He's an amazing guy! If he doesn't know an answer to something, he will find it out! If you need to coem by and talk to him, he's always available, always quick return on e-mails, and he genuinely cares about his students. It's his first year, I hope the students don't make him bitter! Oh, yeah....and he's a hottie

He's really the nicest guy ever. His lectures can be unclear... he gets flustered while talking. Backtracks and contradicts himself alot. I wouldn't take him if you really want to learn a lot about Genetics, take him if you could use an easier class. But again, nicest guy ever and grades REALLY easy.

Dr. Bloss is such a nice guy. He's friendly and very approachable. However, his tests are TOO HARD. You study for hours days before, and you'll probably get a D or C on them, at best. There's no way to appropriately prepare for them and his questions are based more on book problems then anything remotely conceptual.

Best professor you could ask for. He's a genius and knows how to explain things in a very learnable manner. He gives really easy tests and quizzes, too.

Dr. Bloss is a literal angel that is always trying his best. His class is by no means an "Easy A" in my opinion, but if you put forth a little bit of effort and do the suggested homework problems , an A is definitely attainable. He really does make lectures enjoyable the best he can & he actually cares about your mental health. An absolute gem.

All his exams are short answer with very few multiple choice. There was always more short answers and it wasn't like the lecture. You really had to comprehend his lectures or you for sure weren't going to do good in his exams. Pre lecture quizzes are super easy.

Dr. Bloss is the most caring professor I've had in college. He works very hard to make sure you understand the concepts. You have to work hard to get a good grade since exams make up a majority of it, but they are designed to test what you learned in lecture and he also gives partial credit. I would definitely take BIO 240 again if I had Bloss.

Dr. Bloss cares about each of his students! He is able to break down genetics into simple terms, but his lectures were long and hard to focus on online. Tests were very fair, but I don't thin I retained much this semester. If you need help go to office hours, he is so sweet and wants everyone to succeed.

Dr. Bloss is very nice! He is sincere and understanding, and puts a lot into his lectures. The option of an online zoom for the lectures is an option as well as in person but all exams are taken in person with a scantron. The exams are a little on the difficult side so this is a class you need to study for, but I would take it again!

Professor Bloss doesn't normally teach Bio 140, and I had him for his first semester but he was never unorganized and will do everything he can to help you get ready for tests and even gives curves 3 tests and a final, but he will put your final grade in for the lowest test to help your grade. Take him over any other professor 10/10

Dr. Bloss was absolutely amazing. He genuinely cared about his students and wanted them to learn however they learned best. When I had to miss class unexpectedly, he talked me through what I missed during office hours. Attendance was optional, and he also had a zoom link for classes. Lots of opportunities for out of class help. Curved all tests.

Dr. Bloss is one of my favorite humans. He is extremely caring and flexible with class. Our class was in-person, but Dr. Bloss also posted recordings of the lectures and that was super helpful for people that need to re-listen like myself. The tests were somewhat challenging as there were MC, T/F, Select All That Apply, and Short Answer. Just study

The class is definitely easier workload wise, and he is a very nice person, but I feel like by giving out slide packets with notes already annotated and never grading any of the homework's, he encourages students to take the easy way out of actually studying, coming to class, and getting the most out of his material.

Most of your grade relies on exams, which have a lot of short answer questions. If you pay attention in class, study the lecture slides, and do the practice exam, you will do well on exams.
