Dr. Arroyo is a great guy. He is from Puerto Rico, so yes his accent is still thick and he makes english errors. He does weekly tests instead of midterms. But he cares about his students and will help anyone he can as much as they need it. if you go to his office or the TAs then you will have no problem getting an A in the class. highly recommend!

If i could take this guy for every bio class i had, i would! He doesnt always explain things in great english, but he does just fine. If you attend class, and review his slides and go to the TA review each week, you dont need to read to text and you will ace the class. Seriously, i love this guy, take him if you can! You will learn bio with ease!!

Awesome teacher, really cares for his students and is willing to help. Read before you go to class and you'll understand the material. Put in the work and he'll help out with the rest.

I think this course is easy, regardless of who you take it from. Professor Arroyo is extremely nice and always willing to help. However, he assumes you read the chapter thoroughly or at least already understand the concepts and lectures accordingly. Really the only reason to go is to find out what you will be tested on weekly.

Dr. Arroyo is a very knowledgeable teacher. He does know his stuff but sometimes it seems hard for him to express what he wants to say in English. He always makes sure that all questions have been answered before moving on and he really does care about his students. His tests aren't written very well and we didn't use the textbook much.

Great professor. He really cares about his students, and wants you to get an A. He posts review slides online, as well as posting the daily slides. Going to class isn't mandatory, but it helps. Tests are not too difficult, and they are rather straightforward. He does have a puerto rican accent, but I find it rather easy to understand.

Science is my favorite subject, it is my thing. While the PD Bio 120 class from Professor Arroyo can be demanding and fast pace, he really wants you to succeed. He tries to make the class as easy and clear as possible but he does have an accent, If you have a hard time understanding accents I would not take from Professor Arroyo.

He is a very good teacher. Some of these other reviews are clearly by frustrated students. His accent is different, I wouldn't even describe it as difficult to understand. His presentations are NOT riddled by grammatical errors. He very much wants you to succeed. He has 5 grading methods, and he applies whichever would give you the best grade.

Great guy. His english is a little shaky, but he's not impossible to understand. Go to his office hours. He will likely give points back on tests and homeworks if you are polite and can argue your point well. He LOVES his students. Sometimes the test questions are confusing, but not enough to drop you a letter grade or anything. GREAT guy.

Great class. He has an accent that can be tough to understand sometimes, but he really wants to help. He sets you up to get an A with multiple grading procedures. If you work with him and the TA's, it's an easy A. If you don't show up to class, you won't pass.

Pay attention to what's on the slide and you'll make it. Tests are fine, final's a beast! He tends to talk really fast making it hard to take notes but reviews a ton so you learn! You do need to put in the effort; not an easy A.

Doing well on his tests is difficult. Half the test is trying to figure out what is being asked. He is extremely helpful, kind, and approachable. I enjoyed his teaching method which is information overload at the beginning of a chapter and then a lot of time reviewing the material so by the time the test comes you should understand most of it.

Dr. Arroyo is a wonderful professor. His tests are tough, but he gives you tons of extra help and lets the TA's see the tests before their test reviews. He uses a repetition teaching method which seems tough at first because it is fast, but don't freak out. He is really one of the best teachers here at BYU. Use your spanish with him. Go to class.

Good teacher. Every time I went to his office hours to talk about a test, I got points back so GO TALK TO HIM. If you make the effort he is very willing to help and wants to make sure you understand. You only need the textbook for the online quizzes due before class, but everything from the test comes from the powerpoints, which he posts online.

You won't regret taking this class from Dr. Arroyo! All his slides are posted online, and his lectures are verbatim repeats of the slides. He is the NICEST man ever, and he loves his students. TA's see the exams beforehand, so their reviews are a GREAT resource. Short, weekly homework assignment and online quiz open book plus a few exams. RECOMMEND

I took this class during the summer so it was pretty fast but it was still easy. If you get an A on the final you get an A in the class. It was really an easy class. Just study his slides and you'll do well on the tests. Also, go to him during his office hours and he'll most likely give you some points back on a test.

I LOVED this class. We had class twice a week, and the first class period was a lecture from Dr. Arroyo. The second class was us presenting on topics involving reproduction that interested us. I felt a lot of peace coming to class, and Dr. Arroyo was very good at presenting potentially sensitive topics with great care and love.

Nice guy. He'll go to any length to help you, and he gives you 4 options for grading in the class (different balances of homework and tests), so it's easy to get an A. His accent does make it hard to understand him sometimes, but I really liked that he posted all of his lectures online. I would take another class from him anytime.

He is not a bad teacher. Most of these reviews are written by freshman who are used to having A's spoonfed to them. This is college. Do your work. Learning doesn't end during lecture. 90% of it happens on your own, reading the book and reviewing concepts. I'd recommend taking PD Bio 120 from him.

