Fun Prof! He records and posts his lectures and even makes biochemistry sing!

Kevin's BB451 course isn't so bad...you just need to memorize the materal.

he's helpful in office hours and perhaps the most interesting of the whole biochem lot of professors. still hard, though--i mean, he wrote the book, right?

Very nice guy.

Good teacher, Tough Tests!! Keep up on the work!

He simplifies things wonderfully and focuses on the important details only. But his tests are not very well made and rather hard grader. It is no good going to his office!!!

he's very accomodating, and really likes what he's teaching. Doesnt hurt that he wrote the textbook either XD OH and he has everything automated for those who cant make it to class.

nice guy. hard tests. lots to memorize.

Man...this guy is hard, but he knows his stuff. Biochem. is a complicated enough course without a gifted professor, so it helps to have one who is equally good at the subject matter and at conveying the subject matter.

He's hard but is VERY willing to help you out!

He speaks very quickly and you must pay attention at all times during lecture, and write notes very quickly to keep up in the class!

Nice guy. Tough prof but explains things well and makes it interesting. Does ask 2-point questions about minor details sometimes, but 8-point questions are about main topics. Really wants you to succeed, offers to help you, very available for extra help.

I had Dr. Ahern for 4 different courses during my undergraduate years and he is by far the most dedicated professor towards his students that I have ever seen. He truly wants his students to succeed and is willing to meet with students at any time to assist them. A+++ Professor!

AWESOME! Do anything and everything you can to take this class from him! He is so awesome and just really wants to help his students out.

Great guy, gives you several options for learning the material and is VERY receptive to office visits. Take any class he teaches, you will be rewarded

Always knows what he's talking about, and ends the term with a song!

I love that he video tapes his lectures. Difficult exams. Quirky mad scientist professor of biochemistry!

Best professor at this university. He wants his students to succeed and is there to help. Class is hard but put the time into it and an A is easy. Take as many classes from Kevin as you can, every thing he teaches, he teaches well.

straight forward and to the point

If you can take classes from him do, you will learn things correctly and you will be responsible for knowing them but you will be better off having met Dr Ahern. He cares about his students and if you have a problem, he will help you with anything! I'm looking forward to taking more of his classes!!

This class was NOT what I was expecting. It didn't really have much to do with medicine at all. Mostly we just sat around and complained about all the ethically wrong things that happen in science these days. Kevin is a great guy who cares about his students, bu takes himself a tad too seriously.

Very willing to help students learn material, even outside of class time. Talks a bit fast and therefore moves through material at an incredible rate. Uses many aspects of learning to reach all students.

Awesome teacher. One of the best science teachers at OSU. I would say in my academic career at OSU he had the most interest in the success and lives of the students of any professor.

Amazing instructor! Smart and entertaining.. and for once you actually WANT to attend class. His exams are challenging so make sure you understand the lecture outlines he usually provides and you need to keep up BUT he's more than helpful. Just stop by his office and let him know who you are. I wish more instructors were like him

good guy

He makes a very hard subject very enjoyable and has a great sense of humor. his tests definitely aren't easy but he's ALWAYS available for extra help and loves to meet his students. this guy makes you feel like your tuition is very well spent. =)

This class was very good. I recomend that if you can take a class taught by Kevin. Someone mentioned that he wasn't very helpful durring office hours and I found this to be false.

The amount of material to learn in this class in insane, and Kevin expects alot from students, but he is enthusiastic about the topic and it can be a really cool class. But you will study like you've never studied before.

Kevin is awesome!

Great teacher, he help us understand the whole 23 chapters of the materials. He makes the classes not that hard. He is great teacher, easy to understand... KEVIN AWESOME.......

Excellent teacher!!! He makes you enjoy the subject

My favorite class of the term, always fun. Kevin has a great sense of humor and tries to make biochem fun/easier. It's a hard class, and he curves it, which helps a lot, and he's almost always available in his office hours. It's always worth your time to attend lectures - every once in awhile he offered extra credit to the people there that day.

He is an amazing teacher/person. But holy crap, this class has a lot of material. It's hard to believe how much stuff we covered when i was studying for the final. This class is a mother^%$&^%, hence the title. He is the best one to teach it though, hands down. I'm happy that he also does 451.

Whether or not you like him as a person, the guy is probably the best professor on campus. I know of NO other professor who truly critiques how they teach as much as he does. Everything he does seems very well thought out to best help the student learn and enjoy the material. Start studying on day 1! Posts video of previous lectures online :)

He is lovely. The material is very hard, but he does an excellent job of presenting it.

