Thank you very much everyone!
Few of my experiences to help others correct their faults:
My first question in Q was a PS. I took 3 min (unbelievable, I still didn't get an ans that matched the choices.) I moved on. I had 2 sequences and 2 probabilities and some traps in abs. But, I did not analyse my level while taking the test. Those of you who think that these type of q's come only when you are scoring well, can you guess my Q score?
I took six GMATprep tests after reinstalling. I had repeated q's, some from
OG. For your analysis, I never had more than one prob. or seq. in each test. I scored 49 in one and 50 in all the rest. (I felt bad that I never got a 51! I know, my std. was not that high in all the sections. I did not do math after high school.)
Yesterday, I was surprised to see a 44! If you guess it was because I got my first q wrong, may or may not. Once I got a second q wrong in GMATprep and still got a 50. In the real test, we have some experimental q's.
I know that I was weak in V. I spent more time to figure out and correct my faults. Still, I never reached a 40 in GMATPrep. However, I scored (not in order) 680, 690, 690, 700, 720, 720 because of high Q score. I noticed that my number of incorrect ans were almost the same, though they were either more on SC or more on RC and not consistently on one section. But, I got many new q's in V except for one or two. I knew, my GMATprep scores were not a good indicator. Still, I decided to put a period to my preparations.
Hope this would help some in their analysis. It is just a test, not life. Keep going. Wish you all the best!
