I've applied for the TFN now, because I didn't know it was needed until today :(
Can I still confirm my Uni application and fill out my timetable, then confirm my TFN number later (before the census date)???
This is where I got my information from. I can't believe photocells apparently involve the cathode ray tube. Both answers are correct imo. And if a reliable source like Jacaranda is wrong, the HSC markers should accept both answers
