He is hard, but he makes his class fun after all... (Dr Price is better though...

Mr. Armstrong is quite the character, he is very energetic at all times no matter how early it is in the morning. He definitely won't bore you, and he provides some very useful analogies. His handwriting is clear, and so is his speech. I find him a very good chemistry teacher. His exams may be tough, but they're the same ones that Dr. Price giv

Good teacher and funny. Extremely clear and sharp in explaination. Although not particularly flexible and his grading is strictly "by the book", yet chem IS a tough course. Unless a "natural" expect to work very hard for a C or B. What you put in is what you get out and Armstrong will make sure you have the tools to get you where you are heading.

The class he teaches chem 101A requires a fair bit of attention (read insane amount of work). However, Mr. Armstrong does a good job of presenting material. He knows his subject very well and is interesting to listen to. As far as I can tell, he's more than willing to answer any questions you may have. Well, unless you're lsomeone who waits till 5 minutes before the homework is due to ask a question.

High-energy, smart, entertaining and informative lecturer, *lots* of example problems in class. This was the hardest course I ever had, but I enjoyed it. Homework sets are harder than the text's, tests are very hard and too long to finish unless you know the material VERY well. Take Chem C with 101A - smaller class, more problem-solving practice.

Great Professor! Very energenit, you will never get bored. he pairs you with another student in his class unlike the other professor. he only gives 2 exams, easy ones too. Take him, you won't regret it.

Dr. Armstrong is extremely helpful...he can make you visualize everything... he uses a lot of example... I think his explanation is the best base on my experience... he is the second teacher that I took for Chem 101A.. and he is the best!!!

Friendly, enthusiastic, encouraging. The material is challenging but his lectures are straightforward and he's willing to answer questions. Mandatory weekly homework, but it helps you understand the material a lot. Quizzes/tests aren't easy, but managable if you do the work. His grading scale is felxible b/c the class is hard. Very good prof.

Excellent professor! I think people are just angry b/c it's a hard class, but that's how things are at a 4 year school.I appreciated his class after having classes at least 2X as hard as his class. Just hang in there and study harder than you're used to. If you go on into a science based major, the classes get much much harder, it's a good intro.

He's one of the best instructors CCSF has. He maybe touch and strict, but his presentation is crytally clear. Mr. Armstrong is extremely helpful to his students, especially those who are eager to learn. He is NOT mean at all, not by any sense, it's just his professional style. He gave good advice to me when I was accidentally dropped from his class

Loves to teach and teach Chemistry. Wrote the book City College uses. Not a PhD, but is better at explaining the subject than any PhD I have met

Great instructor. If you are willing to put the time in to study and do the homework regularly, you'll succeed.

The BEST teacher ever! Don't be intimidated. If you want to learn, take him. He truly knows what he is talking about and makes Chemistry interesting. He is a very goofy guy too. No boring moments in class. I have learned so much from him but you really need to stay on top of it. Read his book EVERYDAY, understand it, and do the homework.

Take this class from this man if knowledge in this subject is what you want. He da man. Hardest class I ever took, but you know, Chemistry is worth knowing to to get through life. WARNING !!! If you are a sissy or a loser just trying to squeak through life&school this class is not for you. Impossible to cheat on his tests.

I know this is City College, so this guy is not what most people expect in an entry level Chem class. I have a prior university degree so I've taken many classes-- if you are in school to be serious this is one of the best professors you can have. He gives you a dose of the real world-- small mistakes in science are just as wrong as big ones.

Dr. Armstrong is a very smart person. He knows exactly what he is talking and he explains everything in details. However, he does have favors in student. But if you work hard, he knows it. He is a good lab instructor.

Armstrong is the clearest teacher I've had at city college. All of the comments I've read about him are untrue or extremely exaggerated by angry students who couldn't get the grade they wanted. I didn't need to read the book and only studied off his lectures and its enough to do the hw and tests. Other students rate him bad due to the subject.

I was hesitant to add because of previous comments but his lectures are clear, interesting, and sometimes entertaining. He's a nice guy and he grades exams fairly, but they are HARD. In lab, he's very helpful unless its something that you should already know.

There seems to be several sour-grape student reviews about Prof.Armstrong, and the CHEM101A course.... I thought I'd throw in my opinion.... ...One telling comment by a reviewer was that he/she reviewed the material for 3-5 days before an exam, and only managed to get a C grade.....That's typical of students who have taken many classes each semeste

CHEM101A is supertough. Stop whining, and get on with it. Prof. Armstrong would have become a vet if he wanted everybody to like him...His job is to get you up to the standard required for moving on to even tougher courses - And he does that extremely well.Give yourself the necessary 25 hours per week study time, and you'll agree. Make the effort!!

