My thoughts on this exam:

After the jarring experience of working through a very difficult Standard 2 exam, I was glad to see the Advanced exam was closer to what I would expect in terms of difficulty. It felt like there was a good mix of easy, medium, and difficult questions. The test overall may have been a tad on the difficult side, with an appreciable number of questions that really tested some deeper understanding.

I liked some of the more challenging questions for the band 6 students, such as question 10 and 31, but some of the harder questions were kind of annoying to work through, such as 29 and 30 (who likes having to lug around extra pronumerals?).

Overall not a bad test, but with the year everyone’s had with less class time and some even having to teach themselves out of their textbooks, maybe students felt otherwise. I’d love to hear any comments you might have on this one! Feel free to drop a comment below or to contact me via email.
