People learn best in different ways. Some learn best by reading, some by tinkering, some by watching and listening. I heard this over and over in school and college.

I don’t think it has anything to do with reading speed. When taking in complex technical information, you spend more time thinking and trying to understand than actually reading.

If you’re finding that you can quickly race through content, it probably just means you find the content easy to understand because you’re already familiar with many concepts.
