A solid 60% of your grade is based on the group you pick in the first week, so pick well. Grading policy isn't hard to deal with, however she keeps an eye on attendance and says in the syllabus she'll dock up to 10% of your grade on poor attendance, so attend lectures even though they're horrible.

Nada is a nervous lecturer if I have ever seen one. At times she is solid and lecture will be remotely interesting. Other times, she will flip back and forth between slides too fast, speed up the pace of the class, slow it down. Brace yourself, because as soon as you go on reddit, you might be on the same topic for 20 minutes or get so lost you'll need to go to r/maps to find you way out. Regardless, this is a worthwhile class, and I'm sure Nada will eventually become a better lecturer.

Did I attend class? No.
Did I do well regardless? Yes.

Hope that answers your questions
