personal preference but personally i wouldn't advise it, also most lectures have lecture slides you take notes on, rather than take note from scracth-again though, each to their own
In sem 1, I ended up taking notes on the slides for chem and biol and that worked out nicely except I got tired of having to print all the lectures (I did it double sided to save paper which takes effort to do). I had an exercise book for the tutes which was okay.
I then tried writing my own notes in semester 2, but stopped doing that halfway through the semester as I always missed content with the fast lecturers and had to rewrite crap. For the tutes, I wrote on the LHS pages of my notes book, but that ended up messy.
I ended up with the same marks +/- 1% so you could probably do whatever you prefer.
Going to try a new system this semester that combines the best of both options.
