Update:
In April I had the chance to meet Elder Bednar. He spoke at my BYU graduation and I just happened to be in the right place to meet him before we had the processional. He was very nice and asked about me, my major, and plans. We also discussed his son, whom I had met previously. It was a great experience and the highlight of my graduation day. His eyes were pure and he is a true servant of God.

Additionally, I took a class at BYU on the lives of the Apostles. I relied on some documents from that class.
