ESR Analysis Request

I cancelled my past attempt . I scheduled my next take on 27th . I could not get ESR till yesterday .Since I have few days left , I want to make sure that I work on relevant weaknesses . I actually could not understand any of the passages completely on the test day because of nervousness .
My analysis :
1. My SC and RC ability represent my true ability , My CR ability does not represent my true ability .
2. I spent a bit more time in the first quarter than needed . Thus has to be reduced .
3. I have to improve my RC ability . (Got 2 RC's in 3rd quarter and you can see the result ).
4. My average time for correct answers for SC is 1:30 minutes , for CR is 2:30 minutes , and for RC is 2:00 minutes . So , I require 72 minutes to complete the exam . Now , should I guess ? If so , should I guess instantly when I encounter one of the questions from my weak areas mentioned below ? Precisely , how should I get that extra 7 minutes .
5.Nervousness damaged my first quarter . I have difficulty comprehending when I am nervous.
6..My weak areas
a. In CR , questions including Percentages , Proportions
b. In RC, questions including Inference .egmat
