This professor does not teach well. He stands in front of a room, reads off a power point presentation that (anyone is capable of doing)and does not allow sufficient time to take notes.

he is soo not helpful and he is very unclear and confusing

Dr. Brack is unclear in his teaching methods. It takes 4 hours to complete an examination. He doesn't teach the material and then expects us to know it.

This guy flat out sucks. He is the worst professor i have ever had the misfortune of having. He should be fired.......this guy is horrible.

Clearly doesn't like teaching. Very unprepared for class. Constant mistakes are very distracting. Comes late and talks fast but doesn't cover very much. Taught 1/10 of the class material in the last 40 min of class. No excuse for this!

He is the worst professor I've ever had-very unorganized- gets confused with what he says, can't teach and taught us half of the final material the last day of class-overall horrible teacher-stay FAR away as possible

Dr Brack is a horrible chemistry teacher. Not only is he extremely boring but he has no idea what he is doing. You might as well teach the class yourself. He is extremely unsure of himself and the test contain information that he never teaches. STAY AWAY

He's incredibly disorganized. He confuses himself during lectures and hesitates a lot. He seems to know the material but cannot articulate it well. He's very insensitive to students. He's unprofessional,absent-minded,condescending, rude, and he gives way too much work for a one credit lab.

Confusing, and not funny.

Butchers science -> I wanted to commit suicide in the class; when writes problems, the boards are messy; doesn't go over HW problems; never learned stuff on tests; unclear; boring (stopped paying attention, others slept); powerpoint=bad lecture; huge curves b/c can't teach; ONLINE quizes to take during MY OWN time? Should teach it myself. STAY AWAY

teaches from powerpoint so he's lazy

Come prepared to class with a full course meal for this professor along with a textbook and a noose. It is too difficult to put this class into words. Basically his test questions are nowhere to be found in the textbook. Rude discouraging and condescending. Whispers as he clicks through the powerpoint presentation and gets extremely angryifudntshow

The worst teacher I have had at Hofstra University. His "classes" are entirely based on PowerPoint presentations prepared by the textbook's publishers. The tests are heavily curved because no one learns anything. The average for most tests was 50%. Avoid this professor unless you enjoy learning everything on your own.

Dr. Brack is the worst professor I've had at Hofstra. He stands at the board and talks to himself, he cannot TEACH for his life. You pay $3500 to teach yourself. Good luck! Let's just say all my test grades were 50's and one 73 and i got a C+, the curve is ridic. Go to him after a test & he wil prob give extra pts ;)

Let's see here...quite possibly the worst experience I've had a Hofstra thus far. Don't even bother worrying about the lectures because the tests have nothing to do with them. He has a good curve, but you will learn nothing is this class. Don't get stuck with him..wait until someone else teaches it!!!

What a WASTE of Time & Money! DO NOT TAKE him for Chem 3A or any other Chem classes. Goes 100mph in class as if you knew this stuff of over 30 years as he did. DO NOT go to the extra credit he offer's. Never gives you the credit for them. Teaches only power point, and very few examples on the board. When he does, again, 1 or 2 problems, that's it.

If you can avoid taking a class with him, do so. He is very unclear about the material he teaches, uses powerpoint slides given to him from the company that makes our textbooks and expects everybody to know exactly what he's talking about when we are all clueless.

THE WORST! AVOID!

You cannot teach a whole chem class with math problem off of PowerPoint and this he exactly what he does sits on a stool in front of class and clicks away very lazy and unhelpful

He is so bad. He taught the class to students who already had taken AP Chem. I did all the homework and still had little idea what was going on. He gives test reviews that are similar to the test, but they only really help with half of the tests. I was studious, but every moment of class and testing was agony. He was awful.

I failed last Spring. Have to take it over this Spring & unfortunately he's the only teacher again!

