Absolutely loved his class! He's a really good teacher and knows the material inside out. I took Genetics with him and thank God I had him and not one of the other professors. Attendance isn't mandatory since he records his lectures, but I recommend attending his lectures cause you can ask questions and he dressed up as a lamb for Halloween lol.

He is a good professor, he is very lecture heavy, but you do not have to attend class because they are posted, yet it is recommended. I took him for BIO 1, but this course was the only option to write a review under. Overall, good class only thing that's frustrating is your grade is completely 10% take-home quizzes, 60% midterms, 30% final.

Professor Grabiner was amazing at lecturing! The class was straightforward and based on assessments. The quizzes were online with multiple attempts, but the exams were in person and not very difficult at all. If you come to class, or watch the lectures on zoom, take notes, and do the study guides he provides you should be able to succeed.

I'd say he's pretty much okay. He does grade by a few things (3 midterms, final, and quizzes). Quizzes were easy but counted for a small percentage of your grade. As for the midterms, I suggest using his study guides he provides and rewatching his recorded lectures. One bad grade on the midterm can take a toll on your grade so beware and do well.

His exams were about 30 questions each and filled with unfair, confusing and difficult questions. Questions were correct because he said so. He would just tell us to study more. He does not even hand back exams and gives very broad feedback via gradescope. Plus exams make up most of our grade. Although he is very dedicated and explains things well.

I thought Dr. G was a great lecturer, they were very engaging. But his exams were extremely difficult, and we were not given the exams back ever. The only study material he gave were broad overall gist questions, but they did not help prepare for the questions on the exam. If exams were fair, the class would be great.

He was a solid professor and definitely has a love for the subject. Overall grade was primarily determined by 3 midterms and a final, but one midterm grade gets dropped.

Dr.G is a great lecturer and does a good job of breaking down complex concepts. This class is not lecture-heavy and is more of a Socratic seminar. Be prepared to work on your public speaking skills because you will have to do (casual) presentations. class conversations and well as peer presentations are great preparation for the exams.

If you take him he is not the worst option. If you don't go to class or office hours you won't understand what's going on unless you have a strong background in Biology. Other professors do exam corrections, he doesn't so it kind of screws you if you are a bad exam taker. He has a lot of office hours so its really what you put into the class.

This was honestly one of the easiest class I have ever taken. There isn't a lot of work besides from attending lecture (which isn't mandatory), taking quizzes (he drops the lowest), and taking unit exams (he replaces your lowest with your final exam grade if your final exam grade is higher). Just attend the lectures, take notes, and you're all set.

With that being said the exams make up 85% of your grade and quizzes are 15%. I felt like it was hard to get an A in the class because of how exams are weighted. Was helpful to rewatch lectures.

He was an excellent teacher. His lectures were always very thorough, so make sure to show up to those.

As long as you are going to his lectures and doing the practice problems he assigns for (optional) homework, you should be completely fine.

GOATED Professor, Really cares about the class and about students. He tries his best to help students to get the best grades. Attendance is not mandatory and lowkey is not really necessary because all you need to know is going to be on slides. All exam questions are based on slides material, you don't need anything else to do well in class.

Professor Grabiner was great at explaining concepts, which made it really easy to understand the content. He was really fair with grading, and the exams never had any curveballs. I was able to do well in the class because he was very clear in teaching the content as well as outlining expectations.

I was very intimidated for this class, but Dr. Grabiner was an amazing professor. He reinvigorated my love for cell biology and explained complex topics in a very digestible way. The lectures are very well structured and everything you need to know is covered. He is available outside of class and always willing to help. BEST Genetics Prof by far!

Awesome professor. his tests can be a little challenging, but overall they are fair. You will be fine as long as you do the practice quizzes, go over the slides, and the practice questions.

Classic lecture style class. Questions are tests are very reasonable, and if you pay attention in class, you should be able to get a good grade. No homework aside from quizzes that you can retake

Prof Grabiner is a good lecturer and gives plenty of outside help if needed. Class is very test-heavy; grades are based on 4 unit exams and a final. There are a few online quizzes, too, but they're not worth much of your grade. It is attainable to do well if you just start studying for exams early and use the practice problems.

grabiner was honestly one of the best professors ive had so far in college he's quite chill and his exams aren't the hardest imo as long as you study the lecture slides and lectures themselves (which he records if you don't want to go to class since attendance isn't mandatory) you're pretty much guaranteed at least an A or A- big enjoyer of him :D

He records lectures but tests are difficult like A B C AorC or All of the above (application based), little room for error since tests are 85% of ur grade. To see mistakes u have to go to office hours where he pulls up the question on his computer (2 questions limit) so u never learn from ur mistakes or even look at the test. Avoid for ur sanity

Your entire grade depends on the exams, but honestly just go to the lectures, take good notes and you'll be fine. He's a great lecturer!

He's a good but not a great professor imo. Great organization and resources on canvas, exams are on paper but you def have to put in a good amount of studying for them. Quizzes are online and he gives a lot of practice problems which really helps. If you put in the work you'll do well in his class.

85% of your grade is exams. He does drop the lowest exam but I would spend hours studying and still just do mediocre. He talks super fast but records lectures so you can go back. He gives a good amount of practice I just wish wasnt so exam heavy. You also don't ever see your full exam! Good prof and nice guy just a rough if your're a bad test taker

I would avoid him if you can. His lectures are very tedious. No matter what, you will have to go back to the lecture slides, and it still won't have everything you need for his exam. I don't recommend going to his office hours; he is very condescending and doesn't help at all. If you don't understand the way he teaches it, you will fail.

I'm gonna be so honest, I just didn't like him. He clearly has no desire to be teaching, is rude and condescending to students who simply ask questions, and majorly overcomplicates simple concepts. His exams were wordy and often focused heavily on concepts only mentioned briefly in lecture. Exams are also very few questions and 85% of your grade.

I didn't really have any interactions with him, but he has a very lecture heavy class. His tests felt more like reading comprehension questions and would be worded strangely. Very exam heavy, make sure to do the quizzes he assigned over and over again to get the hang of how he likes to work questions.

Grabiner was a good professor -- he's very passionate about what he teaches and he knows a lot about it. Attendance is not mandatory he records every lecture. However, his tests are difficult and for those who don't know how to study the material will struggle -- it's mostly memorization. If you're willing to put the work in, you will do well.

Brilliant lecturer. MC tests can be a little wordy and tricky at times, but college-level readers should be prepped for them. Practice quizzes and lecture slides provides everything you need for the exams. All lectures are recorded. Useful review lectures prior to every exam.

Dr. G was an incredible professor; he presented information in a way that made sense and gave plenty of practice material that reflected the questions well. Questions could be a bit conveluded some times but if you put time into practice they shouldnt trip you up. He was very passionate about the subject and I reccomend attending each lecture.

He does a great job of making difficult concepts a more digestible. Lectures are recorded and not mandatory but going helps a lot. You can tell that he wants you to do well, but you have to put in the effort. Exams are entirely multiple choice, which I found to be tough. But, he replaces your lowest midterm score with your final grade which helps

Dr. G's class has been one of my favorites! Classes are lecture heavy, but they are really engaging and he structures them in a way that is easy to understand and pick up (they are also recorded, which is helpful). He gives you so many resources to do well in his exams (do the practice problems he makes!). Definitely recommend taking him.
