My wife worked for a local public accounting firm for almost 5 years after school while trying to pass those exams. They wouldn't even let her out of work on Saturdays during tax season to study for a Monday test. She was getting 73s on BEC three tests in a row even with Becker; it was brutal and costly. She finally got fed up and found a job in the private sector working under a CFO nearing retirement. She managed to pass all four tests easily within a year

There's a reason the really big firms pay you $80K+ straight out of school to sit at a desk for six months and study and pass those tests.
