Agree that you should use your remaining resources hiring a tutor. At this stage of the game, you should know the areas that challenge you -- and when you get your tutor make sure that you are crystal clear that you are having issues with x,y and z and need to master them. The more focused you are about your problems, the higher the yield your investment will produce. If you instruct the tutor that your problem is with the overall test, they may take a broad approach and waster a lot of your time and money.
This is how specific you should be:
I am having problems answering reading comprehension questions that focus on scientific passages.
I have problems answering two step geometry problems on the data sufficiency section.
In problem solving, I have problems answering questions that incorporate both geometry and algebra.
