That’s true. You should focus more on information from NDP as I did the same. Board member gets the impression that you prepared well for the hearing. They won’t give a shit about your case if you don’t give a shit about your case.You should still be on the safer side and use articles from NDP. During my hearing the board member literally read out stuff from NDP articles related to my situation. I wouldn't personally use other articles since IRB won't access those while making a decision, but they will look at NDP ones. Its just a better look than some random ass article.