OWLS sums up how he teaches horrific grading policy exams are literally the online problems but condensed within an hour therefore no one can complete his exams efficiently on time. VERY BAD!!! AVOID

Probably one of the worst professors I've ever had. Attending class is pointless because he teaches off of slides that he has already given you. Quizzes are extremely hard because he has no idea what homework he's assigning (separate website work), so homework will not prepare you for them. Try to get into someone else's class if possible.

As a professor this guy is awful, lectures are all over the place, he's always being corrected by students or correcting himself. Extremely unhelpful too, I had a problem with OWL and he told me to contact the website who then told me to contact my professor! Honestly just do all your homework and the extra credits, the curve is ridiculous

Avoid if you can, that's the best advice that can be given

Don't take him. He's awful

by far the worst professor at hofstra. Cancels class alot, mumbles soooo bad, thinks hes funny but hes not, gives you hard questions youve never done on exams, and does not make himself accessible to students AT ALL.. barely answers emails half the time. Ended up with B+ only because of online questions (OWL). do not take!!!!!!

He's just not meant to teach. He knows his material but terrible at explaining. He makes the material more confusing than it needs to be. Read the book, only way to learn in his class. The way he words exams are confusing and is nothing like the problems he does in class, if he did any at all! Avoid him if you can.

Worst Professor I have ever taken. This professor does not care about the students, only his ego. He practically wants you to fail. I am a good student and had to go to outside help for his Gen Chem 2 class. Unless you are a genius do not take him, you will get nothing from him

Took this class during Summer session at Hofstra. Expected to be fast paced, but Brack makes it boring as hell. His monotone voice is the worst. Our grade was based entirely on our test grades and he did not prepare us for the ACS exam at all. The final was such a shock. The tests were very similar to his class handouts and problems in class.

Class averages are super low because he's not the best at lecturing. It's a self-taught class, basically because of the fact that he will either spend a lot of time on one topic or breeze over an important one. He's super nice, though, but it's a stressful course to try and pass.

Will leave you in the dark about your grade the whole semester with approximations. Nothing he teaches will come close to preparing you for the final. Curve has been said to be historically big, but whether or not it will prepare you for the next chemistry course is really a hard trade off. He obviously knows his stuff, but the class is rushed.

Attending this professor's lectures is useless, you won't learn anything. He shamelessly will mock students about their grades. Don't bother studying for his exams either, he fills them with questions you've never seen before and you won't begin to know how to answer. Visit him during office hours or ask for help? He refuses to help you. Good luck!

Don't bother attending lecture you don't really learn anything. Lost our exams TWICE during the semester and we had to retake them. A lot of material is on each test and he wants you to memorize all the formulas. Do the sapling HW it will boost your grade. Doesn't know how to apply what he is teaching and simply spits material at you. Don't take!!

Is not the best professor the Chemistry department has to offer. He messed up my final grade and I had to email him just to get him to fix it. Does not answer emails that often and you can tell he would rather be anywhere else than teaching chemistry. Rambles a lot in his lectures and you don't really learn much. Is a nice man, horrible professor.

Don't take this class if you can't teach yourself all the material. Lectures are heinously disorganized and he often forgets his point mid-sentence. Learned the same amount attending his classes as I would by not going. The only way I stayed afloat in his class was with outside tutoring. Generous grading scale but it's not really beneficial.

Don't take his class, it's not worth it! Tests are incredibly hard, so there is a huge curve. His lectures are all over the place, so if you end up taking chemistry with this professor, you may have to teach yourself all the material. Avoid him like the plague!

Horrible professor. So many wrong formulas and errors in his quizzes. Also his quiz questions were so unclear. Class was supposed to be online, not asynchronous but he gave us tons of voicethreads at short notice. He was very unorganized and when he did actually lecture during class time we could barely read his writing. He is very boring too.

Lectures were always super unclear, as he would often get off topic and ramble about things that had nothing to do with the class. As others mentioned, he had a generous curve but it was because a majority of the course was not performing well without it. Would not recommend his class at all! Taking his course over Zoom made things even worse.
