On the one hand: yes. And it's a good way of getting the notes to review later.
On the other hand: the act of writing it down, even if you never look at it again, helps you remember the information.

On the third hand(?!): if you have to hurry to write it all down you might end up with a terrible, disfigured mess of notes that you can't make head or tail of when you go study later on.
