For CR and RC, you do need some resources that specifically teach you how to answer those kinds of questions. Here are some free resources, but you may also want to look into some books.

I do also think it's a great idea to do some GMAT-like reading every day. Here are some good sources:

We don't have any in-person classes in Indianapolis, but we do offer online classes that you can join from anywhere. I have people from all over the world joining my online classes.
You can see a description and schedules here:
http://www.manhattangmat.com/Programs/Complete-CourseWe let people sit in on the first class for free, so you can check it out and decide whether you think it's for you. (The only caveat: if that class sells out, then you won't be able to sign up for it; if you like it, you'll have to join a different class section.)
Most companies do offer free intro classes, so check out whatever companies you may have heard of and decide which program you think would be the best fit for you. (I'm biased and of course think our program is the best :) but you're the consumer, so go do your research and decide!)
So that's your next step: do some research and figure out whether you want to join a class. If so, you'll follow that syllabus. If not, you'll need to identify some CR and RC resources and start to put together your own study plan. Let me know what you decide.
