Ben Smith was my instructor I think prep expert is definitely the most knowledgeable course you can take to prepare you for the ACT and I believe you get you money's worth in materials and instruction but saying that it is a huge undertaking in terms of workload and i found it very difficult to keep up with even though a schedule was provided. Throughout the class a lot of time is spent on review and i wish it was more lesson oriented and your wrong answers were explained to you on your graded sheet. My instructor was very enthusiastic and tried to make class fun but overall i found it hard to focus at home. I also wish you could keep all your materials forever considering how much you pay.
