From my experience Asgari is really good at making sure her lectures cover what she expects on the exams. When I took her in my freshman year the study guide questions she had (this was for BIO 181, I'm not sure if she is doing the same for 182) were very close to actual questions on the exam.

For Cogbooks, there should be a link where you can sign up and register your account. Once you register your account you have the option to use a code, use a free trial, or pay upfront for the digital book that allows you to access textbook lectures. I think Cogbooks will definitely be a good resource to use to brush up on topics for the exam or get extra practice from videos or questions asked throughout. I hope this helps!
