Assignments are quite easy. Works a lot with computer animations in class. Homework is easy online stuff that takes 15 min to do, once a week. Read a new chapter each week on your own and he lectures. Definitely take notes while reading. Does a lot of cool case studies too on diseases. Very accommodating with extra credit. Tests are semi-hard

Great professor. If you're having trouble, go to his office hours; he's super helpful and really wants all of his students to do well. His tests aren't easy but again, go to office hours and he'll tell you exactly what to expect. Also gives plenty of extra credit and the other assignments aren't hard. Can't wait to take him again next semester!

Overall, great instructor. Lectures are clear and easy to understand, and power points are posted online. He holds longer office hours than any of my other professors, and is always willing to answer questions about the material.

Dr. Abreu is an amazing teacher. He is always available to talk in his office hours and gives plenty of extra credit (one day for just showing up). The tests are fair and easy if you come to class.

He seems very informed in biological concepts. However, when it comes to any diagram or mathematical thinking he falls. He does put trick you on some questions of the test.

Abreu has the reputation as being an "easy professor." He's only "easy" if you're not a diligent student. That is, if you study the hard concepts from his lectures, you're wasting your time, because he doesn't give you typical "application-type questions" that you'd see on the MCAT. In this respect, he's very "surfacey" and does not go in depth.

I think that he's really a great prof, took a really crappy bio class in hs but got highest marks on every exam.

Professor Abreu is a solid choice for intro bio class. His exams are mostly based on his lecture. So its important to pay attention in class and take good notes. He gives a lot of extra credit opportunities. However, his slides are sometimes disorganized and hard to follow. He records his lectures so you can rewatch them again which is helpful.

Dr. Abreu is such an entertaining lecturer. I loved his class so much and he is so amazingly fair. He will throw out a quiz question if it was confusing or unfair and he offers extra credit. Great teacher, great person, I am taking him again every chance I get.

Abreu is a great guy but a pretty mediocre teacher. He doesn't input anything into canvas or if he does the weights are all messed up so you're gonna be guessing at what your grade is the whole semester. Tophat sucks. His slides are garbage, just use the textbook. POGIL activities in class that are just busy work worksheets. Super guy chill tho

Abreu is one of my favorite professors at Emory. His grading criteria is very clear: 3 exams, final exam, quizzes (drops 2). He is funny and keeps lectures interesting. Pay attention in class because he tells you the things that are most important to know. Offers 1 index card cheat sheet on each exam. Multiple extra credit opportunities.

Abreu is an easy A for bio 141 + 142 IMO. Lots of assignments, extra credits, and weekly quizzes (mostly take home and you can drop 2 at the end). Exams are pretty straightforward and based on what he says in class. Only cons may be is that he is on the lazier side in terms of updating grades and never responded to any emails I ever sent.

Tests are easy compared to the other sections, which is why students chose Abreu. However, he is terribly disorganized: Doesn't post slides until you ask him to, never responds to emails, and office hours aren't great. You have to weigh these two factors when choosing. Genuinely cares about student success and is a nice guy.

Dr. Abreu doesn't answer emails most of the time, but his lectures are pretty interesting. He's pretty lazy and unorganized but his class is an easy A if you just study the lectures.

He showed up late sometimes and there would be technology issues here and there but I would recommend him to most pre-meds. His class is much easier than the other intro bio professors, so you have more time to study chem. The exams are multiple choice and he reuses questions from previous exams on the final. You can find the answers on quizlet too

Dr. Abreu is not a good teacher. There is not much to say other than he is disorganized and unclear with what he expect us to know.

Abreu is really disorganized, but he is committed to teaching. He holds review sessions prior to every exam rather than using the LAs to conduct them.

Whether you like Dr. Abreu's teaching or not depends on what you wanted to get out of the course. If you're seeking deep biological inquiry and discussion, you probably won't be satisfied (also bc 141 is an introductory course). He's the professor to take to have a well-rounded, basic understanding of bio.
