Chem 1A is no joke. You need to be serious when you take this course, if not then your grade will suffer. Once you've fallen behind in the course, it's nearly impossible to catch back up. The amount of material covered is intense. Do the readings before lecture. Go to all the lectures. Get a good study group! This is what i did, i recieved an A-.

Do not expect to come out of this class with anything better than a high D/low C, unless you already have a strong background in Chem and no other classes.The class average was 64.2% He does not curve and thinks most of his class gets D's because they are D students.Take this course where the professor isn't going out of his way to give low grades

I didn't think this class was that hard. As long as you take the time to study, (which is a lot of time) then you will do fine in this class. Mack has the same jokes every semester so try to pass it the first time or you will hear it all over again. The trick is to get a good lab instructor. And STUDYYYYY!!

As long as you study, you will pass. If you don't study, you will fail. Simple as that. Every semester he comes up with different ways to teach students about chemistry because this is what he is researching on right now. Same procedure but different ways. Very easy if you study!!!

He's a good teacher and he makes chemistry as entertaining as possible. Besides chemistry isn't that hard anyways. In a nutshell it's just counting. Besides the study guides he gives out before the exams have some of the same questions as the exam. There's no reason you should pass this class.

At first I was impressed by his humor and his stimulating pwrpts. Then over time I realized all his flashiness does is hide the fact that he doesn't really actively teach. Never writes problems out, relies 100% on pwrpt, speaks way too fast. Uses the same test questions from semester to semester. OL HW/Quizzes are difficult. Too much work per week

Don't be fooled by all the negative reviews. People just give bad reviews if they get a bad grade and blame it on the professor. If you are planning to be a Chemistry or Biology major then this class should be a cakewalk for you. If it isn't then you will seriously need to fix your study habits because the classes only get harder after Chem 1A.

Dr. Mack is the funniest professor I've ever taken. I would read the chapter before each lecture and it made the world of a difference because he doesn't lecture on every topic, just the more complicated stuff. He does put textbook material on the exams that he doesn't cover in lecture. Best of luck to everyone in Chem 1A!

Reviews are a bit dramatic. You have to put the work in, he tells you that as well. Several opportunities for extra credit, ppl come into the class unaware of how difficult it will be. Fast pace, go to lecture and get help. Is he the best? No. But very do-able in his class. Do the hw, study, go to lab lecture and discussion. Its one semester w/ him

Dr. Mack is awesome. Really enjoyed his lectures. Reviews here had me expecting the worst, but I found it to be an extremely fair and well-structured course. There IS a lot of work, but it's a 5 unit class with a lab, so it's to be expected. Lots of quizzes and exams but he tells you exactly what will be on them. Overall, this was a great class.

Took it Spring 2022. Mack does assign tons of hw but the extra practice does help a lot with understanding. Bonus credits are provided on exams, all of which are NIEs. As tedious and repetitive as it is, grind through the work and you'll be rewarded with good grades. Get to know the man too, he really isn't as bad as people make it out to be.

The course was introductory chemistry. Any of the bad reviews for this intro course honestly couldn't handle the basic workload. Class was straightforward and the professor is an entertaining guy. A lot of work and dedication is needed for this class. Dont take the class if you are lazy. Get your work ethic straight before you take the course.

Dr. Mack makes chemistry fun. Beware though, its a hard class. You will need to spend the time and effort to get a grade you want. However, Dr. Mack makes lectures fun and some complex topics easy to understand. He is very down to earth and you can get help from him during office hours. He answers emails on a specific schedule though so careful.

Overall a good professor. His lectures are clear and he includes a lot of humor to spice things up. This is a weed out class, so make sure to become acquainted with the subject as there are a lot of people who drop out of the class. Just do your homework, come to lecture, and read out of the book, and you should be fine.

The only way to be successful in this class is to attend every single lecture and discussion, read the material before lectures, keep up with homework and do all the extra credit. I also rewrote my notes and spent 2 hours every other day studying to try to understand the material. However, I still failed and was often intimidated by his attitude.

DO NOT TAKE HIM! Do not let all the good reviews trick you (it tricked me). He has been teaching for centuries he was probably better years ago, but nowadays, he is awful. He does not care about students and has told me personally that he is just ready to retire and complains about still being here. If you want to pass Chem1A, take Rebecca Peebles

Dr. Mack is the greatest professor I've ever had, and he has a good sense of humor. He presents Chemistry in the way that makes it simple, and considering how difficult Chemistry is as a subject, that is an extraordinary feat that not many professors can replicate. Exams are hard, but the homework and quizzes are pretty easy, with extra credit.

Dr. Mack is nitoriously given a poor rating on here however, I think people just do not enjoy chemistry. Dr. Mack is a caring man who wants his students to succeed. His exams are fair. If you get a bad grade, you did not take advantage of the opportunites presented to you not only by Mack, but by Sac state. If you're struggling join a PAL.

Exams are scantron so there's no room for error. Gen Chem should be broken up into 3 semesters. The volume of information thrown at students turns Chem 1A into a weeder class. Dr Mack's one of the best teachers to take. You just have to put the time in. People that give him bad reviews just didn't study outside of class.

Dr. Mack is an amazing professor. Pay attention, attend lectures + discussion, and you will easily pass. If you are struggling, ASK FOR HELP. The people who wrote negative reviews likely did not study outside of class, nor did they attend some classes. Chemistry is not easy, so you need to put in a great amount of effort to get a high grade.

Dr. Mack is a good person.He genuinely wants everyone to pass the class. I somewhat agree that if you didn't pass the class, it's cause you didn't put in the effort. We had weekly quizzes & homework, 3 exams, a final, some lab reports which were difficult because the lab manual was confusing. The class structure is difficult, and he has his quirks.

Had Dr Mack for both lec and lab. He's rad. Go to class, practice homework and ask questions outside of class if you are having trouble (in his office hour or the chem tutor center). Chemistry isn't a subject you can do without putting the time in. You just need to practice outside of class. It's that simple. Dr Mack is the best. Take his class.

Dr. Mack is a funny guy. Just know he hates phones, & he'll tell you to not be afraid to ask questions, but when you ask him he will joke about you in front of the whole class. He also is not good at re-explaining things so you might want to really read the book for this class. Other than that he gives a good amount of extra credit opportunities.

He's chill and will be there for you if you need help understanding something. He's teaching a Chem class with a TON of material to get through. He has a straightforward standard for his students: knowing how to do the chemistry. My only complaint is that exams are on Scantron; no partial credit. I'll never understand how that's okay for Chem.

Dr Mack was an ok professor. He did try to make class fun/interesting. The 3 exams are worth 30%, quizzes 10, final 20, lab final 5, proficiency quizzes 7.5, HW 10, and labs 17.5. No curve but there's always EC if you can solve net ionic equations so I would really try to learn those because that will give you a huge grade boost. EC on HW too.
