I purchased Darius I-75 course with the hope of ending my struggle with trying to pass REG and now I am speechless; scored 88 the highest of my scores! As an international student, I found it hard to grasp the US tax concepts and Darius really broke the concepts down for me; even business law. I have no doubt that his course would have saved me the failures on previous attempts, had I known about it sooner. The videos are so easy to follow that now I can have a meaningful conversation in US taxation in the real world. I was recommended by a friend to Darius and now I highly recommend Darius to you.
