It seems easier to me than Lifespan 1, but I got a B.
I had a lot of multiple answer questions, where you check all the boxes. I had more nutrition related questions than I expected. There were some critical thinking questions, too. If I were to take it, again, I would go over the metabolic diseases and read over the Rx and nutritional needs & common nutrient imbalances in those. So, it would help use the practice tests & study guide to show you what areas to study. I used Study Guide 101 and a Vango notes audio book (audible.com) for a medical surgical nursing book.
