Hello,
astiles67. I am not sure what the source of these mock tests may be, but I would advise
against taking a fourth right away, since you cannot expect anything different by doing what you have always done, and you may be wasting valuable resources on such a trial-and-error process. Take the time to review more in between mocks. And why does your Verbal score have to be a 45+? That is quite high. I know Verbal instructors with scores in that range. You are not applying to a Verbal-heavy program, are you?
I understand mental fatigue. It is something that everyone has to contend with on such a lengthy exam. You may want to try physical exercise, mindfulness, and/or meditation to get your head in the right space. But the best way to improve your timing across the exam is to develop a stronger understanding of the questions themselves. Evidently, you are taking too long to process the questions and answer choices, and it is costing you later on. This is where practice
outside of mock exams can really help. I prefer sets of ten questions at a time, believe it or not. Sometimes I do twenty, but rarely will I go up to thirty. The goal is to build a strong base through each set of practice questions, and also to gain information on how long I tend to take on each type of question. For instance, I may spend 3-4 minutes on a tough CR or RC question, but I do not sweat it, since I know through my broader practice sets that my timing tends to hover around 2 minutes per question. That is,
even if I spend 3-4 minutes on, say, one CR question, my practice has taught me that across five or ten such questions, the timing will come down to a reasonable level. And it is this sort of mental edge that can help me move smoothly through an entire exam.
In short, I would stress accuracy first, timing later. When you increase your understanding of the material, your timing will come down on its own as a result. And when you take your next mock thereafter, you will notice a difference.
I hope that helps. Good luck with your studies.
