How should I study for the FG exam?  What topics are covered most?  Is it a low of raw memorization?  How did you study?  How many total hours should I plan to put in?

There is a very valuable class you can take to go over the topics covered in your classical training called Reg Review. It's not offered in all states, but you can go to the website and find out.  They have a (thick) review book, so that plus your textbooks/course notes should get you prepared.  The class is basically a review in case you have questions on the material after you're done preparing, it's not a how-to.  You need to basically already know how to do it.  The book has problems and solutions, so it's a good resource for brushing up.  Good way to prepare.

Here's the link for the August courses.  They hold the course at hotels, in case you're making a trip and want to stay.
