Course itself was fine but Heidi is a lazy bum who doesn't know how to teach properly. Just uploaded online lecs with in person mc tests and uses kritik so she basically has to do 0 work.

The content was interesting, but the delivery was awful. Typical engelhardt-just recorded lectures on Learn and they aren't even new.

Heidi definitely redeemed herself in this course (coming from someone who she emailed to dropout in first year BIOL 130). I think it's because this course goes over content she did her PhD on or maybe because this course is mostly grade 12 biology with more details. I felt it was the same level of difficulty as Biol 273 instead of having the pearson modules you have the kritiks and quizzes to boost your grade. Instead of iclicker she had 2 learn quizzes per class for participation which force you to come to class because they're password protected. I thought Heidi explained the content well and explicitly stated what would be heavily tested on midterms and exams and had her usual question…

Heidi lowkey cooked on this one

Took this course with Dr. Engelhert in Winter 2022 where half of the course was online and the other half in person. The marking scheme was 30% kritik (5% x 6), 2 midterms 35% (15% and 20%), 5% participation quizzes and 25% final exam. This course is not hard. The textbook is not required as the exam questions are from the recorded screencasts and slides. The hardest part may be the Kritiks since often times peers will actually give you a lower mark so you may need to dispute your mark to have it marked higher. Finished with a low 90 but 80+ is definitely possible.
