This reminds me of what I learned about myself during my years spent at the university. I observed that in the morning my brain is better at understanding new concepts. Mornings were the best time for me to practice and improve problem solving, but I tend to remember less details of what I come across. However, at about 2pm my brain appears to switch to memorizing mode, where I struggle with problem solving compared to the morning, but I will remember a lot more of what I read. I structured my learning activity leveraging this observation. Even to this day (am 46) I can feel the same tendency, e.g., if a problem seems somewhat difficult, I just wait until the next morning, if I can, only to find it easy to come up with some solution that seemed out of reach the previous evening. Also, I try to do most of my reading at night (well, life with a family doesn't leave a whole lot of options for timing anyway).
