Hi
srishj24,
I had a similar experience. Consistently scoring well (700-720) in the mocks (e-gmat,
experts global, gmatclub and what not), but received a similar score (660 and 590 on first attempt) on the D-Day.
On retrospection and with some guidance from mentors on this forum, I was able to identify one of the many reasons. This later helped to plan the approach and to focus on the target area.
The study material that we usually use is built around past questions from GMAT or the mocks available from GMAT. The underlying approach to hard level questions in such material is hence same or sometimes with some minor tweaks. Same is applicable for the mocks offered by prep companies. This, therefore, leads to inflated scores on the mocks. The underlying concept of approaching a question remains same. However, GMAT spends thousands of dollars on each question and thus has a very challenging question bank.
I believe that you can improve your verbal score a lot. Try solving questions that are posted by Bunuel and other moderators on the forum on daily basis. I have observed that a lot of them are different and new. Solving questions from LSAT source will also help you a lot. And please keep in mind to maintain accuracy level of more than 90% for easy questions, 80% for medium questions and 70% for hard questions.
All said, there are just some bad days. In one of my attempts, I got only 6 questions wrong on the quant section and scored Q42 (before this attempt, I was always scoring >Q49). On my evaluation of the ESR, I found the questions asked on that exam were "650 level" throughout the exam (Even after getting 10 questions correct in a row). I don't know, may be GMAT ran out of hard questions on that day. So, faltering on medium level questions affected my score drastically.
GMAT is definitely a test of your ability but more importantly it is also a test of your patience. You have worked hard. You have the capability (as you mock score shows). Don't let some bad days bring down your confidence. You will definitely get there. All the best.
