Yes he's tough, but he is extremely knowledgeable. If you have the time to put in (i.e., you don't have a life) you can learn a tremendous amount from this professor.

Very hard class but a very good teacher. Don't even think about skipping class. For people who think his classes are too hard, maybe you should look in to a different major. Computer science is supposed to be hard

Lorentz is one of the best professors I have ever had. He explains complex concepts incredibly well. His grading is tough, but fair. He is what a college professor should be, and for this reason students that are used to coasting by without understanding anything dislike him.

He is a very good teacher. He is very good at explaining material. Many of his students are stupid and lazy, and since he is fairly strict grader, he has a bad reputation amongst some. You can't get away with BS on tests and assignments, cause he is very smart and knows if you understand or not.

Gave a lot of homework especialy since grad class. Took him cause other section full, but heard he was easier and did less topics so now I'm happy.

Impressive teaching. I got a lot out of the class. I think I was in the top five students, so I was surprized to get a B. I believe I misinterpretted some of the exam problems. But I was very pleased overall, and highly recommend Lorentz for regular expressions.

Excellent class! The teacher is great, and makes us work hard, but at the end we feel that we have accomplished something. I learned a lot in this class, and I wish all the teachers are this well prepared and highly involved in student’s performance.

Come if you want to work you a... off and kill yourself during test

Outstanding teacher, outstanding class! A lot of work, but in the end you feel that you have realized something. Every bit of information in class is usefull and interesting.

Best class I ever had, so far.

excellent professor!! knows his stuff and is extremely intelligent. very helpful, but a strict grader. you will learn a lot after taking a class with him, but be prepared to put in a lot of effort. comp sci is not supposed to be easy!!

Though class. Challenging, but interesting and often humorous.

His grading is unfair as just 25% of his students received an average of 50%-60% of total grades. He is very nice and approachable professor but with his grading and ridiculous exams and projects makes your life like hell. The movie ?Misery? is nothing compare to the feeling you will have during and after the semester.

For Comp-Sci majors, take him for Comp296FCS/FCL as an alternate for Math 326. He's a great teacher and really knows his stuff. He is a very strict grader on the homework and tests though. However he grades on a curve and moves at the class' pace. I learned a lot from this guy than I ever did from the Math 326 professors, so take him.

good professor.really helped you out when you were stuck with a problem. teaches highers concepts than the book and seems like he really enjoys teaching. also you can joke around in the class or throw out ideas and he is ok about it.

Gives really good lectures that you will understand. Doesn't mind being asked question during lecture or the occasional funny comment. Really easy to get along with. His program work however is on a higher level of difficulty then all the other professors who teach 182.

This is a grad level theory course, so don't expect it to be easy. Expect to be bombarded with the most abstract theoretical concepts imaginable. The material was fascinating and he is a very nice man with great lectures. Homework is extremely hard & graded harshly (avg about 50%). One midterm, one final, both VERY hard. I barely made it out alive.

Helpful teacher but semi-hard quiz, hard exam. The only thing that helped me is forming a study group otherwise I wouldn't get the grade ('B') I got. Study group helped ALOT. If you miss a day of class, you will fall behind! Professor wants you to do things his way, hence why attendant is important. Quiz is announced couple of days early.

This was the most difficult class I have ever taken. The assignments will run you approximately 25-30 hours of your time, and then some. It's very rigorous and Lorentz is very specific about points. He will dock you heavily for minor mistakes. The final made me lose my love for knowledge. Don't fret though, because DAT CURVE DOE.

First off let me say that he teaches on a different level than the other professors. He is a very harsh grader and will dock you down if you do not do things his way. The book, IMO, was total trash so make sure you check the ratings first! He was always there in offices hours and did help out quite a bit, but makes you think about the answer.STUDY!

I did not pass this class because of my own study habits. This professor is extremely helpful. Always there during office hours. Has review sessions on his own time. Gets us to think about the problems. He is extremely patient. But, he grades harshly, takes of points for things not his way. Book was garbage.

This class is hard solely on his grading. You can have the right answer but if the proof doesn't make sense to him, you'll get a 0. He's really picky on how he want things done so you have to show up and pay attention. He's the only one teaching this course and there no alternative. If you want to move on, you got to get through him.

If your the type of person who loves to explain every step your doing in words then this professor is for you. If your not then you have to adapt to his way of proving your answer because he heavily grade on that. This class require alot of time doing the homework then explaining the work to get full points. This is fine if its a 300-600 lvl course

If you are a computer science major you need to get a C- to pass this class, but its not easy task, the material is hard and the way he teaches it can be hard for some people. this is not a 200 level course it feels like a 400. Make sure you understand HW and make a group to study with, that helps alot,big curve that helps.

Programing assignment hurt, but hes good with partial credit. Hes always in good mood, and is available if you need help. His class is harder than it needs to be, but really any COMP majors should be fine. I got b when I thought I would fail. Get older edition book , you need it. Exams are straight forward if you go to class. Good teacher.

Great atmosphere in lecture but hardest material ever. Explains topics clearly, makes tough theory easy to understand, but application left to the student, and no mistakes forgiven. Most fail by raw score, but are saved by curve. Each HW takes ~30hrs, not exaggerating, plan accordingly. Anyone can get a good grade, but it takes serious hard work.

Absolutely must attend class in order to absorb content. Low homework scores are normal and exams are difficult - his intent is fair since it is to teach material and therefore some questions are meant to be incredibly difficult. But he tends to curve the grade accordingly. To do well late in course, you must stick to proof by induction method.

