Couldn't sit through a single class without falling asleep. Read the book religiously and you can get away with a B. Very scattered style of teaching.....ferris beuler voice.

You pretty much have to teach yourself this class. He doe not have good organization within his lesson. Most importantly he does not know how to communicate the lesson with others.

This guy doesn't know what the hell he's talking about! Clicker questions, Why. Want to know your grade in this class?? Sucks to suck, you'll never know! Why? Because hascall still hasn't master basic algebra... Does he even have a chemistry degree? No but really, I want to see him take his own exam... Got a question for him? Hahaha good joke!

Never puts up grades, so if you wanna know how much you need to get on a test to improve or keep your current grade, you're out of luck. Uses the flipped learning style, meaning you have to watch the pre-lectures and take the quizes on your own time before class. The problem? He's not clear, and you can't stop him to ask questions in a pre-lecture.

He is a terrible teacher. I highly suggest you do not take his class. His final's average is only a 50% that means half his class fails it and the rest of the class doesn't do much better! If your looking to tale a class that you want to repeat this is the class for you but otherwise stay clear. There are better chemistry teachers at NAU.

Very intelligent and nice man. However, I'm not sure why he is a teacher. Least helpful teacher I've ever had and expects you to have a great understanding of chemistry prior to talking the class. He also talks very fast and his handwriting is nearly impossible to read. You have class 3 times a week for 50 minutes, and prelectures for 1 hr a week.

He is a nice man just a horrible teacher who is unclear in lecture and tests are hard. Most people in his class are going through it for the second time.

This man can't explain things for his life. He's brilliant, but doesn't understand that you may have never seen this material before. Don't take his class if you want more than a C.

Great guy and all but awful teacher. Doesnt lecture during class but instead makes online videos attempting to explain the concepts. Homework is awful, he used mindtap this term, one day he would assign 8+ homework assignments that can take hours and the next few days only assign 1-2 homeworks. Good guy and easy to talk to but awful professor.

He is incredibly difficult to learn through and doesn't include much from online homework. In fact he doesn't always have questions on exams that we went over at any point. It is essential to go to class not only to get participation points but to also learn what little he teaches since that's what will be on the exam. I used to love chemistry...

Don't take chemistry 151 with this dude! Boring lectures and way to much online homework. He didn't teach me anything, I had to learn on my own and went to ever SI session. Some how averaged a 68% on all of the exams and still passed with a B. The only way I got a B was because test are only worth 50% of you grade. Worst professor I have ever had.

I always understand my classes so clearly. Not this class. You have to teach yourself literally everything. He will post his old exams as a study guide and only 30% of the questions will actually help you the rest will never be seen. I wouldn't wish this teacher upon my worst enemy. SWITCH CLASSES OR DROP FGS

Dr. Hascall seems like he knows the material he is teaching but doesn't communicate it well to the students. Furthermore he is incredibly rude if you ask him for help. I wouldn't recommend this class unless you like sleeping through boring, monotonous lectures. Do yourself a favor and take Cruickshank.

Take his class if you like teaching everything to yourself. I spent way too much time each week doing online homework for this class, went to SI, attended every lecture, but still managed to bomb half the tests. He isn't helpful even if you go to him one on one. Plus the "old exams" he shows you are nothing like what you actually end up seeing.

I did not think the class was hard, I just wish that he had taken more time to lecture some of the material. He enjoys giving out worksheets instead of teaching specific material. In addition, the homework on Sapling sometimes did not offer much in learning and was just another source of busy work. He seems to be trying his best, but I'm not for it

I took Mr. Hascall last semester. He was not a bad teacher personality wise. Academic wise he was horrible. He would never lecture on things in class. Everything in his class was online. We had pre-lecture quizzes and then given worksheets to work on the rest of class. I had to drop it because I could not grasp the material. DON'T take him

This professor was not the best at making sure that everyone was understanding everything that he was teaching... it was like he just wanted to get out the information instead of making sure that everyone understood what was being taught. I would never take this professor again. He would instead of lecturing would make videos to teach us material.