Arroyo is a really nice guy and I learned a lot. He moves really fast in lectures and has a thick accent which was hard for taking notes, but he posts all of the Powerpoints online. Lots of homework, but it is easy. Tests are really straightforward. He wants you to know the material and works with all of his students to help them succeed!

seriously easiest class ive ever taken. all semester you just write 1 long paper which is most of your grade, most do well on this. other than that you just listen to lectures that you dont take notes on b/c theres no tests. once a week you write your feelings on a primary article of your choice. all must take this class to lighten your load

Hes a super chill and easy teacher. He really cares about kids passing his class. Really is involved with our tutors offered at chico, so if you struggle definitely go to tutoring or SI. Overall one of my fav teachers so far.

Great, easy class. Most everyone are seniors and all you do is go to lecture, read a paper (or an abstract) and write a half page on it for the next class, present that (1 minute) every other week, write one paper and present that (5 min). Just do the work and you'll get an A. And interesting stuff!

I LOVE THIS CLASS!!! The lectures went at a good pace but the professor is extremely engaging. There are reading quizzes and weekly homework that arent too hard and the tests arent too bad. He emphasizes students knowing how to apply information rather than just regurgitate definitions which I really like.

Professor Arroyo is one of the best PDBio120 professors. The classwork is very reasonable and tests are straightforward. If you're considering studying life sciences/medicine, this class will give you a great foundation. Dr. Arroyo is very approachable and easy to work with. He obviously wants all of his students to succeed.

Dr. Arroyo had great TA's and practice problems for this class. The material was sometimes difficult to understand and the class is fast paced. All the slides are on Learning Suite, review those like crazy. Arroyo is caring and genuinely wants you to learn. Some of the test questions were worded weird but go to the TA's, they saved my life.

Professor Arroyo is amazing! I am not sure why there were so many people that gave him such low scores! He takes time to go over difficult concepts and truly cares about his students and if they understand. He is accessible and has a great TA. Study, attend and you will be fine! He has a Spanish accent, but I understood him without any trouble.

Professor Arroyo cares a lot about his students. He teaches what is on the test and wants his students to succeed. His class is super interesting, he has a real passion for Biology, and he's always willing to slow down and answer questions when needed.

Nice professor, always willing to help outside of class. Class pace is really fast though, probably 70 slides a day. More info than you need for the tests in lectures, go to TA reviews and the class isn't bad at all.

Dr. Arroyo is one of the most caring professors that I've had. His is willing to work with you individually to help you succeed. As far as the class, the concepts aren't hard to understand and you could just review the slides at home since they cover all the material, but you still need to work hard since tests are tricky. Make a friend or two!!!!!

This Professor is great!! He is very clear about what is going to be on the test, plus the TAs get to see the exam before hand so GO TO THE REVEIWS!! He has a bit of an accent, which made it difficult for me to understand as first, but you can always look over the slides again or go to the TAs afterwards for clarification. Definitely recommend

Arroyo is honestly the GREATEST! He is truly one of the most caring people on planet earth. Yes he does talk fast and has a little bit of an accent but he posts all his slides on Learning Suite. The TA's are able to see the test so GO TO THE REVIEWS. His tests are worded a little tricky but as long as you understand the concepts you should be good.

I LOVE DR ARROYO. All the people here bashing him are mainly concerned with his accent, not his knowledge or teaching style. Despite having a different primary language than English, the man is HILARIOUS, teaches well, and has a great class set-up. You'll fall in love with the man if you give it some time and try in his class I promise.

He know his stuff, teaches it well, and provides every opportunity for you to get the grade you want. I got my first %100 on a midterm of his, so his class is very doable.

Dr. Arroyo wants everyone to get an A and uses four different grade systems to give you the highest grade possible. If you go to the TA reviews, they will tell you exactly what is on the test. Attendance is mandatory, but the lectures are interesting so it's not bad. Dr. Arroyo is super caring and the best PDBIO 120 professor!

Prof. Arroyo is pretty great, and very willing to give As. He has multiple grading strategies (with differently weighted categories) and will give you the highest score possible. Funny guy, attendance is mandatory. Totally willing to let you reopen assignments if you forget them and are being otherwise consistent in the class.

Dr. Arroyo would be better in person and not online. But he's very willing to talk through things in his office hours if you don't understand. He cares a lot about his students. He talks fast in the lectures, but again if you don't catch it you can go to office hours. Plus TAs review everything weekly. The TA's could see the test before hand too!

Professor Arroyo is definitely a great professor. Because of his accent, his lectures can be a little harder to understand (just don't play them x2 speed). He definitely cares a lot about his students and is willing to do whatever he can to help them get an A (he will change the weight of assignments to higher your grade). Definitely recommend.

I was surprised to see many people gave Dr Arroyo bad reviews. Hes a great professor. He does go through the lectures fast but I never had a problem with that. He spend an entire week reviewing for a midterm. Ive never had a profesor that did that. He really cares that you understand the material. The tests arent too hard. Guaranteed A!