Difficult class. It's one of those classes where you learn more but score less. He really enjoys teaching it which helps a lot. Homework is very helpful in learning the material. Expect low grades but a large curve.

Pros: -Very engaging. -Really knows his stuff well -Grades testsassignments promptly -Curves class generously Cons: -Writes sadistic tests -Will sometimes mark you down if you don't do something his way, even if it is still correct.

This class is no joke. The material is pretty difficult but if you go to lecture and try and follow his examples you have a better chance of absorbing it. The homeworks take a long time, but if you put a lot of effort it tem and score well (well in this class is 60%) it can really help your grade. Tests are super difficult.

Professor Lorentz is very dedicated when it comes to his class. If you have any questions, be sure to ask, and he is always more than happy to help. With that, he is also a tough grader, so projects and tests were graded on his own accord. But if you attend lecture, and work on the projects on time, you will do fine.

Lorentz is very good at teaching. He provides challenging projects but he does give you plenty of time to do them. His tests aren't too difficult if you paid attention to lecture and he is always willing to help you understand the material. The class is easy to pass but it is challenging to get an A.

Phew! I barely passed this class with a C-. Definitely one of the harder classes in the computer science major with tests averaging between 30 and 40 percent. Large curve given at the end and Lorentz is a pretty cool guy. Not much homework during the semester but the tests are impossible unless you know the chapters inside and out.

Prof. Lorentz is amazing. We had 5 projects and 3 tests. His class is definitely hard, but if you want to learn the subject he is the one to learn it from. He tries very hard to make sure you get it. He is always available through Moodle or email to help as well. The class is curved, so try hard and you will pass. Really enjoyed this class :)

Great guy, not so great class. He teaches really simple stuff in comparison to other universities (check out the MIT & Berkeley lectures on YouTube), but then tests if you can apply that knowledge at a much higher level. This results in a lot of confusion during homework and exams. He explains the reasoning afterwards, but by then it's too late.

Very nice guy, always willing to help. Wants things done his way. Programming assignments are pretty easy, & I barely had any prior programming experience. The first midterms are based on the book & lecture, so focus on those. The final was difficult, so definitely study MORE than what he taught you. Be prepared to write code & do Big O analyses.

Lorentz's pop quizzes don't matter much towards the grade, but they and the exams are very difficult. He does give a large curve though. He is very helpful through moodle and in class if you ask him questions. Book is necessary, there's a pdf out there for it.

I barely passed the class, even with the large curve, but Dr. Lorentz is an amazing teacher. He is very helpful and you can see that he enjoys teaching. It's a difficult subject and the test scores were low overall, but you come out of the class feeling like you learned a lot. You have to read a lot and truly understand the material in the book.

Prof. Lorentz is one of the very few (and I mean very few) professors at CSUN who will actually teach you how to think like a computer scientist. His classes are very challenging, yet fulfilling. I recommend that anyone grad-school bound should take at least one class with him. He'll prepare you well.

This is one tough class, Lorentz really teaches you how to think. Massive curve at the end so don't be discouraged if you get low scores on his exams/HW. Expect to put in a lot of time studying to score in the 30-60 range on exams. If you do well on the final expect to pass the class.

Lorentz is not a bad professor. If you make an effort in this class to understand the concepts, you'll be fine. Make sure to complete the hw and all the practice problems to get as much practice as you can before exams. Trying to catch up in this class is not easy so do not slack off. Learn how to answer the problems as he would answer them.

Lorentz is one of the better instructors at CSUN, but 256 is a unique animal. His lecture style relies on student input. PARTICIPATE in the class discussion, don't be afraid to sound stupid. Constant engagement is vital! Don't get down on test grades. I didn't turn in homework, which is why I got a B+. Do the above including homework, get an A.

It's a tough course and despite how harshly he grades, he does curve incredibly because his primary focus is to get you to change from just blindly memorizing to thinking. COMP310 is a hard course, but he made it a really enjoyable class despite the hardships of learning the material thoroughy. He will respond to emails and canvas topics too.

This class is intensely difficult if you're like me and do not put the actual effort into learning the material. This is not a professor to take lightly he is tough but fair. It takes massive dedication, and you will absolutely learn. This was easily the hardest class of my life, but he curves and is willing to help outside of class. Very friendly.

The material itself is hard, he is also really tough, but he curves and he tries his best to explain things. The people complaining about his lectures either weren't paying attention or don't understand the difficulty in explaining data structures to students. There's a lot of outside effort required, but that's because of the class, not Lorentz.

Professor Lorentz is a wonderful professor. I feel that I have learned more in his class than I have in my previous computer science courses. Although he does have very difficult tests and projects, if you put in the time you will pass. Honestly, if you try in his class you will not only pass, but also learn a lot of real world applications.

Awesome! Had a Blast got an A. Passed with flying colors No probs Ez... For Reals Ez

Easily the best Professor I've had throughout my studies. Has a mastery of algorithmic programming, and gives very clear lectures where even very complex algorithms can be easily understood. Though you absolutely must take notes! Some algo. variants he lectures on can not be found on the internet and are barely mentioned in the book. Curves tests.

Professor Lorentz is a truly inspiring and wonderful professor. Whenever I have issues with my code he is easily accessible via e-mail and Canvas Discussions. He also is trying his best to make easy-to-understand lectures for us even during this difficult time. Highly reccomend.
