Are you absolutely certain it was better when you were younger? I don't remember much from high school or college, especially for the classes where I crammed the night before exams. If you do remember your studies better from youth, consider that a high school or college course is typically several months' worth of daily classes, while a Coursera class is maybe 10 hours total where your brain thinks you're vegging out at home alone watching TV. If you could somehow spare a full-time semester today at 41, I bet you'd retain a good amount of what you learned.
