Darius’s I-75 course is top notch! His videos really break down the material in a clear and concise manner for ANYONE to understand. His approach gives you the base knowledge, whereas other review programs give you very high level. I recommend his course who anyone who needs the topics to be thoroughly explained. I was using another review course and really was not liking it. I found Darius and have been able to pass 3 out of 4 of the exams and plan on passing the next within no time. Thanks for your help Darius!