This class is hella easy in compared to bb490 series. the professor gives you everything that you needed, but the grading by TAs sucks. Kinda annoying when he kept using professional points against student. He got the enthusiasm towards some students and not others. you may feel rushed when u talk to him. short question test, so write fast & clear.

I think he is the best biochemistry prof out there - he is a great instructor and interesting to listen to. I actually wanted to go to class. He also videotapes his lectures which is wonderful - they should all do that. The class is hard but if you put in the time it is not that bad.

Kevin will not disclose how he calculates final grades, and he leaves 10% open for "professionalism points." Since TA grading is unreliable, you have to be skilled at demanding corrections without hurting Kevin's ego, or he'll dock you prof. points. The subjectivity kills. This guy makes me think twice about recommending OSU BI/BB to new students.

Seems very enthusiastic about the subject, but not terribly helpful towards e-campus students. Gives us the same syllabus as the in-class students (which is very confusing, since half of it doesn't apply) and occasionally some of the exam material seems to be covered in recitations...which we don't have. Wouldn't recommend taking it online.

Awesome teacher. He is really enthusiastic about the subject and does a great job making sense of it all. You get the feeling he could teach it without any visual aids or notes or anything. He really cares about his students. He has hundreds of them, but if you bother to establish a relationship with him he is very helpful.

He can be helpful but does often give off an irritated feel, which makes him hard to approach. You can skip class because he put the lectures on video, but it's all around easier to go to class.

One of the hardest classes I've taken, but one of the greatest professors I've had. He is dedicated, and provides many resources for your success (tapes lectures, posts powerpoints, provides list of key points, and sings in class!). If you need to take biochem, take it from Ahern!!

Took him for 450,451. Probably the hardest class I have taken at OSU mainly because there is just so much information. The material is interesting though and Ahern is effective at teaching it. If you have to take Biochem he's the best option.

Dr Ahern is a great professor. I truely enjoyed taking heis BB 350 class even though it was probably the harder classes that I have taken in college.

BB450 and 451 were extremely information-intensive and owned about 3 straight days and nights of my life before each test. However, Kevin gives students so many resources to learn from and I always found myself smiling during songs. Rewatch all the lectures, make notecards and get a study group. Extremely legit class and prof.

Kevin Ahern is a wonderful professor. This subject is HARD. Kevin tries very hard for students to understand and care about this subject. He makes lec videos if u missed 1 or want to refresh, has lecture outlines, lecture highlights, and sings metabolic melodies. How may professors u know that does all that? Just STUDY STUDY STUDY STUDY!!!!!!!

I couldn't help but notice the sour grapes comments below. There's no way this guy plays favorites and there's no way he'll rush anyone through office hours. For Pete's sake, he keeps more office hours per week than many professors do in an entire term. A great prof, in my opinion.

Best professor I've ever had at OSU. Period. Kevin is a breath of fresh air compared to most stuffy science professors who don't really care and insist on teaching in a monotone, uninteresting and non-beneficial manner. He is fantastic.

Kevin is the most committed person to teaching that I have ever met. He roots for every one of his students not only in their performance in his class, but also in their other endeavors. He seems like he knows every students name also! He is no push over though-his tests are very fair, consistent and HARD (they will cover everything he talks about)

Awesome....best professor I have had at OSU. Difficult class but interesting and fair. Kevin is available for help more than any other professor I have met. He even gave us his phone number to call him at home with questions. Be thankful that he is the one teaching biochem at OSU.

The class is just a "get to know the college/major" class so no homework/tests and only met like 5-6 times the whole term. A few guest "lectures" about travel aboard and things like that. I've had other interactions with Kevin that influence my opinion of him but based solely on this class he was good.

kevin's awesome, he gives you so many resources to study from that you have no excuse to say you had no idea what to study for. but make sure you do cause the subject is HARD and he WILL test you on every little thing he says (even if he just talks about the subject for a minute). study hard and you'll be fine! plus you sing in class!

Great teacher, great mentor. Ahern challenges you to become the best student and person you can be. He may seem kind of intimidating at first but if you have confidence in yourself to do well and show it, he will help you succeed in school and in the world like no other advisor/professor can.

Kevin is a very entertaining lecturer. He records lectures and posts them online, posts highlights and supplementary notes, and will NEVER ask you anything that he hasn't said in class. However, the sheer amount of material is painful. Go into this class expecting it to be your hardest class ever and you'll be prepared.

