I passed the paper exam but I didn't file the form or paid the $30 fees. 5 years later, I had to take the computer exam which is much easier. But the time people take exam 3, they don't remember much form exam 1. On paper, you sat for 2 days taking 4 exams for thee hours each which made you more knowledgeable and you had to remember more stuff for longer periods of time. At that time the IRS used to say that an EA would know more about taxes than a CPA but now that statement might not be correct.
Even though they have made the exam so easy now (you can take 1 exam every 4 months), I have seen tax preparers doing taxes for 5 years or more, not able to pass the exams. That's like being a cook for 5 years and not being able to cook a steak. Some of the arguments about the EA exam above are like a cook stating "I am an Italian cook and why will I learn how to make quesadillas or how to cook hamburgers since they are not in my menu".
I wished the IRS had a masters on taxes and a phd. So the EA would the bachelors degree and harder exams for people wanting to know more.
By the way, in August, I attended the HR block beginners class, unfortunately my instructor didn't know much but their book is EXCELLENT.
