A decent guy, but a crummy teacher. His lectures are disorganized and solely from power point. This makes it very hard to pay attention and get something out of lecture. Also, no HW. This might sound good, but he doesn't give any optional problems either. Despite grading gimmicks (bonuses, dropping lowest test, etc), final grades seemed harsh.
Dr. Loy is the best proffesor ever. He posts all his lectures online. A lot of the questions come straight from the homework. Exams are not that difficult. He is a fun and easy professor. I highly recommend taking his class
Smart guy but crummy teacher. He loves to ramble on about weapons and explosives and useless inapplicable applications for what he teaches us. Quite boring at times. He is rather amusing but in an extremely creepy way. He will help you if you need it but be prepared to deal with his breath that wreaks of coffee. Mediocre teacher to say the least.
Dr. Loy is an intelligent guy that knows what he's talking about, but his lectures aren't very thorough or crystal-clear, but they are very amusing on some days. He's a pretty harsh grader on exams, also.
He is a somewhat interesting person, but not a good teacher. If you are good at teaching yourself or learning from another source (teachers, tutor, etc.) then you may be fine. Organic Chemistry requires a lot of practice of problems, however he teaches just from powerpoint. Some of the other professors write things out so help you learn.
very nice guy, explains things very well one-on-one after class or in office hours (bring SPECIFIC questions or reactions - don't expect him to reexplain an entire topic). very DULL lecturer. book was very helpful because it is so hard to pay attention to him. gives lots of practice problems and tests. homework is 20% of grade :) dry sense of humor
Smart guy but you should not have to attend his office hours to learn the topics. They should be taught in class. He spends some time cracking jokes that nobody laughs at and spends the rest of the time talking about explosives. If you like teaching yourself difficult material, then take him.
Dr. Loy is hilarious. The first test was extremely easy. The second test was difficult; 50avg. However, he wrote another test (even though we were only supposed to have 2) and let students drop their lowest. Online hw worth a test grade. He gives extra credit. He is approachable/helpful but you HAVE to study & work hard... This is OCHEM after all:]
He teaches only from powerpoint and has almost no examples. Sometimes funny because he is NOT. Did not learn anything from him. Take McGrath or Spurgeon.
Powerpoint slides were useless most of the time. Learned more about the 200 things that can kill you, but not too much on ochem. Learned most of the material from the book. Discussion sections were more useful than class. Tests seemed easier compared to other profs, but again, not much is really learned. I would suggest going to his office hours.
Dr. Loy knows what he is talking about. He loves to ramble on and on about poisons and weapons and all of the great things we will learn in p-chem and chem grad school. Time is definately better spent not attending class, perhaps attending a Spurgeon lecture instead, because his powerpoints do not help much. 53%avg for 2nd test and 44%avg for 3rd..
STAY AWAY unless you like to teach ochem to yourself.
Dr. Loy teaches this class as if it were a higher level review of organic chemistry. He loves to talking about polymers/things that can kill you/p-chem/chem grad school rather than properly enforcing concepts. He isn't a very good teacher, however, he is helpful in office hours. I wouldn't recommend this professor.
Ended up teaching myself organic chemistry for most of the semester. Found lectures to be pointless since all he did was copy and paste elements from other professors lectures and skipped over half of them without even explaining information. Nice in office hours but otherwise unhelpful the majority of the time.
Loy's class wasn't easy but i have to admit the guy knows what he's talking about. Even though his lectures do consist of power points, it offers a unique opportunity for you the student to study outside of class using easier material than the book offers. He offered the class every chance to get an A - extra credit, extra test,curving:take him.
Ochem cannot be taught through a powerpoint but Loy did that the entire semester..which is why only about 60% of students showed up. Read the book, but even better..don't take him. Spurgeon is so much better!
I actually really like his course. He is a breath of fresh air when you compare him to Mcgrath/Spurgeon because he actually cares about his students and his exams are not impossibly hard. You really have to know what to take away from his lectures though. He goes into a lot of trivia, which is very interesting but it's not stuff you need to know.
