How to raise SAT score in a month? HELP

<p>I've taken the SAT twice and my scores have been pretty average. The first time i took it was the June after my junior year. I didn't study at all and received a 1760.
Math:580
Critical Reading:620
Writing:560, 8 essay
The second time I took the test was October and I received a 1780.. I studied for about an hour looking up tips on youtube. What surprised me was that my writing and CR went down.
Math: 650
CR: 580
Writing: 550, 8 essay
I'm thinking about taking the December Sat and putting in more effort studying this time. I honestly believe im capable of a 2000 and was wondering how i should go about studying considering the shortage of time. Any tips and advice is appreciated.</p>
