give yourself about 3 months - although that was back in the day when you had to talk all 4 parts at once. Now you can study one part for like 3 weeks, take it, study for 3 weeks, take part 2, study, etc.
Also, if you get the degree, and you get the work experience (i.e. 2 years of public accounting or working under a CPA) you are a fool for not getting the cert.
Even if you do nothing with, it literally adds tens of thousands of dollars per year to your value. I went into IT consulting after stints at Pricewaterhouse and Grant Thornton, and the most critical areas in any IT shop are financial reporting, so the fact that I'm a CPA that's knows IT controls / SOx stuff, and application development stuff makes me a gold mine. ignore anyone that tells you not to get it, even if you don't plan to be an auditor.
