First you have to look up your state's requirements for things such as credit hour requirements, course requirements, CPA exams, and working requirements. Then, the CPA Central website by NASBA keeps track of your application and CPA exams, where you can keep up with the status of your exams and licensing. Also, when you become affiliated with a firm, or if you buy your own program, (I used Becker), they can help you build a schedule to track your CPA exam progress.
Hope this helps!

Here is what I will suggest:
For each course or CPA subject matter that you complete, use the completion of it to test yourself on your knowledge of the subject matter by answering/completing the past CPA exams. You can buy a compilation book of the past exams. It is an investment that is very much worth the money (for the cost of the book), time and effort (more time to focus on what your weak points are when you take a prep/review course).
When testing yourself, make sure you time yourself so you get into the habit of taking the test under time pressure. Sometimes, being able to answer all 50 questions (even if 1/3 of them are "smart" guesses), will give you a higher probability of scoring a pass grade.
Again, I am assuming that your question is not really literal in the sense that you can easily track if you have taken enough credit to take the CPA exam.
Hope that helps.
