Here are my suggestions:
1) First of all, decide your overall target score, and then accordingly decide your sectional target scores. You need to do this to decide how much improvement you need to make, and then to accordingly put in effort and frame your strategies.
2) Identify your all sorts of your conceptual, physical or mental issues. I listed 13 issues with myself after my first GMAT attempt. Working towards those issues improved my score later. You do the same.
3) No need to try any new material for problem solving. Simply spend quality time on filling conceptual gaps by going back to concept modules and by thoroughly analyzing the solutions of questions you've attempted so far. This is the best way to maximize learning. Given the number of questions that you've tried so far, it's enough to cover most concepts that are required.
4) Best way to up your score is to improve in Verbal section. Target SC section as it's easier to improve SC score in short time than is in the other two sections. This is true in general, but you can decide better for yourself.
5) Read my response at

6) Don't try to revise all the questions attempted so far. Pick topics and questions to revise that are either your weakness or frequently tested in GMAT.
7) Evenly split final 14 days before GMAT for learning, testing and revising. Revision is more important than new learning at this stage.
8) For the last 6 days, simply go back to your concept modules and
Error Log.
9) Do not take any mock test 3 days before the exam.
10) Don't overwork yourself. Take sometime out to chill everyday so that your mind can absorb all the learning.
11) Enjoy the process of learning and improving.
You can make significant improvements in your GMAT preparation provided you improve your conceptual understanding of the topics, devise your improvement plan and learn to execute your time management strategies that work for you.
