I was very pleased with this product. I was able to complete my PDUs in one (albeit very intense) month. There was a lot of reinforcement of concepts, and I learned quite a bit and did reinforce some concepts I knew already. I was high risk for Covid, so I would have had to have let my certification go inactive until I was vaccinated if it hadn't been for this product. I will likely use it again. I did the video one. Incredibly convenient.
