Change Profile Attribute 'graduation' to 'yearInSchool'

OK, so a quick discussion. I'm more than happy to produce brackets for one line conditionals, although my preference is without. However, there are numerous instances of my doing so historically throughout this code, not just what appears in the PR, and I'm not sure it's worthwhile to go back and change them all. I somewhat liken it to not eliminating non used imports, in that it's not overly critical. What are your thoughts?
