As far as blogs go, I have a large pool to draw from. I am addicted to Google Reader. I follow 165 blogs. It's an illness, really.
One blog that may be of interest to CPA candidates is the CPA Exam Preparation Blog by Roger CPA Review. While I can't attest to their CPA review products, I do know that the blog often has well written articles with good tips, tricks, and reminders. This company is forward-thinking. They have live, online, and usb review courses. I also happen to know that they were working on an iPhone application.
I am interested in hearing what CPA exam review products have worked well for you, so please comment about your experiences.
