Hi Ntwkengg,
Both Sch A's had to do with personal history. The first one I provided apparently wasn't detailed enough so of course CIC requested another one that required much more detail.
I perceived that the issue had to do with distance education. CIC wanted to ascertain whether the studies were done in my home country or in the country that offered the exam. (I guess that would have had some implications for police record as well so they were just making sure)
Everything seems to be ok so far, so I am just keeping my fingers crossed.
