[CPA is a WIP]

Salutations all:

Hope everyone is having an awesome day! My post is comprised of a couple of inquiries. Firstly, I have been grinding with the job search as of late. I was informed the IRS is hiring agents (small business/self-employed division), so would a career in the federal government be a great move? Would you opine that this agency awards annual raises and opporunities for advancement? The duties intrigue me and I am more than qualified for the role. Moreover, I currently work as a senior accountant with my municipality.

Secondly, I cannot afford a full-blown CPA course at the moment, so I found Beckers books dirt cheap online, but no test bank is included. That said if I purchased the books and purchased a test bank from NINJA, Wiley or Gleim, would I be adequately prepared to take the exam?

Thank you for your time.