This class is surprisingly easy to get A in. Just try to get above average in all the tests, do the homework, and make sure do do the extra credit. We were given 100pts extra credit that helped me get an A when I was averaging 60% on tests.I didn't really learn anything in class because its really hard to learn ochem with ppts.I taught myself ochem
If he teaches directly from powerpoints, and the powerpoints are literally just images and text from the textbook, what's the point of even going to class? I taught myself OChem this semester.
If he teaches directly from powerpoints, and the powerpoints are literally just images and text from the textbook, what's the point of even going to class? I taught myself OChem this semester.

Honestly, this is the worst class I have ever taken. I am a great student, and I had to teach myself ochem. STAY AWAY!!! You might think that his tests are easier, but only the first test is easy. And, the second test is pretty easy. But, do not let that fool you about the other ones.
Out of all the organic professors at the UA, Loy is probably the easiest A, only because he offers about 100 points worth of extra credit. However, if you actually want to LEARN organic chemistry like for the MCATs, you probably wanna stick with someone else. He taught from powerpoint, you'll end up teaching yourself. Not recommended.
I think Loy is a great organic chemistry teacher. It's true that he uses powerpoints but he explains everything well and writes LOTS of important notes on the board. He's really helpful in office hours as well. Not sure why everyone leaves bad comments about him...these things aren't true. If you want to learn ochem AND get an A, take Loy!
Professor Loy has an odd sense of humor, but he is actually pretty funny. Everyone who says his class is hard just didn't study enough. He gives you practice exams and problems which help a lot, and he is very nice in office hours.
He cares about his students, but is not very good at teaching students Ochem (ppts are not helpful so no point in going to class). He is funny however, but you will end up teaching yourself, so if you can do that go for it. Gives E.C. but in the end that does not matter because you have learned nothing.
Not the best teacher, but if you ask questions he is very good at explaining. You can't expect to learn everything in class, you have to study or else you will fail his tests. Mange your time, and his class is great. His lectures are very entertaining
Looking to be miserable for a semester? You've come to the right professor. You'll end up having to teach yourself everything because he'll just read off of slides he copied from a different school. Going to class is completely pointless.
Worst teach ever. Koerner was much better at teaching Ochem, but he doesn't teach second semester. I HIGHLY recommend you take any other teacher other than Loy. He goes word for word off the powerpoints, which is ver batum from the book. Teach yourself, go to preceptor hours, cry, you won't pass any other way.
WOW! what an absolutely terrible professor. Never in my three years at the U of A have a had such a bad teacher. Who teaches ochem with powerpoint? I really think that you should take whatever other teacher you can. Seriously this class has been made impossible with Loy.
Just because Dr. Loy doesn't hand you half of the exam prior to it like was done last semester, doesn't mean he's a bad teacher. Tests are very fair and since we're IN COLLEGE, learning how to read a text book is probably a GOOD skill to have, Dr. Loy is a good professor who will actually teach you a lot once you stop whining.
The lectures were awful, he makes Organic Chemistry so boring and it is almost impossible to not get bored in class. Furthermore, his tests are pretty hard. I would recommend taking anyone but him!
O-Chem must be really hard so that's why he has bad reviews... He made MSE331 a blast. He is really excited about everything he teaches and makes it very interesting. Funny guy. Personally, I never pay attention in lectures, but his were interesting. I aced tests just from studying his slides that he posts: never opened the book.
Dr Loy is one of the most brilliant people I've ever encountered. Quite unusual sense of humor, which I found pretty hilarious. His lectures are not the most exciting ones, but pretty good overall. Helpful to students and explains things well. Ochem can be hard, but if u can't make it thru ochem, there is just no way u'll survive in grad school
If you can't pull at least a B in this class, give up on med school or grad school because you wouldn't make it anyways. The tests are identical format/question types to the practice. 200/600 pts of unlimited tries on hw. Compared to McGrath (impossible) and Koerner (you actually have to try), makes ochem a total breeze. Very helpful in office hrs
Loy is a pretty sorry excuse for a teacher. He's an okay person, but you really have to struggle with the material on your own and read the book in order to pull anything out of this class.