Honestly one of the worst professors I've ever had. Doesn't lecture in a lecture class. Half the class could fail the exam and he wont bother to curve it. Take any other professor if possible.

If you ask a question he wont answer it, he will simply tell you that you should have done the reading. Lectures were a joke, he didnt teach anything and all we did in class was the online Chem 101 work that would mark you wrong for every little mistake. I am good at science yet I can truthfully say that he was the worst teacher Ive had

Professor Hascall is the furthest thing from a professor Ive had in all of college. While strictly relying on the internet to teach his students, all Hascall does is assign online homework and scoffs at you when you ask questions in class. Dude is a world class goof that talks in monotone and only cares about chemicals (hes part of the corrupt).

Dr. Hascall was the worst professor I have ever had. He expects freshmen level students to simply "teach themselves" by reading a textbook and coming to class each day to have quizzes over it. He does not lecture. If you are a visual learner or need examples do not take his class. He doesn't care about his students. He even lost one of my exams.

Never take this prof. ALL THE WORK IS ONLINE AND YOU JUST TEACH YOURSELF. You come to class and do practice problems. He talks about it before you do them, then the whole time you're doing them, then talks about them when you finish. What could've taken 10 minutes takes a least 45. He's extremely long winded and coming to class feels like a waste.

Dont take this class . Its all online the teacher expects you to come in the first day as a chemistry expert... he doesnt teach

Hascall is absolutely the worst teacher I have ever had in my entire schooling experience. He does not teach any of the material and expects you to have mastered it by the time you come to class. It is very difficult to grasp any of the material, and the fast pacing means it is very difficult to fall behind. Take anybody else instead.

Dont like this professor, missed an assignment and he was no help at all. If you ever miss an assignment or quiz, theres no chance you'll be able to make it up. His test questions are harder than other professors at nau in chm 151. I recommend changing professors.

WORST professor I have ever taken. Super not helpful with understanding the materials. You have to do the assignments before class and teach them to yourself and then go to class and get quizzed on them. I struggle a lot with chem and he made it 1000 times worse. Definitely go with a different professor.

By far one of the worst professors I've had and he doesn't really help you understand the material you just have to take notes before class and pretty much have to teach yourself the content. Not very friendly and doesn't really care.

The absolute worst professor I have ever had. He cannot teach for the life of him and he doesn't care. The average was 62.2 for a test and he said oh well! When the tests are worth 56% of our grade. You read for hw and rush to finish and class is so many chem 101 problems everyone is just trying to keep up with him, not actually learning.

hard tests, doesnt teach

I took the class twice. First time I failed on my own accord. I was very done with the class and didnt want to deal with it anymore. However, I thought it was easy so I retook it with Hascall. I had an A up until the final exam and then dropped to a C because he had refrained from putting months of homework/quizzes in. I had no idea.

He is easily the worst teacher Ive ever had. He doesnt lecture during lectures. He just assigns you a bunch of practice problems on Chem101. The format for the exams is also awful- whats the point of memorizing elements if youre going to use made-up elements on the exam? Do yourself a favor and take any other professor.

Doesn't accept late work and for COVID assigned homework on like four different sites, and only updated the grade book at midterms. Incredibly hard and inflexible.

Overall a really bad teacher. Only assigned chem 101 work during class and never actually lectured. Doesnt give any extra credit assignments or quizzes like most of the other chemistry teachers. Your main overall grade depends on three exams and there is no make up or redo. Didn't learn anything in the class to help for these exams.

if you can teach yourself chemistry youll be fine. otherwise, itll be a hard class. he expects you take notes and use online homework to teach yourself and then come to class to practice rather than learn. -side note- i found his voice irritating and he constantly talked the entire class.

Although I did like his method of teaching this course, it was very heavy on the homework. What upset me the most about this course was that he continued lecturing and giving us work on reading week instead of helping us study for the final. Overall it was very material heavy and you kind of have to teach yourself everything.

I want to clarify that this is not personal but more as a caution. This class is taught poorly in my opinion with little in-depth explanation/ poor answers to questions. The exams make up basically your entire grade (over 50%) and the study material to be very misleading. I would not suggest this professor unless you are ok teaching yourself.

