Rarely when people have a vision for improving a process, do they actually do it. Thankfully for you and me, Darius did. Other CPA courses are rushed and their lectures are not done by people who actually prepared the material. Great teachers, like Darius, prepare lessons themselves and truly evaluate how to best break down a concept and how to best organize the information. The course Darius has put together is methodical and thorough. I would highly recommend the i-75 course to anyone trying to pass the CPA exam.
