If you already are familiar with the subject, as many people are who take exams, then you obviously will not need to spend that many hours preparing for the exam. How many hours per week you study is your decision based on how fast or how slowly you wish to cover the required material. Our experience indicates that if you enroll with about 45 credits, you can finish your associate degree in less than a year. If you enroll with about 90 credits, you can finish your bachelor's degree in 1-2 years. However, this is only an average.
Some people take less time, some more.
It depends on you and how much time you have available to commit to your education each week. If you use testing as a way to earn credits, you will generally shorten the time to earn your degree. How you earn your remaining credits will determine your final cost. Your advisor will plan your program with you keeping in mind your learning style, and your life and financial situation. If you have not completed your degree by the end of your first year's enrollment, you will need to pay the Annual Advisement and Records Maintenance fee to remain enrolled.
