Growing up I tended to go through spurts of being able to learn and not being able to absorb new information. I often had a delay and was often behind other kids for awhile with new material. But then seemingly out of nowhere it'd 'click' and I'd surge ahead. This would typically repeat with each new thing.
I had my own slow pace learning for pretty much anything. Some things didn't click in in until substantially later. Things like counting money (change) beyond the simplest ways and understanding/reading a face clock h:m:s, didn't click at all until my sophomore year. I have an unidentified math learning disability though, and I'm not sure how much that played a part.
I overall seemed to even out in my ability to learn in highschool so it hasn't been too much of a problem since those younger years. Though I do tend to still have my own pace.
