A great teacher. Really explains things well and gave me a wonderful beginning foundation in Chemistry.

He tells a lot of deadpan jokes in class, and perhaps those who don't like him need to not take everything so seriously. I am no science major, but I am rarely confused by what he says. My errors cause the most trouble for my grades.

Very knowledgeable and helpful, seems strict initially, but dont panic. He gives about 10-12 points worth extra questions on each exam, but scores it for 100. So its like extra credit. He makes Chem as easy as possible. Plays 97.7FM in the lab! rock on!

Nice guy but he only knows how to explain things 1 way and if you dont get it you're out of luck. His tests are very cut and dry and make up most of your grade. The final is a HUGE percent of the grade. Beware! If you're not good at science dont take him.

He was a great teacher and was very helpful. I enjoyed taking his class.

good teacher.i learned a lot from him.he shows a lot of care for his students and is very available to address any questions you should have.He grades fair.His tests are challenging, but you learn the material well as a result.

He explains things very well. Do the work and you will do well. I think he does care about his students. I took his class over a year ago, and just yesturday he passed me in the parking lot, and stopped to chat. How many ex-prof. remember you?

The course is very difficult but he uses fun examples. I actually learned some chemistry!

Verry good teacher, actually he is the best Chem teacher around. He is down to earth and easy to approach with questions. He is very hard and presents his students with a challenge, but if you keep up and do your work, you will do fine.

Harrison is absolutle GREAT w/no doubt!I took him 4 summer & got 84% B!He grades easy & gives u a curve!No extra credit. WARNING, there is a lot of studying.I went 2 tutor almost everyday after his class 2 refresh everything i learn.As long as u attend his class & go 2 tutor, Im sure u'll do fine.

Took intro to chem and then O Chem with him. O Chem was a hard class and he wasn't so great at explaining it (though he tried). On the plus side, great personality, humorous, and great to look at to pass time by. Can you say hottie?

He was awesome at explainging chem. He was hard, but he made himself completely available for help. He made an effort to get to know us and come to us if we looked confused. I would take his class again anytime. Come to lecture and ask questions, he makes you feel comfortable enough to. Great teacher, one of the best I've had a west valley.

very good teacher, keeps you interested in the class. funny examples. take good notes and ask questions. i highly recommend taking chem with him if possible.

He's a very nice, funny, friendly professor. Very approachable, cares a lot about his students. Likes to get to know you. Very cute when he talks about his daughter in class. That being said... VERY hard professor. Do not take in conjunction with any other work intensive class. You will HAVE to put in tons of time.

he is one of the best teacher , i ever had. the tests are sooooooo!!!!! hard.i love his teaching style and his test.

Took him for both 12A and 12B and although he tests hard, he's such a great guy/ teacher. He just makes sure you know your stuff.

He is a great teacher. His exams are very very difficult but he is so helpful and his lectures are very clear. He is always there to answer questions.

one of the best teachers ever.He is always there to help.He cares alot about his students and makes sure they understand the material real well.Loves chemistry.VERY FAIR GRADER/TEACEHR.NO matter where and when u catch him during the day,he is willing to help u.Athough his exams are hard, but i learned alot.

Dr. Harrison is by far one of the best teachers that I have had. The class is not a joke, and the exams are difficult, but he teaches with enthusiasm and he knows the material REALLY WELL! He is always willing to help whether it is during his office hours or not. He is a fair grader and his lectures are very clear. I learned a lot from this class.

His tests are hard, but you learn a lot. He is a great teacher! He knows a lot about ochem! Just make sure you study study study...

by far the best teacher i have ever had. he is helpful, clear, and his lectures are awesome. he is a very fair grader as well and isn't picky about labs. wonderful teacher! take ochem with dr. harrison if you want to understand chemistry!

This is a hard class but he is a great teacher. He really wants his students to understand. He also gives out practice exams which really help.

He really helps if you have questions. His office hours is wonderful, you can find him very easily. Chem is not an easy sub. but w/ him, it could be easy. Study and attend every single class. He really helps!

great teacher, the practice exams are a great study tool. it was a wonderful class.

notes can be a little disorganized, but in general an excellent teacher. Makes class fun with funny stories. Office hours and practice exams are great, and he really does want to help you if you aren't doing well. Tests are HARD so be prepared and he is a pretty tough grader on everything. DO NOT miss class you will get so far behind.

