It would be to easy to quote your tag, yes.
Honestly, it really depends on your weaknesses. I'm terrible at math, and I barely, barely prepared for that part, and I'm good with english, so I barely prepared for that as well. Basically, I didn't do jack shit in preparation. I got a perfect score on the essay (which isn't calculated into your final score), and I was in the 87th percentile on the English portion. I kinda did terrible in the math portion, which averaged my score to be around 630. It really brought me down BAD. I would recommend focusing on the math area, for sure. More importantly, focus on the areas that you know you aren't too good at.