Shows ochem on ppt, which is pointless. Almost no one went to lectures, and rightfully so because Loy doesn't teach, he repeats someone else's slides he posts it on his site anyway. His exams are easy and he gives SO much extra credit. I needed less than 30% on the final to get an A. You teach ochem to yourself. Get Koerner, he ACTUALLY teaches!!!
Terrible teacher. Why are such teachers at good universities?
Dr. Loy's class is awesome and easy. He really is trying to familiarize you with the material more than teach it though. Toward the end of the semester I stopped taking notes on the class and instead wrote all the funny(and morbid) one liners he had and got a full page each class. Tests are easy, just study the study guides he posts.
Awesome teacher! If you have to take organic chemistry and you want to actually learn the concepts, then take Loy. He is extremely helpful, kind and respectful. It is not an easy class and you will have to work very hard, but Loy is fair and truly a great teacher! Only good ochem experience I've had.
Pretty cool guy, always includes humor into his lectures. Everything you need to know for exams are on the power points he puts up and they're pretty straightforward.
Dr. Loy is a nice guy and he is very smart when it comes to Chemistry. But, he is not teaching material at all! He uses powerpoints that are not even his own lectures to present. So if you want to teach Organic Chemistry to yourself, than this class is for you. If not, do not get LOY!!
Dr Loy may not be the best prof in lecture but he explains everything very clearly in office hrs on a one-on-one basis. He is very smart and if you are willing to go to office hrs, you will learn a lot. I def learned more in his office than by going to Koerner's lectures to supplement Loy's lectures. Overall, not a bad prof and a nice guy.
Dr. Loy is a nice guy and he is very smart when it comes to Chemistry. But, he can no teach! He uses powerpoints that are not even his own lectures to present. So if you want to teach Organic Chemistry to yourself, than this class is for you. If not, do not get LOY!!
High intelligent but can not teach anything. You will teach yourself everything. Discussions are the only part of the class that helps. He gives extra credit but it really does not matter since you pretty much learn nothing
Absolutely awful teacher. He does not make his own slides, and although the slides are from the book, he does not follow along with the book. He is the worst teacher I have ever had in my life. His tests are not consistent with anything. He may be smart, and funny, you will fail all of your exams. Nightmare of a class.
One of the worst professors at this university in my opinion. Do not get him.
lectures were not very useful. His discussions were really good though. He uses power points to teach; you do not really need to go to class. I learned all the material aside from nomenclature from the book. He is really knowledgeable but not the greatest lecturer (1 on 1 he is really helpful though). I thought his tests were fair but tough.STUDY
Loy is not as terrible as these comments would lead you to believe. His tests are entirely nomenclature and reactions, and he gives you the nomenclature and reactions that you need to know beforehand. Also offers a ton of extra credit on sapling and exams. There are only 3 exams and a final as opposed to 4 and a final with other professors.
Loy may be one of the worst professors I have ever had. He refuses to actually draw/write anything himself, and relies strictly on powerpoints that are direct copies of the textbook material. His exams are extremely difficult with nomenclature and reactions that you have never seen. Do not take him for Ochem!
I am a good student, not going to lie. I study hard, and I love OCHEM in general, yet I had a hard time in this class. I feel like some of the nomenclature he puts on the test is kinda random , and some times there are reactions on the exam that are not in his ppt or book. Hes nice, but not the best teacher. He is approachable too which good.
terrible class. if you can take another teacher, then take them. his tests are incredibly hard and he never teaches the material. most of the learning is from the book so if you're good learning that way then you will be fine. he is a great person and approachable when you have a question but he is just so smart that forgets that he needs the teach
I don't know why everyone is complaining. Dr. Loy probably was the easiest 2nd semester ochem lecture out of all the other professors. Read the book, go to his office hours, and study the practice exam.
Dr. Loy is hilarious. If you really like ochem and did pretty will first semester then you'll enjoy his lectures and find them pretty helpful. Go to his office hours, he's always willing to help and he really wants to see students succeed.
He's not the easiest to understand, considering he goes off on tangents constantly, but he's funny and very smart. You can get away with not going to class and studying on your own instead. TONS of extra credit. Office hours are useful.
