If you have nice penmanship then yes, writing will sufice, especially if they mail you the form for you to fill out (as oppossed to an electronic document). I did both. I filled my Nova secondary out by hand and when I went in for the interviewer the dean and the other gentlemen exclaimed that they were looking forward to meeting me as they said they couldn't stop looking at my handwriting (in a good way) 🙂 .
