Yep, except for microeconomic reform though, I said that was unlikely.
In all honesty, these questions are fairly generic and a student that did practice essays wouldn't have any issues. I actually like q28 more than a CAD specific question because you can link BOP + exchange rates + macro policies together, this suits students that have a strong understanding of current issues and can draw out implications (it's easier for top students to distinguish themselves from the rest). The hardest part is staying logical in your writing and not going off on a tangent.
