Critical reasoning stands out as your weakest area--was this also true of your mocks? I would focus on that area, drilling many questions from the GMATClub question banks. Always try to figure out the author's specific claim--most errors come from being sloppy with that formulation. The good news is you have a great quant score and that you reached a 720 during practice. As long as that was a true score (i.e., not a retake of a CAT), getting a 720 or higher shouldn't be that difficult.
Another tip--if you take the verbal section first, you can use the 2-minute tutorial and other introductory screens to write down "12345" or "abcde" 35 times on your scratch paper. Then you can cross out incorrect answers as you go (I also underline "maybes") and don't have to spend time doing this in the exam. If you take a lot of notes on the text, you can space these out so you still have room to write.