Dr. Arroyo is a great professor, his tests are not hard and everything you need to know is in his slides. He is also super funny and his lectures are interesting and he truly cares about his students

Dr. Arroyo is awesome. He knows his stuff, and he is very personable. He will never ever fail to help a student in need. Lots of people say he lectures fast, which I won't deny, but I didn't have too much trouble keeping up. Plety of ways to get help from him and his TA's. I would take a class from him again.

DO NOT BUY THE TEXTBOOK. Biggest waste of $100 I've ever spent. There's a super easy homework assignment once a week, and EVERYTHING IS IN HIS SLIDES. Like I'd do about an hour a week and pretty much commit the slides to memory, and then get high 90's on his tests. And that's it. Seriously, a piece of cake.

Dr. Arroyo is a great professor! Definitely had to put in work outside of class and go to the TA's to understand the material. I felt like I didn't fully understand it until right before the test but then it clicked. He goes a bit fast but will slow down if you ask. He does great reviews for the tests. Barely any homework.

Professor Arroyo really is difficult to understand and he moves fairly fast, but he doesn't cover that much content each lecture. If you can't understand him, then just read the textbook (readings aren't necessary if you attend lecture). He cares a lot about his students & the exams are very easy w/ surface level questions. No surprises.

Dr. Arroyo cares so much about all of his students. Cell 120 by nature requires you to understand many topics and Dr.Arroyo was able to cover most things in class. He and the TA's will be happy to help you at any time. He also makes the lectures easy to digest and is a pretty funny guy. Class is easy but I wish I would have stayed on top of my work

I thought he was a very caring professor who genuinely wanted his students to succeed. He bases all his test questions off his lectures, so make sure you go to class. The TAs were incredible.

Dr Arroyo wants his students to succeed. He is funny, kind, and spiritual (every class began with a prayer and spiritual thought). TA reviews were built into class time. You will enjoy the course and do well if you keep up with the readings and pay attention in class lectures.

Dr. Arroyo was brilliant and extremely kind. However, the threshold to get an A in the class was 96% which frustrated a lot of us. His tests could also use a quick review from the TAs or something because a lot of the time the questions were worded very poorly or straight-up gave you the answer. The study guides were useful and TAs were flexible.

Dr. Arroyo is a super caring and fun professor. He really wants his students to succeed, and he often reviews material in class to help this happen. The online homework was sometimes confusing and did not feel helpful in preparation for the exams, but otherwise, I really enjoyed this class.

Tests for this class were AWFUL. Repeated questions, grammar and spelling mistakes, and most questions are "choose the best answer". The grading is also heavily based on the tests. The TAs were also not helpful and often made things more confusing. Dr Arroyo is a great guy and is super nice but this class should not be taken as a general!

Dr. Arroyo is the best professor I have ever had. He cares so much about his students and he is an excellent teacher. He is hilarious and I loved his lectures. Easiest A of my life. He did leave the answers in for a few of the questions on the final, but the test was so easy that it didn't make a difference. Highly recommend.

He is a really nice guy and really care about the students. His accent makes him a little hard to understand at times especially when he is going fast. The slides are the key to the tests, and if you just learn everything on the slides you will do well. He grades really easily and will pull different grading strategies to give you the best grade.

Dr. Arroyo is fantastic. He clearly knows biology and is really passionate about it, and he cares so much about students and is accommodating and kind. Definitely one of the best people and one of the professors I've had at BYU. Lectures go really fast so be prepared, and organization is sometimes not perfect, but overall Dr Arroyo is amazing.

Dr. Arroyo cares so much about his students its amazing! He is so encouraging and will walk you through anything you don't understand. I met with him multiple times this semester and all he wants to do is make sure that you are doing well in and especially out of class. I love Dr. Arroyo, and would tell anyone to take him if they have the chance!

Dr. Arroyo is such a nice person, he is hilarious, which makes his lectures enjoyable. But I think the tests are way too easy, too many people get high scores; and there are some occasional flaws in the questions.

Dr. Arroyo is a very caring professor! At first he can be a bit difficult to understand, but he will answer any questions you have and offers lots of worksheets and review/question days. Would definitely recommend attending TA office hours and exam reviews to prep for the tests. Lots of memorization, but a doable class

Dr. Arroyo is one of the most caring professors I have ever taken a class with. He knows the type of content that he teaches for an entry-level class like this and strives to simplify it as much as possible and he will go out of his way to help YOU be successful. Some freshmen kids mocked him in class, but that's just their racism showing off.

I actually really liked Professor Arroyo! He tended to rush through content because there's a lot of it, but he makes that up for giving practice days and review days for harder content. He's also willing to meet outside of class, good at responding to emails, and his TAs were amazing! Definitely recommend, but it is just a hard subject in general.
