I couldn’t believe how heavily featured learning curves were, one of the areas that I was least confident with so it was really deflating. Having said that, by the time I got to the section c question, I only had 5 minutes left so just rushed the variances and wrote a sentence on part (c). I just hope the Pets4All question covered any shortcomings, I wrote a lot on this but didn’t cover everything in detail so hopefully it’s not just marked as waffle. Fingers crossed
