This is great, and something I looked into when I was pursuing my bachelors, but it's important to note this is something ONLY worth considering after finishing a relevant udacity/mit course, and then making sure the syllabus matches up with that of the local university's teacher's that will be administering the exam.

Also, at my school, which was a mediocre local university, I believe you still needed 70% to pass an examination for accreditation.
