When reading new materials online on a wiki page or something, I feel those words just slip through and I don’t really understand so I keep returning to what I have read. It’s quite annoying maybe I need to take notes at same time but since it’s online material so I can’t mark as I read a PDF in the reader. Maybe should find a extension or sth to help me take notes. Or maybe I should be more patient while reading and keep in mind that I can go on only making sure I understand what I’ve read.
