locations where you study, or time when you take the test could make a difference but I think you are in best position to judge yourself whether it was a failure of circumstances (such as time, location etc) or failure of concepts or both.
