I also study form lecture notes and what I would rmend is to convert ppt to PDF and upload it to OneNote. This will help you to make note-taking during the lecture much easier. When you go home read ppt slides and your notes in OneNote and then watch related Lecturio videos. Make notes from those video lectures andbine your lecture notes and lecturio notes with each other. This is how I study in medical school and it works pretty well.
