Mending the 400 gap in 2 months?

<p>I'm currently at mid 1900 and planning to score 2300 in Dec test. My writing and math are at around 700 and I think I can boost them up a little more with ease. It is the CR section that pulls everything down. I can only get 38 questions right at most, and the mistakes are in Reading Comprehension. I tried some tips on CC but they only help me do slightly better. Now should I keep doing practice tests or do workbooks instead? And what CR book is suitable for my level and my goal? I only did the blue book, Barron's CR workbook and Barron 2400.
Do you think increasing by 400 in 2 months is feasible given the schoolyear curriculum? Has anyone been in the same situation as me and managed to reach the goal? It would be great if you guys can share me how you do it
Thanks in advance.</p>

<p>anyone please?</p>