Great teacher, but a little weird. Likes to use songs to teach the material. Hard class, and you definitely need to study. He is great about adjusting the material to the speed of the class, he will outline what will and won't be on the test.

Didn't touch textbook, didn't attend required recitation but still got an A-. Ahern a is great professor, but his exams are pretty tough, especially during the summer when 10 weeks is crammed to 4. I can't speak for during the year, but during summer it's hard - it's not complicated to get an A, but it requires a lot of hours memorizing everything.

Very entertaining professor. Really enjoyed his lectures. Some of his personal policies seem a little silly but still a cool professor.

Kevin is the best professor I have had at OSU. He is very clear on what he wants you to learn and presents the information well. I suggest attending class even though he posts the lectures because is is easy to get behind. He is goofy, but it makes the class fun and interesting.

Everything I hope for in a professor: crystal clear, frank about what you do and don't need to know, and doesn't assume any background knowledge. Over-the-top in the effort he makes to provide a variety of resources and assistance. It's rare to know without a doubt that a professor wants everyone to succeed in their class.

One of my favorites. Loves what he does and it shows, he goes out of his way to make learning engaging and fun for every type of person. Nice that he records each of his lectures too! His lecture style reminds me somehow of an old-school preacher pacing up in front of the room.

EXCELLENT prof! He makes difficult material easy to understand, provides ample learning techniques, and is always available for help. Class is never boring, always interesting and even very fun!

Kevin is a GREAT PROFESSOR; however taking his course online is NO NO. The final grade is composed of 3 HWs (5%), 2 midterms (25% each), and a final (45%). The exam questions are VERY easy to screw up. Weird because I knew the material but failed a test. No way I could get an A or B so I withdrew.No room for error in his course..beware if you dare

Helpful and EXTREMELY passionate about the course material. Very challenging courses to take over a short amount of time (7 quarter units over 7 weeks, essentially a test each week with ~2 lectures per day). Would only recommend taking if one has 100% availability to focus on these classes over summer and no other academic commitments.

Kevin Ahern is a wonderful biochemistry instructor that goes above beyond any professor that I've ever seen. He will post all his lecture on Youtube and sing wonderful biochemistry songs with the class!! If you're interested in biology and chemistry he will not disappoint you!

Dr Ahearn is great! He records all his lectures and posts them on Youtube so missing class or needing to go over something again is not a problem. His tests are hard, but not unreasonable. He spends a lot of time clarifying difficult concepts and answering questions in each class so it's not like you are getting an overload of material.

I was lost in biochem before I listened to his lectures online. He made it fun & I actually learned something useful. Very talented professor. He's extremely organized, has a lot of free material and makes learning fun. I'm taking graduate level biochem at another university but used his lectures to learn & pass. My fellow students use him as well.

Kevin Ahern is a great professor and if you are interested to see what he is like go to Youtube and type in his name. He wrote his own textbook and he sings songs in lecture. My only complaint is that he is very busy. His office hours are whenever he is in his office but when you see him in his office he seems very busy.

I did not take his class, so I can't comment on his exams. I am from a different university. My own biochem prof are horrible and mean. I watch his youtube lectures and they are really helpful. Way better than my professor can teach.

Ahern definitely loves biochem and tries to make his students interested. However, I often found it hard to take notes in class as he went fast and the material was tough. He posts his lectures online which is very helpful to go back through and pause to get info. Tests are fair, but the class material is just hard in itself.

Kevin is a very skilled lecturer. He tends to have very fast pace Course,but the material is fair. He does provide various types of extra material like video and voice recordings of the lecture. If you want to ask questions I suggest you do not mention difficulty you are having in class but go straight to material related questions,

Really enjoyed this class! The lectures are engaging and Kevin is very knowledgeable. The material is tough, but biochem is a tough subject. If you watch the lectures, read through the lecture highlights, and dedicate time to familiarizing yourself with the material then you'll suceed in the class.

Let just say you better be well prepared for this class. You have to have mastered the concepts to do well on the exams. The multiple choice format is not like you would expect, but he has to make it this way since there is no paper pencil. You cannot put in medium effort and still get an A, unless it's your second go around!

Throw away your book, he does not lecture or test from it. THE HIGHLIGHTS ARE THE KEY TO YOUR SUCCESS. Not in the highlights? 95% chance it wont be on the test. Class goes way too fast to take good notes. I took 3 hours to watch each lecture video after class, and wrote down extremely thorough notes. I got an A both terms.

I took biochem at another school, but I used his online lectures a lot. They are great lectures and helped me so much when reviewing for tests. Glad they're public, they are very detailed and easy to follow, I'm sure I will use them again.