I did not share the same experience as most of the reviewers here have. He is not difficult. I went to class all semester long, but did not own or look at the textbook and got a B overall. He is very helpful; if you ask him a -good- question, he will respond with utmost interest. Taking Su now for 101B and I wish Armstrong taught this instead.

His lectures were greatly organized and I appreciate him for that. However, being that he wrote the textbook, his tests did not reflect what we learned! Weekly quizzes and study guide did not mimic the content of the tests and I swear, don't think grad students would understand either! This class is A LOT of work.

I took him for lab, and he was really helpful. He explains chemistry really well (sometimes with great analogy) and answers your questions thoroughly. He is always there during office hours. His lab quizzes were not something new, just go over your lab notebook before the quizzes and make sure you understand the concepts, and you will be fine!

He is extremely clear and understandable. He dumbs chemistry downs for beginners. He wrote the chemistry book that chem 32 uses so he knows what he is teaching. He hates when people are late, so don't be late because he feels distracted.

The insults to Mr. Armstrong are from students who don't want to do the work of learning chemistry. It isn't his fault that the subject is difficult. He is a great teacher with high expectations.

He explains well whenever it is related to calculation. It is kind of confusing when he talks about orbital structure though the topic is hard to explain in lecture. After all he is good and nice.

I had a lab with him, and it was a piece of cake. Don't get me wrong, he's very strict on attendance and checks the pre-lab each time, and if you don't have it he WILL send you home. But other than his strictness he's very pleasant, helpful and clear on the subject. He's extremely available to answer all your questions even after the semester has e

Great professor. I actually switched mid-semester to take his 8 a.m. class. He loves the subject and he really loves his students. I worked my ass off for an A and any one else who got an A will tell you the same. TAKE FOR LAB! Phenomenal lab prof. He doesn't put up with dumb/rude people. I always thought his grading was fair.

Possibly the best teacher on campus.

This guy is an inspiration for me. He's what a great teacher is. He makes chemistry interesting and easy to learn. However, on his tests, he makes you think a lot more than the "plug into the equation and you get A grade" type of tests. Take him or Glenn for lecture, and Stuart, Hurt, or Wong for lab. Online HW, 75-85% qualifies as an A in class.

Chem 101A is a difficult class, and this teacher's tests are impossible! I think he does his best, though. He introduces his students to many resources for help, and he's very lively during his lectures. If you're good at chemistry, you'll enjoy this class, but if not...I worked so hard, but I still had a D, so I withdrew and changed my major.

Clear & Straight-to-the-point and Animated in LECTURE. No Procedure write-ups in LAB needed. Just be able to follow instructions and you'll be fine. Open to all questions--just be precise in asking what you don't understand or why you don't understand something. Fair in grading. Understanding to personal concerns, just LET HIM KNOW. Fun character!

Without a doubt one the best professors I have had. Professor Armstrong provides clear, concise, and entertaining lectures. He is understanding, wants students to succeed, and truly motivates students to try their best. But my favorite thing about him is how funny he is. Honestly I was laughing half the time in lecture.

one of the coolest, professional, and understanding professors at city college. A+++ professor. Thanks for everything, Dr. Armstrong, and best of luck to all of his future students! =))

Chem 101A is the most difficult of all courses at CCSF. Mr. Armstrong's class is designed to make sure that you are able to go on to any other Chemistry class in the country, even Harvard. It's that tough. That said, Mr. Armstrong is a great instructor. He is very helpful, and if you really want to get some one-on-one time with him, take Chem C.

Chemistry is an overall difficult subject to some, but Armstrong explains concepts really well. He is very knowledgeable in this field; he even wrote the textbook. There will be homework every class session and quizzes every week, but this overall helps you with the class. If you need help, just ask the man.

Thank you Dr. Armstrong!!! Best chemistry professor at CCSF! I have learned so much and greatly appreciated his teaching style and dedication to his students.

Best chem teacher ever!

Mr. Armstrong is one of the best teachers ever! He is strict about his assignments and grading, but he makes his class lectures really fun. Chemistry is hard in general, so be sure to buy his book and read it and study. He knows how to teach and he's good at it. Highly recommended!

one of my best teacher.His lecture is very clear and concise.If you work hard, you can get good grades.

