SAT critical reading = improvement issues?

It's nice that you're improving your vocabulary. But anyways, aside from doing that, you should probably do lots of reading. Like before bed or something. By doing so, you'll again.. become familiar with more vocabulary and get accustomed to reading and grasping the ideas of what it states. When you're taking the test, don't spend lots of time reading the pages. You should just skim over the pages quickly and you'll probably get the general idea. Just take lots of practice tests as well.