No lecture during class, only brief overviews. Prepare to learn this material via online textbook on your own. Exams make up most of your grade. Lectures consist of doing problems on activchem and code given everyday for attendance so make sure you show up. VERY frustrating and mentally draining.

Doesn't give extra credit, doesn't explain topics that well and answers questions by just restating what he had just said without explaining more. Do not take his class if you are a slower note taker as he does not wait and talks fast.

Do. Not. Take. Him. I was given this professor after my first professor (Rellaford) left to have her baby. He rushed through the slides and skips the examples. Instead of explaining how to solve the problems, he rushed through them with no explanation. Take Rellaford instead she is way better.

DO. NOT. TAKE. HIM. The TA was the only clear one in that class. He says so little in so many words. You learn outside of class and are given very little supplementation in class. The tests are stupidly hard(especially exam 3) and if you don't already naturally understand the topic, don't expect over a D on a test.

Very homework heavy and is horrible at explaining concepts.

He is not a good explainer and makes chemistry even more difficult than it already is. He was a sub in for my class and he messed up the flow of the lecture and class overall. He would go over lectures and would never make sense even when asked questions. He has no empathy for students who are struggling. If you have him, good luck.

I did not like this class. Extremely difficult for a level 100 class. Way too much homework. We learned on our own at home, and he expected us to come to class knowing everything. I once emailed him with a question and he gave me an answer that did not help at all and was not what I had asked for. He did not care when the exam average was 62.

I put in hours of studying for this class and pulled multiple all nighters in preparation for tests and the highest score I received on one was an 80. Multiple people that I know failed this course. Hours of reading and note taking. Nothing is taught in the lectures. If you do not understand one concept, you are lost for the rest of the semester.

The class average for the first exam was 58% and he said he wasn't sure why

HE DOESN'T TEACH!!!!! If I wanted to teach myself everything, I would've taken this course ONLINE. After the first exam this man said "The average was a 60%. I'm not sure why it's that low..." LIKE I WONDER WHY??????

DO NOT take his class. This man does not know how to teach Chm 151. I had an institutional excuse because I lost a family member, and this man did not give a single crap. I have never withdrawn from a class before; this man broke that streak. If you are already locked to this course, good luck. Read everything, take notes on everything, and STUDY.

Never take this professor. If you have him, get out while you still can. Attendance is mandatory but you don't even learn in the lectures. Most notes will come from outside sources and the pre-lecture work. The prof does not care for struggling students, and is quite rude. Waste of time and money.

made a girl cry in class.

He is horrible at teaching to the point where he doesn't even try. We only learn anything new from the textbook, and while attendance is mandatory, its not helpful at all because all we do are practice questions by ourselves. Also, do you study a lot for tests? Doesn't matter. It's not uncommon for him to be straight up wrong. Fire him genuinely.

While attendance is mandatory, this class is basically self-taught. All of his lectures are reviews of things already learned in the textbook. Use the guided notes available in Canvas for pre-lecture videos. In my experience, if you ask questions, he'll talk down on you and make you feel stupid, so it's better to just figure things out yourself.

Worst professor ever! Nothing is organized, he uses like 3 different websites for assignments, none of which are linked to canvas so keeping track of things is a nightmare. Grades HEAVILY on participation it feels like I'm in kindergarten and he speaks in a very condescending tone. He's also terrible at explaining things.

just don't

This class is impressively difficult. The lectures do not help, yet are mandatory. Class grade is bet upon your performance on 4 exams, which good grades don't come easy on. Avoid this chemistry professor. Arrogant, belittling, and rude, made a student cry when she asked a question.

3 practice tests adding up to 195 total questions, and yet there were still things on the final exam I hadn't seen before.

Hascall was genuinely the worst professor and human I have ever encountered. He is extremely unhelpful. The whole class is self taught because he does not teach. He made a girl cry in my lecture when she asked a question about a confusing topic and is extremely condescending. TA's are helpful but he is worst do not take him if u have the chance.
