Are you aspiring for a 700 in the GMAT and trying to figure out why your score is stuck at 650 and not hitting the 700 mark?
Here are potential reasons.
Firstly, are you ready for higher order reasoning and problem solving? Find out, how consistently you have performed in data sufficiency questions, inference questions in reading comprehension and weaken/strengthen questions in critical reasoning( assuming you worked out Official guide questions)
Secondly, while taking the computer based tests, did you fall short of time and guessed more than 5 question in either/both QA and VA section. If so penalty and poor pacing and time management is the issue.
Thirdly, your concentration wears of while you are working on the last part of the Verbal Ability section. Build stamina, slowly and steadily by taking many 4hrs tests.
To raise your score from 650 to 700, let’s say a re-taker do spend 30 days reworking on concepts, practicing with hundreds of tougher questions and analyse these questions to improve your performance.
