Hi Hvat,
Assuming that you took these Practice Tests in a realistic fashion that matches-up with how you will take the Official EA, then we should assume that the results are an accurate indicator of your current 'ability level.' Since you are so close to your Official Test Date at this point, you should NOT try to do too much additional studying. In these last couple of days, you should limit your studies to general practice and light review (NO more Practice Tests and NO 'cramming') - you would be better served by getting some extra rest so that you can go into Test Day calm, clear-headed and ready to work.
After you've taken the EA, if you have any questions or would like to discuss your results, then you can feel free to PM or email me directly.
GMAT assassins aren't born, they're made,