Really useful

Amazing teacher, made me really enjoy the class. However, tests are really hard. You have to put in a lot of study time to do well, but it is definitely do-able. He gives everyone a ton of time out of class to get help, and he wants everyone to do well and understand the material. Funny too! The tests are based off of posted Highlights not textbk

These classes are full of difficult material. I feel that Kevin did a good job at selecting the important stuff and structuring the material so it has better continuity. The exams are multiple choice, but do not be fooled they are extremely challenging. I had to study more than ever before to do well. Best of luck!

Kevin is very receptive to how the class is feeling. He tells jokes if he can tell that people are zoning out and tries different methods of explaining things if you don't understand, he is also very helpful in office hours. He provides videos of all his lectures and a free textbook online. Beware though, is tests are HARD!!!!

I cannot imagine taking this class from anyone other than Kevin- amazing job. All lectures are filmed, live youtube videos so you get the entire class experience. He films his review sessions and homework discussions. The textbook is great and FREE. He responds quickly via email. Expect A LOT of time watching lectures and studying for tests.

Am currently taking BB350 online from Ahern. I have to say, I am very impressed. The lectures are incredibly engaging and fascinating. He has a unique ability to break down the info so it is easily understood the first go 'round. The MC tests are challenging, but they are curved. Only take online if you are self motivated, because you MUST keep up.

Kevin is an amazing lecturer, if you can keep up. He goes way to fast in class to be able to take notes effectively so you are better off just listening and watching the videos later. Don't bother looking at the book since he posts what he wants you to know in the form of highlights. One of the best profs I've had in terms of teaching quality.

Kevin is a great professor and is incredibly intelligent. He may have heavy lectures, but he has to give us the material and I'd be hard pressed to find someone who can do it better and more enjoyably. My god does he have a lot of students sucking up to him though. Makes class go by a lot slower than it needs to.

I took the online 4 week summer version. It was definitely intense & you have to manage your time well. Not an easy class, but if you work hard, it is doable! Kevin was a great lecturer - he even has songs for many of the topics that help you learn things. I thought he made most things relatively easy to grasp considering the difficult topics.

I took the online class. As long as you keep up with the lectures, you'll be fine. The lectures move really fast so make sure you pay attention. All the resources you could possibly need are on his page (which also means he isn't very receptive to questions). Specific tests but it's all information he directly covered in the lectures and highlights

I appreciate his style, although many find lectures and tests to be challenging. He genuinely cares to deliver material that is understandable and by making his lectures, text, and other course materials all free and open he should deserve credit for accessibility of education. I had him for BB350 and am currently taking 450/451 online.

Phenomenal instructor! I had him for BB451, it was a very tough course but I have never learned more in my entire academic career! Tests are challenging, keep up with the material and ALWAYS look at the highlights and provided readings if you care about your overall success! He loves to teach, you just have to be willing to learn.

Kevin was by far the best prof I had in my undergrad. He absolutely lives for biochemsitry and you can tell. He puts so much detail and effort into all his lectures. As difficult as the topic was, he made it enjoyable and relatable. A lot of people dislike him because his tests are extremely hard, but that's how you retain the info. 10/10 professor

Dr. Ahern is knowledgeable of the material he presents. Though the class was hard, it is manageable if you read and watch the videos. There are few assignments and 3 tests amounting 95% of the grade. He does not grade on a basic 100/90/80, so there is curving. If you ask questions that are covered in his lectures or syllabus, he will not respond.

Kevin is what all Prof at a college level should be like. He really knows his stuff and really wants you to learn it. Its not just memorize the material, its understanding why it all works the way it does, which is the real reason we want to study it and utilize it for future discoveries. Yes, it is a tough class but it is well worth it.

Kevin is a great lecturer and his exams are very fair and representative of the information in his lectures. I was told not to take biochem with him but chose to anyway and think the class was really great. I love his lectures, and though your grade is only based on three exams, they are curved and I believe it is very fair.

Great teacher, but really hard exams that phrase questions like this, A) this B) this, and this other thing C) this, this other thing, and another thing D)this, this other thing, another thing, and one more thing E)this, this other thing, another thing, one more thing, and this extra thing

I liked his class b/c you have the ppt/outlines while watching the videos. You have to work though and you have to keep up. This is a hard class! Everyone got low grades on exams, but its like a sliding scale not curved but a weird way he grades it. I got the same mid D on all four my exams and came out with a B+ If you have self control youre ok

he's great
