Hi. The last week is not really the time to gain significant improvement.
The last week is usually for you to gain confidence, composure and to repeat the results in performance you’ve been able to show on the practice tests.
What I mean is that if you still need to improve, you’re not one week away from your test.
Usually you want to achieve time management by taking timed quizzes. Solve small batches of questions restrict timing enforced and start with easier questions and move up to a mix of easy and medium and then once you start heating 90% accuracy introducing questions into your mix.
It’s good that you know the concept of questions so now you need to speed up, but this may mean applying different strategies on verbal so that you can move faster through the questions.