Dr. Loy is great. Funny guy and interesting, offers a different perspective than most chemistry professors due to his background in engineering/synthetic polymers. Good professor for Chem E students. I enjoyed the class!
This guy has real life experience. Organic chemistry is not a fun topic, but he relates it with real life. At first i was scared of this class, however, he has office hours where he will tell you what to expect on exams and how to study. He is there for his students and tries his best. Very funny guy btw. The professor isnt hard, the class is.
Dr. Loy is one of the best professors I've had the privilege of learning from. He teaches MSE 331R with years of experience working with materials. He focuses on what you need to know as an engineer and skips the bullcrap. He does his best to keep the class interesting with jokes, and myself and colleagues loved every second of it. Great class!!!!
Dr. Loy has homework worth almost 60% of your grade which not only cushions your grade, but helps you learn by giving you something to practice. OChem is not an easy subject by any means, but Dr. Loy makes it manageable and stress-free. Tests are very similar to practice exams. Lectures are fantastic and he has a sense of humor.
Best teacher I've ever had. 60% of the class was homework, so I only needed a 75% to get an A which on the tests (which also have 10 points extra credit). The averages are relatively high in the B and C range for organic chemistry. He is extremely interesting and makes the class fun. Easiest A I've ever gotten and it was in OChem.
You won't learn anything, so if this is not your last class in chemistry do not take him! however, this was my last chemistry class and I learned absolutely nothing but got a B+ so there's that. Good luck!
I've never laughed as much in lecture has did in this professors lectures. Grade scale was done in 15% increments (85%-A,70%-C .. ). Tests were 75%. 1 test grade dropped. Tests were all multiple choice with a short answer question or two mixed in. Extra credit as well. Cheat sheets on all but the first test. Helpful in office hours. Very enjoyable.
Dr Loy was a good lecturer with a great wit. Sometimes he'd get a bit off topic, but he usually roped it back. You can really tell that he cares and knows about what he's teaching. I'd love the chance to take another class with Loy. He was really understanding to any unforeseen issues and genuinely just wants to help students do well.
My favorite teacher. He was hard to get ahold through email but he is dedicated to his work so if you stop by his office he will most likely be there. I am prepared for ochem2 and learned a lot by him. He is very smart but understands the stress for students & is good person unlike many other science professors here. HE'S THE BEST. RECOMMEND 100%
If you're looking for an easy A in O chem, Dr. Loy is your guy. On the teaching side of things, he's not that great. He is very smart, but goes on tangents a lot and make it hard to concentrate. You really don't even need to show up for class, but you kinda gotta teach yourself ochem lol
Your grade is based mostly on homework, some are reading assignments which can take a while but always get 100% if you do them. One of the two exams are drops and then a final, there's a curve worked into each exam. You have to teach yourself if you want to really learn the material but it's an easy A.
Dr. Loy is kind of all over the place. He's a good guy and really wanted to get everyone interested in 3D Printing. Do good on the homework, try really hard on the papers and you'll totally pass. I would not recommend this class if you don't have an engineering background. Many struggled but thankfully they graded easily.
The class is mostly self-directed, with office hours/class time used mainly for asking questions to Prof. Loy. He offers extra credit and is very accommodating with the homework and exams.
There is a lot of mc/fill-in-blank homework in the textbook but worth it for self-learning plus 100% once you complete it. Do the practice test and you will make a good grade on the exams. Prof is available with office hours used to ask questions on assignments. Extra credit is also available. Funny man, makes him understanding for ext. Great!
HE IS THE BEST!! So funny at office hours. Sweet and caring. I took fully online OChem, lots of smartbook topics but he is very accommodating to all his students and ready to help as long as you show up. He even gives random extra credit to be nice. He really does care and knows his stuff!
Best chemistry professor I have ever had. He has weekly lectures, and there are 12 HW assignments over the course of 16 weeks. There are two midterms, and the lowest one is dropped at the end of the semester. There is also a final exam worth about 40% of your grade. He offers lots of extra credit, you just have to pay attention to announcements.
