This professor does not lecture about what is on the test. The tests are heavily weighted and have multiple questions that have not been reviewed. If you want to read the entire book and teach yourself, take this professor. She has extremely high expectations for her students who are in an intro class.

The tests that she gives us have nothing to do with what we work on in class. Everyone I have asked in this class has been getting consistent D's and F's on the test and it is difficult to get a C. Other MCB 181 classes cover completely different content, she has absolutely unrealistic expectations of her students. I am a 4.0 student hoping for a C

Unreasonably difficult for an intro course. Exams average Ds. Its a "flipped classroom" aka u gotta learn all the material on ur own and go to the mandatory lectures to learn nothing useful. She reads through slides very quickly and briefly and spends 90% of class time on group work and icebreakers. Only surviving since I took ap bio previously.

She hasn't brushed up on her Biology knowledge, so there are often errors in her lectures that she goes on to incorrectly teach. She also gives very vague study guides for the exams and tells you to "review everything" if you want to do well. I studied and did well in the class, but beware - it's a lot of self-teaching and SO much group work.

To succeed in the class, you need to pay attention to any scientific studies/disease pathways she talks about and work really hard on getting the right answers to discussion and then you'll be fine. I didn't read the textbook either and it was okay.

I did not score well on tests because she is not a good teacher, although she is a lovely person, I cannot retain any information from her. I even went to all of the SI sessions and spent hours studying. She gave a lot of extra credit, but it did not help that much.

You can tell she cares about her students but has no idea how to teach. You will spend half of class doing group work or practice problems, and when she actually lectures, she will get way too in-depth that you lose the whole concept. Exam questions are meant to trick you. Just save yourself and find another way to take the class.

1 semester later and I still think about how awful this class was. I ended with a 89.8% and I couldn't do anything about it since the "0.02%" credit throughout the semester should've been enough." I wish she weren't a professor for this subject since no one seems to like her teaching or scores well.

I know this is a flipped class but she seriously does little teaching in class that pertains to the exams. The questions on the exams are weird and conceptual questions which i'm sure everyone gets wrong. Get any other teacher.

Dr. Gray loves her students. She gives some extra credit. For an introductory course, this class is hard. She will give you two options at the beginning of the semester. Either get to use a card for exams or dont. We chose not to, as she claimed the exams would be made easier. Liar. And her practice exams? Useless. Content isnt the same.

When that class average for exams is constantly around 60%, it's not the hundreds of students fault, that is on the professor. Test are very conceptual. Lectures are a waste of time, but you can't miss them because of your attendance grade, which in this class you're going to need all the points you can get. If you hate yourself, take this class.

The class is really bad, and the class average is a 60% for the exams. Her class is also lessons ahead of the other mcb classes. It doesn't even matter how hard you study, you will still get a bad grade on the exams. She also puts questions that were not taught on the exams. Her ratings are true.

Dr. Gray is a nice person, but I believe that this is the worst class I have ever taken. The class average for the first exam (perhaps the easiest exam of the class) was a 69.7%. For the second midterm, as Dr. Gray notes, "Our class average was a 56.3%, with a standard deviation of 22.67%. 60% of the total grade is determined by just 4 midterms.

Out of all the teachers at this school, this was the one that truly crushed my dreams. 60% of the class was based on exam grades. Most people averaged about 55%-65% at this rate you'd be lucky just to pass. I lost my academic scholarship because of her class. So please do not make the same mistake I did, schedule early and take someone else.

Lectures are slides only, goes over info so fast it's impossible to take notes. TAs are useless, barely understand the material themselves. Homework is unnecessary and unhelpful. We are 2 units ahead of other classes. Other classes don't have free response on exams but we do. Exam average is so low E1:63.63%, E2:56.3% (other classes are 75-80%)

Professor Gray cares about her students a lot and is very understanding. However, I do not believe that she is a good professor, nor are her lectures good. She reads through the slides very fast and you are expected to do A LOT of work/ understanding outside of class to succeed. I would not recommend taking MCB 181 with her specifically.

This professor is AWFUL. Please avoid her and her course at all cost. She designs her Exams to trick you. She takes attendance and participation so seriously but during her lectures she does nothing but read off of slides and no new information is given. On her quizzes and practice exams you will never get the right answers unless you search for it

Do not take this prof if you do not have to. This class should have been an easy A however her exams made that pretty challenging. Class exam averages were horrible (70.7, 61,63,63%) adds over 20% of cumulative information to each exam. Class and work for class is easy but not beneficial what so ever.

Most traumatic class ever! Your grade is 60% exams that are both multiple choice and short answer questions. She gives so much material to study and the study guide means nothing. Exam averages were always around 50% and she would not curve, she would instead say we were not trying hard enough. Even TA's found it hard to communicate with her

Corin Gray was a nice teacher, she is very sweet but she does not know how to teach a class. I have been stressed out about this class for the longest. majority of your grade is based on test. The TAs are more helpful then the ACTUAL teacher. She's a very sweet person, but she needs to do better as a teacher.

If you need to take MCB181, I would take any other professor. She does not have very engaging lectures and she doesn't explain the material well at all. She has a ton of guest speakers come in to class instead of teaching the actual content of the course. Everything I learned in this course I either already knew or taught myself.

If you want a professor who doesn't grade on time and prevents students from graduating on schedule, take this class. Many of us couldn't walk at commencement due to delayed grades, and there was no sympathy or urgency shown despite how important this moment was after four years of hard work.

This class was very hard and moved fast. Tests were tricky and the averages were low (one was a 56). SI sessions and TA hours are a must. She gave 3 bonus points total for things like attendance, probably because she saw how much we were struggling. Just try to get a different professor.

Dr. Gray isn't as horrible as people say, but she is not the greatest professor for the average learner. She really is sweet, but I just think she has to change how she does the lecture and the slides. You just need to be willing to commit to studying for this class, and you should do fine. Just don't take a class that's hard at the same time.

Dr. Gray is a very sweet woman, and I feel like she takes criticism very well. She is always looking for ways to improve her class. However, there is a lot of homework, and you WILL need to do a lot of studying outside of this class to succeed. This class isn't for people who expect to get a good grade but not put in any effort.

Genuinely, the most difficult professor I have ever had. TRY NOT TO TAKE AT ALL COSTS. Choose the other professor for this class because this one rather have most of her exams be made up of trick questions to tank your grade instead of the actually concepts learned. She just reads off the slides the entire time but attendance is mandatory. YIKES.

She's genuinely a great professor. She offers many exam-prep resources and extra credit, and I found her lectures and office hours helpful. I recommend going to SI sessions, TA office hours, and especially her office hours. Other than that, this course is really dependent on how much you put into it, so expect to spend ample time studying for it.

The professor was a weird grader because her expectations for free-response questions were never clear. She graded assignments under the homework category that were never stated to be graded, and it was not in the syllabus that this counted as homework. Lectures and textbooks barely help, and I relied on SI sessions and Khan Academy.
