Worst class i've ever taken. It seems as though she has no clue what she's doing!! she just mumbles and writes down things on the projector that make no sense. Quizzes and tests do not line up with what she teaches. Thank god for SI sessions and tutors, or else i would've failed this class. WOULD NOT RECOMMEND!!

Once she got in the hang of teaching she was amazing and her teaching has helped me to understand everything very well. She is helpful and her notes are very detailed making the class easier. She also makes jokes while teaching and it lightens up the class' mood. "Fertilization, Something none of you have practiced" Highly recommend her!

I'm taking her online biology class and she grades very harshly, so it's practically impossible to get a high A in anything. Her quizzes aren't fair either, because they don't let you go back to look over your answers to make sure you answered everything correctly. I'm having the worst experience in her class. I wish she would help more.

Make yourself known in Professor T's office hours. By no means is this class easy, but it is not impossible if you take the time to get the work done, go to tutoring, and study a lot. Professor T is not fair by any means, much of what is tested on is more in depth than what the lecture covers and the quizzes are not uniform which is frustrating.

Heidi Trathnigg is nice but she is the worst professor I've had so far. She gives a ton of unnecessary homework. She does NOT teach a ton of topics in class. It is expected of you to watch a ton of long videos on your own time. She will then quiz and test us on only the videos and most the time what she actually teaches in class is not on the test

She is a very passionate person, but her lecture style is not good. Her lectures did not align with the labs and I was often left confused and she expects everyone to watch lecture videos outside of class instead of teaching in class. We also had weekly quizzes instead of biweekly quizzes, an exam on reading week, and lots of busy work.

Stay away. Her method of the flipped classroom setting is not good. Youre expected to watch lecture videos for homework, along with a lengthy reading/questions assignment, then a post lecture assignment, and group work. Not to mention her in class lectures are a direct COPY of the lecture videos, but attendance is mandatory for points.

Professor Trathnigg is completely unapproachable and unhelpful. She is lecture heavy and fails to explain the material if you were to have questions. If we did group work during the lecture, she would publicly call out people that had questions by stating, "Who can tell them the answer to the question we just went over?". Don't take this class.

Professor T was very solid in BIO182. I really enjoyed her style of lecture and having practice questions during lecture allowed for active recall. Bi-weekly quizzes really were not that hard as most of the questions were covered in the same lecture. Exams are fairly easy as long as you study based off of lecture notes and SI Practice exams.

She was an interesting prof, treated students like middle schoolers and “called out” talking students during class. If you weren't paying attention you would be called on and made fun of by her when you said you didn't know. Her lectures were ok but she was weird everytime.

Okay, a lot of people rate her bad, but honestly she is a really good professor and knows her stuff. If you dedicate yourself to her class and take notes and study, you can get an A. ALSO PLEASE GO TO SI. Genuiely my first test I got a 63% (class average was 47%) and I went to SI and got an 80% next test. You actually need to try and learn to get A

She is not helpful to students during her class. Whenever you ask for help, she will just say go look at her lecture videos or other worksheets and not give out help herself. Her exams are very different from her worksheets and practice exams. She always opens things last minute making it hard to study/work. And she relies heavy on her TA's.

Lots of homework

Pretty clear cut class... take notes, do assignments, test. She's not very open to answering questions which is quite unhelpful, usually she'll call on other students to answer. Make sure you pay extra attention to her video lectures as they seem unimportant, but that info is what will make or break your test score.

You can turn everything up to a week late and at the end of the semester you can drop and retake 1 of the 4 quizzes taken during the class. the content is hard but she's very forgiving. about 3 hours of reading every week and 5 assignments that come with that reading.
