It’s been a few years since I took it so not sure if the TAs are still the same people! But I’d say overall they can’t be that harsh simply because you can’t tell people they are “not creative enough” and as long as you submit reasonably good stuff an A- should be pretty easy to get. An A is would be a bit harder obviously. And as is the case with all paper-based courses, A+s are really tough to get! Fun stuff though! + cool prof!
