If you're looking for a good real estate school to prepare you for the Florida broker's exam, you can't do better than the Climer School of Real Estate.
I say this as someone who has been one of their students three times--for broker's pre-licensing, broker's exam prep, and broker's post-licensing. Not only does Ron Climer prepare you for the state exam by teaching you the basics, he will help you to become so comfortable doing investment analysis, closing statements, and real estate math that you'll approach the exam with the confidence you need.
To get a feel for Ron Climer's teaching style, you may want to watch some of his math videos on You Tube. And don't be put off by his Hawaiian shirts and casual manner--This man knows his stuff! He's a truly gifted teacher.
Good luck on the test.