The best professor and an easy A for OCHEM! Offers tons of extra credit and always curved the exams. The homeworks were graded on completion rather than correction and you can pretty much work at your own pace for the course. 12 homeworks, 2 midterms (1 of which gets dropped), and the final exam.
It's an easy A for a class that absolutely shouldn't be an easy A. If you're taking ochem just to get it done, go for Doug. If you need to go on to ochem II, are in a major that will build on ochem, or just actually want to learn the material once for retention, he is NOT your guy. The exams pull from material from chapters you haven't learned yet.
He doesn't teach. He spends class talking about useless things that are not on exams. His office hours are not helpful either. He has a hard time explaining anything. The only way I did good on exams was by going to SI sessions every week, and he allows cheat sheets. Do not take if you have to take OCHEM2 because he doesn't teach mechanisms.
CHOOSE SOMEONE ELSE! 1) If you need to know this content for 241B, he's not your guy because he doesn't teach. 2) If you have a heavy course load outside of OChem, he's not your guy because you have to teach yourself OChem. 3) If you want a class where attendance is not required, just take an online course or go to Pima. Because it'll be the same.
Told us on the first day that he was not going to teach and that we should come to class already knowing the content. I just taught myself with the textbook and SI. Fairly easy A due to the way he structures the course but I don't recommend if u have to take 241B or the MCAT.
This class has 12 modules hw(100 points) on McGraw-Hill Connect ,2 exams(100 pts each, lowest gets dropped), a final(200 points). Passing is 240 points. It is very doable. I spent barely anytime on this class and passed w/C. If you want to learn, don't take this class. Don't email him, do yourself a favor and go to his office.
It was hard to learn from the lectures as they were not broken down to a level many students could understand. Using outside resources is most likely the only way to get a good grade in this course unless you're naturally good at chemistry. Pretty nice professor though and he did make study guides that were helpful for the exams.
taught nun new til the last month they literally THROW like 100 reactions at you out of nowhere and expect you to memorize them. Homework helps a lot but you teach yourself for sure! I only got an A cuz I did priv tutoring & all hw. his OH/lectures don't help tbh so I stopped going or watching, SI sessions help/are good but not good enough.
Horrible lecturer but also a super easy grader. He taught me absolutely nothing and I learned everything from the textbook but he weights homework pretty heavily so it pads your grade even if you do poorly on tests. On day one he said he would not teach and to learn the content before coming to class so I never bothered showing up after that.
This class is very easy. Sadly will probably not prepare you well for 241B, but is an easy A. The key is to be on top of weekly homework problems, and use the study guides and practice exams to your advantage. No reason anyone who is giving effort shouldn't get an A
he's a nice guy, just not good at teaching. If you don't have time in your week to attend SI, don't plan on doing well. You need multiple different avenues of supplemental instruction to do WELL in his course because close to nothing is actually explained. Just lots of talking about chemicals and how they'll melt your skin, not exam content.
I love Dr. Loy. He won't prepare you for Ochem 2 but it was an easy A for Ochem 1. There were only two tests and one gets dropped. He also gives a 10 point extra credit on each test that is usually easy. The practice tests are almost exactly the tests itself. I recommend especially if you have other hard classes to take.
DO NOT TAKE LOY! I was doing very well at the beginning of the course. 90 on the first exam but not because of anything Loy did. Lectures are useless, you need to teach yourself and it's very hard material. Bombed the final and tanked my grade which was worth 50% of the grade. Whole department is horrific. I worked so hard to do well for nothing.
He CANNOT and SHOULD NOT be teaching a level 200 course, he cannot explain basic concepts to save his life. He loves going on weird rants and wasting class time and his lectures don't make any sense. I tried to go to his office hours, but he wasn't where he said he would be. the actual course lode is pretty light but expect to teach yourself.
The class average was a 56% on the final exam and it was worth 50% of the grade. You have to teach yourself everything and going to lecture is not worth it becauseof his off topic rants. There is extra credit but it doesn't help . He's a nice person, but if you can I would recommend someone else so you can preserve your mental health.