Awesome teacher. Love his stories! He's funny and really great at explaining fairly difficult concepts. Plus he wears great shirts.

he is very helpful and he is always in his office..his tests are not hard..just study the lecture notes you will be fine

He is such a nice guy. He has a really organized class. The way he teachs is interesting. but u should take notes when he is teaching because all he wants in Quizes & Exams are among those subjecs. He likes his job and so his students.

his class is hard in the fact that his lectures aren't the easiest nor most interesting to stay awake in. he is a funny guy tho. lab you each work individually, but sometimes all you do are hmwk problems, check them off, then leave. go to his OH to chk hmewk/labs to get 100% b4 turning in.

I really don't see what everyone is complaining about. This is Ochem, of coarse it's hard. Prof Harrison is very passionate, helpful and approachable. If you have hw or labwork that's due, go to him before class and he gives you the answers. The material goes by fast, but he is as lenient as he can be while teaching you the subject. Work for it.

I've had Dr. Harrison for Ochem 12A and B and I have to say he is the BEST Ochem professor you can get at a community college. He will prepare you for university level classes. It is hard to follow him sometimes in lecture but he is ALWAYS willing to help you during his office hours, but you have to put forth the effort. Great humor and stories.

Lectures were ruff since he doesn't give enough examples to understand how to do his homework, BUT Go to his office hours he will pretty much give you the answers. His exams are way harder than his homework, so be prepared. Labs were fun, but be sure to do your experiments right as well as the pre-experiment homework.

VERY DIFFICULT!Lots of hours are required.READ the book.Do tons of problems.FLASH CARDS are a must!Go to office hours,he's very helpful if you show an attempt.Lectures are at times hard to follow.Mainly "just read the book, a lot."

Professor Harrison is really nice. Funny guy, sometimes awkward jokes, but yeahm he makes the class fun. Very willing to help during lab. Study for tests!

I took chem 2 in the summer of 2010 and though it was a total breeze but I had seen the material before as well. Funny guy, dry sense of humor and friendly. Like lots of teachers, work hard, think before you speak and he'll do everything in his power to help you out.

Harrison was a hard teacher for me. His tests were very tricky, alot of stuff not covered in class. use office hours! do all the homeowrk and labs because you will need the extra pts to make up for possible very low test grades. He won't spoon feed you the material. But once you pass his class you really feel like you've accomplished something

Yes, Ochem is a difficult class, but the key is to keep up with the material; if you do, it's not that bad. He's a really cool guy so don't be afraid to ask questions, and do the suggested problems because they're really useful. I hated gen chem but I loved these classes because I felt like I was genuinely understanding chemistry for the first time

Just finished his summer '12 class. It was a blast! He's a very genuinely nice guy, and loves getting to know his students! USE THE TEXTBOOK! Do the active examples, and suggested problems, and work over all the ones he does in class. He even posts previous exams online which are almost identical to his exams. Put in effort and you'll do great :)

Ochem is a hard class no matter where you take it. Harrison does everything in his power to help his students pass; 80% for an A, hides extra credit on all exams and finals, extra credit opportunities, will show you mistakes on labs before turning it in, and comes into his office hours early 99% of the time. Take advantage of this teacher.

Harrison is fantastic!! Dreaded chemistry and was upset that I had to take it, but ended up not only doing well, but enjoying this class. It was very hard for me though, you really have to put the work in. He is really friendly, a fair grader, humorous, and easily accessible. Use office hours and practice tests. He'll help you with anything.

He's extremely intelligent, which I think makes it hard for him to relay the information effectively to the students. That being said, once you get in a groove and understand his methods, it's relatively simple. Also, he is ALWAYS willing to help and explain things further in office hours, which people rarely attend, so take advantage!

Took his chem 2 class in the summer. It was pretty difficult because it was shorter than the normal semester. However, it is still manageable and if you put the time in you will pass! He's a really great guy and kind of funny. Needs to learn to draw.

Anyone complaining about his lectures is probably just not listening. Anyone complaining about his tests probably just doesn't know the material as well as they've told themselves they do. Anyone complaining about the homework (all 3 pages of it per semester) has probably already dropped. He is fair, great at lecturing, and beyond helpful.

