Ever since my first year at uni, my reading has been transformed. The lectures forced me to read highly mathematical and algorithmic books, some of which took multiple hours per page if you want to comprehend everything. Now, my reading has slowed down drastically (10-100 times slower) but when I'm done with reading something, I understand it well enough to explain all the key concepts to someone else. Another thing is that I somehow memorize where things are, that is, when I remember some passage, I know where to look in the book almost down to the page (this doesn't work for PDFs which is one of the reasons why I avoid them). But I've lost the ability to read for pleasure, I used to be able to finish a novel in an evening.