Attend the first day of class and lab meetings! Keep up with the lectures, which are straight forward. Need textbook; be ready to commit to at least 2hrs of homework that will prepare you for tests and quizzes.

have background knowledge in chemistry; otherwise you may have hard time learning new concepts and unfamiliar structures and vocabulary. test are based on application of concepts from textbook; lectures summarize key points. devil in the details! prof is from harvard, can seem condesending sometimes but his explainations are concise. +2 hr study!

The best teacher I ever had. He is a great teacher. Gives you a lot of homework which is fair and makes class a lot more easier for you. He is very organized. I loved his class. It'll be good for you if you'll take his class.

I remember taking his class a while back during my freshman year at CCSF. I took general chemistry, a 5 hour class (lecture than lab). I remember not doing so well that semester, asked him if I could get a regrade, and he said "no". Mad as a freshman, now, just realized he just wants his students to earn their grades, not suffer. Great person

Ultra clear on material and explained things thoroughly (he did write the textbook). I was rarely confused, which is uncommon for chemistry.

Mr. Armstrong is the best chem teacher I've taken. He's very clear about lab procedures and grading schemes, but he won't be condescending if you try to ask questions. He's very approachable and funny too. However, you'll have to do a lot of work. Chem Lab requires both in-class and out-of-class work but it's worth it.

He seems to care about his student's success, but you got to put in the effort. There is hw every class, quizzes every other week and 3 exams plus a final. This class is very time consuming. Be prepared to read the entire textbook because not everything in hw, quizzes and exams are covered in lecture.

I do not like chemistry but Armstrong is great and an outstanding professor. Chem is boring to me but I was only good because of his energy and he knows how to teach. Chem 32 do all the homework and you will pass the quiz and exams. Don't look up HW answers until you've done them. I regret not doing it in the beginning of the semester.

It is a lab section! He gives explanations before experiments, so you will know what to do and finish the lab earlier. You just need to follow his requirements in order to get credit for the lab notebook. Remember to show all the calculations and record all results into your notebook to get full credit.

1 mini quiz, 3 lab exams (open lab notebook). Exams are ok to easy as long as your notebook is neat with info you can find easily. Expects you to work for your grade. Extremely helpful if you ask questions, but if you ask something you should already know, he won't go easy on you. He's sounds passionate in chemistry. Recommend for lab.

Cheerful, approachable, patient and happy to help. I was anxious about Chem Lab because I have essentially no background in chemistry but Armstrong made me feel comfortable to ask questions which was a huge help. Strict in some respects but a very nice guy. Always wears adorable science teacher outfits. The "book" is a free lab manual they hand out

Responsible,parient teacher. If u really want to learn and improve, take his class. You will absolutely feel that your tuition fee is very worthful.

Hardest class I've ever taken in my life, and I've taken some tough ones. Despite the challenges this class presents, Mr. Armstrong is a really good teacher. Very friendly and encouraging but definitely a tough grader. The class itself seems like it could use some restructuring, as the avg. grade on most tests was around 55%. Prepare to study hard!

The best professor I've had at CCSF. Clear, organized, approachable and competent, his lectures line up perfectly with the text (which he wrote) which feed directly into the quizzes that line up with the exams. No surprises, good pace, well thought out. There is homework due every day, but if you do it you'll do well. Highly recommended.

Chemistry is a difficult subject, but Prof. Armstrong makes it easy to understand. It is up to YOU to study and learn the material! I worked my butt off and got an A in the class but only because I tried my best. He is very enthusiastic and only wants you to do well. Take this class seriously and you will do fine!

Great teacher but be sure to work for your grade. Grading is based on hw, lab, lec quizzes, exams and on time quizzes. Plenty of extra credit opportunities on the on time quizzes. Hw can be long and challenging at times but prepares you to do well on quizzes and exams. Genuinely cares for his students and willing to help outside of class.

Super challenging and meticulous Professor. Still, he's passionate about the subject and generally more than willing to help you out during officers hours. Also cares about his students and has fun with his lectures. The class is very hard though and requires a lot of time devoted outside of class time towards homework and studying

Armstrong is among the best professors I've ever had. He won't mention it, but the guy graduated from Harvard with a chem degree and is teaching at CCSF! The class is extremely difficult, but he is very upfront about what is expected. I didn't like the on-time quizzes though, they seems very juvenile for a college course. Take him if you can!

Professor Armstrong is easily the best professor I've had in college. He is very passionate and knowledgeable about chemistry. His course is very challenging and he makes you work for a good grade, but you will come out the other end feeling accomplished. Would love to learn more from him!
