I recommend Dewall. He was GREAT for his first semester teaching. You can tell he spends a lot of time in preparation, typing up all of his notes for the students to print and making his power points available. He really just wants everyone to learn and do well and he doesn't try to screw you over. He's a really good guy.

I love Brother DeWall. He is a great teacher and very caring. If you read the assignments before class and do your weekly journals you'll do great in this class. There is a mid-term and a final. With the mid-tern I would suggest going into the lab beforehand to practice and to study.

Test questions are tricky. He makes everything harder than it has to be. His AGA assignments are supposed to be test prep. He won't answer questions on them and then doesn't grade them in time for the test so you know if you are doing things right. Very lazy about grading. Hard material, teacher doesn't make it easier!

Tests were a lot trickier than they had to be. Most of it COULD have been scantron but everything was write on so we didn't see our grades until grades were due at the end of the semester (frustrating). AGA assignments were preps for exam but he wouldn't tell you if you got a question right. TAKE the extra credit assignment, it will save you.

DeWall is okay. I don't dislike him, but he is very frustrating. You don't need a textbook. He made the exams more difficult than they had to be and is extremely slow on grading ANYTHING because he only depends on his graders. His AGAs suck. He would say he's there to help, but doesn't explain well because he's afraid of "giving away the answer."

Unclear grading expectations. Everything you do is never right unless you have the key and write it verbatim. Never taken a class where I feel like effort doesn't lead to a grade. You'll get the grade he gives you. TAs don't know what they're doing and it's not really a fair class. Perusall is simply busy work. Doesn't help but does waste time.

Brother DeWall teaches some tough courses, but does his very best to break things down for the students to understand. He's good at answering questions as well.

Really tough graders. The professor does not provide a rubric for you to have in mind while answering the weekly group projects. TA's will find ways to diminish your work because "you did not explain well this or that concept" kinda thing. I love genetics and find the class material fascinating, but honestly hate the methods that the teacher uses

Bro. Dewall is an amazing professor. You can tell that he really loves what he teaches. The class itself is difficult, but he breaks down the material and makes it easier to understand. Attend his forums, they're very helpful. His graders are harsh, so make sure to add lots of details in the group AGAs. Exams aren't cumulative.

Of all the professors at Byu-I Brother Dewall has been my least favorite. Doesn't give students the benefit of the doubt, and doesn't care whether students get an A, B, or C, and that is reflected in the way he grades. I've taken multiple classes from him and this has been my experience both times. I'll never take another class from him.

Bro Dewall is way nice. Genetics is a decently tough subject but he breaks it down and makes it manageable. Really not sure why he has so many bad reviews. Do the reading he gives you. It's a pdf, 10-15pg, 2x a week. Group assignments on fridays are designed to be hard but the tests arent nearly as hard. If you need to take genetics, Dewall is good

Bro. Dewall has got to be one of the best teachers I have taken. Genetics is a pretty tough class no matter who teaches it. Bro. Dewall gives lectures so organized and I love all the colors he uses to thoroughly understand the material. The AGA group worksheets are pretty hard and is a tough grader with those. 10/10 recommend.

Brother Dewall is probably the best professor for this class. He didn't like how much info was in the text book so he made his own, with just necessary info. He draws a lot of pictures and explains everything really well. He writes the tests based on what he says in lecture. I would highly recommend him.

Brother Dewall seems like a nice person but as a teacher he is horrible. He writes his own textbooks and they are so unorganized and hard to read. His lectures are so slow and so boring and consists of him just regorgetating the material from his home-made textbook. I feel ripped off paying for my education and having him as a teacher.

Contrary to what has been said about his BIO411 class, it's great. There are no pop quizzes, he announces every single one. The class is quite easy if you pay attention to the lectures as literally everything on the test is talked about in class. The book isn't even important outside of getting you ready for the quizzes. Brother Dewall is great.

Professor Dewall is a very lovely man, however, he does not follow the school curriculum for Microbiology (at least when I took his class). This made it very hard to find help on the subject, as I couldn't consult any of the school's tutors.

Group-focused. You work on a weekly assignment and take a weekly quiz together. There's also a weekly quiz you take on your own. Quizzes/tests directly follow the reading but there's so much content which makes quizzes and especially exams very difficult. No comprehensive final thankfully. Exams on proctorio. Weekly optional zoom calls that help.

Honestly one of the worst experiences I've had at a class here. I tried emailing him and his TA so many times and never got a response. My group members tried reaching out and usually he responded to 1/10 emails. Constantly had to fight about the grade I was given to get points we were supposed to have. Don't take from him if you can.

It is all group work which is incredibly frustrating. The team worksheets are arduous and are graded harshly. Often I had to email about the grades and argue specifics. Brother DeWall is decently forgiving at least at the beginning of the semester. Exams are rough. Only take this class if it is absolutely required for your major.

Lots of reading. Group work is huge in this class, and I didn't like that he assigned groups like we're in elementary school again. He does lecture though and his lectures are great at helping to understand the material. The assignments were kind of tedious, both reading and group work, but they do prepare you for the tests. NO FINAL in the class!

If I were to go back in time i would- go to class and see if my group is competent. Yes- keep with the class. No- gamble and take it another semester. Class is entirely group work on packets mixed with constant at home book assignments that get old real quick. Quiz in class every other day. No final but 4 unit tests. Bro Dewall is a good guy.

Bro Dewall is very smart and particular about things, but kind. His lectures are pretty slow, but helpful and very detailed. He doesn't go over everything you need to know for tests/quizzes so read the book and go to tutoring. My only complaint was there is no late work/opportunities to re-do or show learning from mistakes.
