I wouldn't rely too heavily on everything just "coming back." Getting a 6 on a section is more in line with good guessing than having the knowledge required to succeed. Since you insist on taking it at the end of this month, PASSAGES, PASSAGES, PASSAGES. Once you complete these passages, post-game the heck out of them (look at why the question was wrong, and figure out how to correct). If you find it is mostly background info you need, I would push the date back. You need to be realistic about this. People study for 3 months and still only score 27's. It won't be easy taking a month and gaining five points on the sciences. Best of luck to you, though. I hope it does work out! Let us know how it goes!
