I only used Darius’s course and passed REG! I have used many other resources for the other subjects, and I wish I had known about Darius, would have saved me so much time. I studied the shortest amount of time for REG compared to other subjects because Darius will teach you exactly what you need to know to pass the exam. I love how he goes through questions right after he teaches you a concept because it really sticks with you. His lectures are easy to focus on because he doesn’t sound like he is reading from a script. I highly recommend Darius for anyone studying for the CPA exams.
