This is probably one of the hardest classes I've ever taken. He is always late, he acts like everyone knows or expects everyone to know exactly what he's talking about. He goes through lecture really quick and goes through calculations rather quick so it's really hard to follow sometimes. He gives out 4 tests 1 is take home and he drops 1 test as well.

this class is hard but you need to study. the study guide is exactly the same as the exam. you read the book, go over your notes, ask questions and review the study guide then you're fine.

Shouldnt be allowed to lecture, terrible. Beyond boring, explains life story of theory inventors, and rushes through the actual theory's you need. 15mns late EVERY class, expects you to stay 5-mins late. Everything said is so drawn out. Gives practice pre-tests that are almost same as tests. Don't take if you want a real understanding. Need Txtbk

He gives out pretests and study guides before every exam if you know what is on those youll do fine. Take notes in his class but use them as an aid because what he spends a majority lecturing in class will not be a predominant on the test. Oh and I don"t think he has ever been on time.

First ill start off by saying Dr. Alexander is a nice guy, however he is the worst teacher i have ever had in my whole life!!! I am an honors student, I strive for success in every course and I received a C in Dr. Alexander's course. 99.7% of what he lectures in class is not on the test! His pretests are not a good representation of actual tests!!!

Probably the worst professor I've had. His lectures are extremely boring and he focuses on one not-so-important part of a lesson and explains it in a painstakingly difficult-to-follow manner. Our class is 3 weeks behind schedule from the syllabus. You're better off reading the book and learning from that on your own.

If you want to learn Chemistry please DO NOT take him! He is unorganized,late to every class! He doesn't explain clear you basically have to learn chemistry on your own especially last week before finals he gave as to learn on our own four chapters... He didn't even explained them. I am so disappointed and frustrated because it's not an easy class already. We were four chapters behind and the lab that I took was ahead so go figure yourself what the lab is about...

if you like having no mandatory hw and just tests like me then prof A is awesome (the hw is EC and just helpful for studying) I didnt waste any time doing excessive amount of hw in his class, once i understood the material then i could go do other things.Just do practice tests cause thats 90 % of whats on the test. theres a few q's that are random

hes a nice guy, alot were able to crash the class so im extremely thankful. his teaching is ok, there was construction near the class so it was hard to hear him since hes not very loud.just sit up front. there was no HW and the attenedence wasnt strict. Just study on your own cuz chem is a hard topic for anyone. Easy class to pass, hard to get an A

Alexander is very nice and incredibly smart. But he is not a teacher. He showed up 10-15 min late for every single class. We got behind the schedule so we had 2 exams in 3 months, and the last 2 exams and the final in a month and a half. He "reviewed" chapters in his lab not covered in lecture because he got behind and if you could't go, tough.

i agree this class is difficult. all chemistry is. i had him for my 3rd and final attempt to pass for my nursing. I really put in effort that he could see. alot of extra credit, staying after as much as he had time, and stressing to him about how bad i needed to pass! I know i failed the class but he passed me with a C and told me i earned it! :)

Prof. Alexander gives a lot of opportunities to study by handing out pretests and practice tests. However, you should read the chapter on your own and try to do all the red questions. Then you can get an A. The tests aren't that hard but the calculations may take very long. He's ok for chemistry.

AVOID HIM! Sweetest man ever, but horrible teacher. NEVER returns you homework, labs, etc. Makes up grades. disorganized. ALWAYS 20-40 minutes late!! Poor and boring explanations.

He is a very sweet, funny guy just not that great of a teacher at all. He was always off track and we were always behind. don't take him if you don't have to, if he is your last resort, I would say the textbook is your best friend. READ READ READ ALOT and DO ALL THE HOMEWORK PROBLEMS with a good tutor. no social life and no help from him.

Do not take this class if you really do want or need to learn Chemistry! Was intimidated to ever ask questions or seek help after class Made me feel stupid or like I was bothering him. Even though it was obvious the class was lost, he would just keep going. Explained everything in the most difficult ways Not enough practice work Fair grading

This class requires your full dedication and effort. Read the book and practice the pretests. 87%+ is an A, 75% is the cut off for a B. Dr. Alexander will give you the grade you EARNED. He allowed many students to turn in late assignments and take tests late, just talk to him and he will help you. Sit in front b/c he is soft spoken.

Dr. Alexander is an extremely nice person. Ask any questions you need he will stop the lecture and answer them. I had him for both chem 100 and 130. Exams are EXACTLY like the pre-tests just study those. I barely used the textbook. Def crammed lots of info in at the end of the semester. For organic chem class it's a breeze. Don't be intimidated!

Honestly WORST professor I've ever had. He's not a bad guy that tries to screw you up, but he's definitely not a teacher either. Lectures are boring and he does NOT know how to teach. Be ready to teach yourself chemistry. He's always late for class at least 5-10 minutes and sometimes 15 but you still need to wait for him -.-

When reviewing he will not take it upon himself to explain ?'s but will stand until until someone asks. AVOID AT ALL COSTS!

The course wasn't hard, it just required A LOT of studying. He does not assign homework, but you must definitely read the textbook before class or you WILL feel lost. Do the practice problems in the chapters, see him during office hours. He is friendly, very approachable, and willing to help. Definitely do the PreExams, it will help!

I do NOT recommend taking Dr Alexander for Chem and I'm good @ chem. Does not know how to teach, lectures are unclear and disorganized leaving you struggling to learn and understand concepts on your own. Lab is a nightmare, makes you do a lab manual and if its not EXACTLY what he wants, such as the photocopy being too light will take off points.

Dr. Alexander is a nice guy, don't get me wrong, however; he ranks as the worst instructor I have ever had so far at any school. He does not explain anything clearly at all. If you take his class you will most definitely be teaching yourself. Mesa needs an Ochem teacher that actually cares about his/her students learning the material.

Dr. Alexander is the worst professor I have ever had. He starts lecture 20 minutes after the designated time, consquently throwing him behind schedule. The class will be a month behind in lecture. He then scrambles to catch up rushing through material the last few weeks. He is extremely disorganized. Be prepared to teach yourself in this class.

Teaching may not be the best and can be quite confusing. Nevertheless, his exams are close to his pre-exams(opposite questions in actual exam). The key is to make a study group, basing all your time in studying the pre-exams inside/out. Exams are all multiple choice. Class outline: Four exams(drops lowest), essay, and final. Curves grading scale!

Do not take the class if you're unable to learn by yourself or put in the time. Definitely do the pre tests and understand the problems in the pre test. He is very patient and approachable. Do the practice problems in the book, read the book, and make sure he knows who you are because he does curve!

Just study the Pre-Exams. I didn't lose too much sleep over this class. Get an A on the research paper to boost your grade, which I didn't think he grades too hard on. You can drop 1 exam out of 4. The cumulative final was pretty hard though. If I can, pass you can pass.... unless you really just put no effort at all.