Harrison knows o-chem in and out and has very high expectations (& very little tolerance of BS answers). Tests are about your ability to apply what you know, not regurgitation, and are graded ungenerously. But: great sense of humor & travel stories, helpful in office hours. You'll work harder than you ever have and learn a lot. 80% and up is an A.

The class is tough but he gives study guide. Follow it and you'll pass the class. 10 online hw and 12 lab work which is not bad. He's grading is great since you can pass the class with C.

Do yourself a favor and take this course. Organic chemistry changed the way I study. Every other class is a walk in the park after this class. Biochemistry at UCSD is easy compared to this course. Dr. Harrison also helped me get an internship over the summer. Don't be lazy and work for it! Especially you pre-meds who want it easy as undergrads.

I'm almost done taking his chem30a class and it's hard. But in 29. I'm not there to good around. I came to learn and be taught by the best and Mr. Harrison is not on a master at chem but I pretty funny guy. He is a though teacher , but I want the smartest there is and I have to show him respect. Thank you Mr. Harrison!

He didn't talk about Gandalf!!!

Harrison is one of the best chem teachers I've had. It's a hard class, but it's ochem for crying out loud. I found that many people weren't willing to put in the work to succeed. Yes, Harrison is difficult, yes he is a tough grader, but he is a teacher who is always available and willing to help (ONLY if he sees you are putting in the effort).

Harrison doesn't baby his students. He treats you like a college student. If you're not willing to work, you'll fail. There is no extra credit and or 2nd chances but I appreciate it. He is a caring teacher despite what others have said and has explained things to me a million times over. Show him you care, and he'll show you he cares.

I personally thought Mr. H was a great teacher. He cares about his students, and because of this he puts you through hell. He is difficult and expects a lot but explains things very well. I enjoyed the class a lot. It really rewards your work efforts. I've learned more here than I could have at any UC or CC. He prepares you for Upper division well.

He is a fair(but tough)grader & expects a lot from students. I don't regret taking his class. I know more about ochem than any of my buddies at UC's. He teaches you all you need to know about ochem. I knew it inside & out by the end, well enough to tutor it. Great teacher, lots of work, awesome subject. Ochem is how everything works.

Tough class, but it is possible to do well. He tests your UNDERSTANDING of the material, so don't think you can everything and think you'll be fine. It's all about comprehending the material and being able to apply what you've learned. His exam problems may not be what he went over explicitly in class, but he gives you what you need to solve them

Be prepared to work in this class. Do every suggested HW problem 2x, always ask questions if you dont understand the topics. This isn't your typical community college like a sociology class, this is a Organic Chemistry class that is preparing you towards for graduate school. Attend class everyday otherwise you will be lost when you come back.

Chemistry isn't easy but Harrison does a reasonable job explaining each concept. He isn't the best at answering students questions but he reviews the material at the beginning of every class. He's a tough grader with the labs and expects you to do them right. Exams are long but not too difficult. Will give points for doing most of the work correct

AMAZING professor for ochem. It's a hard class but he is very accessible, helpful and does his best to ensure people do well. 80% is an A, so I have seen lots of people go from failing to an A. Be prepared to study but he is as good of a professor you're going to get for ochem.

Harrison is always accessible outside of class. I went to office hours every day and used his second lab section as more office hours. Willing to walk you through concepts from start to finish 1 on 1. Grading is very specific but he will go over every assignment with you before you turn it in. Tests are hard! Need to be willing to ask for help.

Honestly, he was such a nice guy. Super supportive. He knows the class and material is super difficult and is willing to help u anytime. He is very accessible always very early to his office hours. he even gave pep talks before the exams. His exams are quite difficult but he has many practice problems that are similar.

Harrison is a good professor, he's very patient with students and though he is a tough grader if you ask him questions on homework or labs he will answer them and help you the best he can. You will need to take out more time to study for this class than most but it should be expected with a high level course.

Tells hilarious stories in lectures and is good at teaching the material. The way he grades labs is bs though.

I don't unf

I don't understand the negative reviews. This professor is so sweet and very funny.. good with puns also. He's one of the nicer professors I've had. It's a tough class, but it's supposed to be. He made it very enjoyable.

The review below surprised me. I found this professor caring, approachable, and never condescending. As an introvert, I still felt comfortable with him. He's a tough but fair grader. If you study, you'll do well. I spent only weekend before exam studying and got solid test scores. He's funny and makes class enjoyable. Super chill guy!
