Pro's for handwritten notes:
-Info tends to sink in more
-You practice your writing, which is helpful for exams
- It keeps you away from a computer, and with that, the tempations of evils such as MSN!
-You tend to be more careful with what you're writing, because you can't just delete what you've written...also a helpful technique for exams.
Pros for typed notes:
-Neater, and thus-more appealing when you have to actually go back and read them.
-You can type for long periods of time-longer than writing by hand.
-Easy to go back and fix things up...whereas if you've handwritten a huge slab of notes then find something you don't like or that you've left out, you may not bother going back to change it.
-You can print off new copies with the flick of a button, which is good if a page of note gets lost, something spilled on it, or you start daydreaming and scribble stuff all over the page, etc etc...also, if you're a kind person, this also lets you pass them on to friends much quicker and easier.
-MUCH faster.
So yeah...pro's and cons for each. Maybe type them out when you're busy and don't have any exams coming up, and write them out if there are exams around the corner...
