One of the worst professors I've taken so far; She goes extremely fast during lectures which makes it hard to keep up and makes you answer questions during class that counts for your participation grade (via Course Key)

Prof. is very caring and wants all of her students to succeed. It was a tough course for me because science is not my thing but she gives a lot of other assignments and extra credit that can help you make up for low test scores. 3 midterms, one optional final, plenty of easy assignments, and one really easy paper. Take her!

For a 101 class she was the most difficult professor I have ever had. She talks extremely fast during lectures & goes in such detail that it's almost impossible to keep up. She uses a an app that you have to pay for as a source of attendance & mini quizzes which you take during lecture. Luckily she took a leave of absence & was replaced by Chaffee!

Really great professor, she explained every topic very well and used great examples to tie it into our daily lives. It is easy to get a good grade if you keep up with the online quizzes, and study for the exams. A downside of this course is that she makes you buy an app in order to check in to attendance.

Professor Hahn talks really fast during her lectures but she does provide access to the power point slides so that helps a lot. You have to buy an app called "coursekey" in order for her to keep track of attendance and to answer questions for class points. Just show up and take notes and you should be just fine.

The study guides are vague, but if you pay attention and really try to understand the subject it's not as hard as people make it seem. You do have to pay for the website that takes attendance and gives you homework (both separate). Go to class, pay attention, and focus on the homework. It is hard but it that is biology.

Prof Hahn was good. The class was pretty difficult. A LOT of reading and notes, but she gives you a guide. The worst part of the class was the group work which was very often. If you get a bad group you are stuck with them the entire year. Everything is due by Friday at 9 pm. Keep up on it, it is too much at the end of the week. Textbook is free.

3/4 assignments due every Friday. IMO, she's not understanding. The only good things I'd say about her class is that it's well structured and she responds quickly (usually within 24hrs). Other than that, the amount of reading & studying she expects is unreal. Wayyyy too much for a 101 class. She only extends deadlines for tech issues, nothing else.

Took Bio 101 to learn about genetic diseases, doesn't count towards my major. Completely regret my decision because it took up my entire life just to barely be passing. Each week we have hours of information overload, ridiculously difficult exams and knowledge checks. When the class average is a 61% on an exam, something needs to be adjusted.

I wish I listened to the previous ratings and didn't take Professor Hahn. I thought this class was going to be simple and interesting and it was not simple. There are 3 midterm/final exams, weekly knowledge checks, a semester group project, and four module case studies. This class felt more like a major class than a GE class.

PLEASE AVOID AT ALL COSTS! I'm doing you a favor I wasn't able to drop the class so I got stuck with it. She is a tough grader who gives an excessive amount of workload. Her exams are 3 parts with little time and she would give exams during the break or holidays. Unless you are a biology major don't take this class for general ED it was excessive.

Asynchronous class with sm work. Hours worth of notes per week with weekly Knowledge Checks, sem long group project, 4 case studies, and 4 tests. Really difficult for a GE class and wouldn't recommend. Also was really difficult to get ahold of and didn't give good feedback.

The only way I survived this class was because my group was so fun. Krista is probably nice outside of class, but expect to deal with group projects every month, long video lectures that she refuses to give in person, and group work being done in class with little instruction. If you HAVE to take this class, my advice is good luck.

There are lots of weekly notes, about 6-7 pages. Group assignments the entire semester. The exams are three parts with very limited time too. For a 100 course, she expects a lot. Does not accept late work. It's very time-consuming. Don't take her, I don't recommend it!!!

I was initially scared because of the reviews, but Prof. Hahn was fine. She had online lectures and in-class group assignments. The whole class was based on group work, which can make or break your grade depending on your group. The coursework is very independent. She only had one paper, and the final was to make a bio-themed board game.

Very heavy workload for a 100 level class. 4 tests including the final each having three parts, case studies that require group work, one paper that gets combined into an encyclopedia project with your group. Make sure to have good communication with your group as they are assigned at the beginning of the semester. Overall wouldn't recommend.

This was a flipped class, and it wasn't the first flipped class I've taken, but it was the worst. It was too much work for a 101 class, a daily assignment due at 8 pm. She rarely graded, so you wouldn't know how you were doing in the class or if you were getting a good grade on the assessments she would assign twice a week.

The worst science class I have ever taken. The professor barely has her own lectures and everything is based on short videos and readings in order to learn material. She is a very harsh grader with confusing directions and is unfair because she is not clear about what she wants. Way too much homework and assignments for a 101 and super difficult.

She HAS NOT input any grades BY HERSELF. BTW if you do bad on the syllabus quiz in the beginning, you are done for the rest of the year because that basically determines your grade she doesn't seem like she has time to put grades in even though it is an online class where she only needs to work from home or wherever. Not that hard to put in some #s

asynchronous class -- She assigns A LOT of work and has group projects every other week, despite the class being online. You have the same group for the whole semester, so if they do not complete their part, you are out of luck. I would look into taking another class or choosing another professor if possible.

To start off, if you ever see this professor on your list of biology classes, I suggest you to not even think about taking her class. She is a harsh grader and will dox points off for the most unnecessary things. On top of that, she assigns a lot of work and is strict with cheating. She will do anything to find out if you are cheating. DON'T TAKE ^

I 100% recommend to absolutely NOT take this class with this professor. For an online asynchronous 101 class, this was one of my hardest classes due to the workload, pointless assignments and incredibly harsh grading. There are multiple assignments a week, quizzes and group assignments every other week. This professor should not be your last option

hardest online class ever. for a fully online class she makes you do group projects and expects them to be done perfectly. everything is at your own pace and you get multiple attempts on hw but quizzes are absurdly hard. you have multiple papers due during the semester, and she takes forever to grade assignments. would not take her at all.

I am not the biggest fan of a flipped classroom, so paying attention to the online lectures was difficult. There was an insane amount of group work and sucked when some didn't show up to distribute the load. Professor Hahn is friendly and helpful, but is very slow when it comes to grading.

This professor literally dox'd points off because one of my group mates couldn't access the google doc for a GROUP ASSIGNMENT like it literally a group assignment.. Aren't we supposed to help each other in a GROUP ASSIGNMENT. I wouldn't recommend taking her if you want an easy class cause she provides so much work it feels like i'm a biology major.

You will never know your grade in this class because she takes forever to do it. Her assessments are impossible unless you spend hours reading prerecorded lectures that only biology majors would understand. The class setup was also confusing in the beginning, as well, missing one integrity quiz took a big 5% chunk off my grade the rest of the year.

This professor uses a flipped classroom method which was confusing at first. You have watch these prerecorded lessons that could take up to 30 to 50 mins and you have to answer questions along with it. There is no final exam. You have to do each assignment with your assigned group.
