Hi OP
I used the DIT program (I'm not sure about "customized study schedule sessions" - I just went along with the 15-day schedule they have laid out) and I thought it wasn't that special, but it was really nice to have when I was finally finished with 2nd year and needed to get studying for the real thing. I had no idea where to start and DIT kind of gave me that structure I really needed. I think I didn't even finish it (got to the 13th day out of 15) and just started doing things on my own. It helped me to get through basically all of First Aid, which was great, because it focused my attention to the things I needed to review. DIT videos are NOT anything like Kaplan. Kaplan is its own course intended to try to teach you the materials. DIT assumes you know it already, but gives you a guide to help you get through the most important stuff. So, from my perspective, use it as a way to give you some guidance and structure in your studying 🙂
