Really nice guy, good prof.

Very helpful and explains concepts well. Easy tests too.

Very helpful, an all around great prof.

A good prof, he tries hard to make sure students know the concepts. Best of all he wants people to do well in his course, and will provide as much help as you want.

Has a fairly thick accent, but he honestly tries to help students, and he get's to know everyones name!

Good Teacher, explains concepts pretty good. If you don't get them he will make sure you do and then repeat if u don't. Tends to care about his students unlike most comp sci profs. He wants the best for you and is fun in class.

Grammer is a bit off somtimes but other than than is OK.

One of the best profs Ive ever had, he may have a strong accent but he is smartest and nicest comp sci prof in lethbridge.

The class was a joke. People were out of control, and some students were even a bit sassy back to him. The course was structured alright, but his classroom management skills were poor.

Good prof. Likes his students, and enjoys having fun. Smart dude. Teaches very well even through the thick accent. BUT his exams are hard, and may catch you off guard. But he gives extra marks out just for going to see him. cool cool!

Chali will help u with anything, it doesn't matter if he is teaching it or not

Exams were surprisingly hard, but he is one of the most amusing prof's i have had... plus he takes great interest in his students, working very hard to learn everyones names at the very least.

Great Prof, will always help you with anything. Can explain well, just make sure you pay attention in class - or he will have your a$$! Tests pretty hard, but marks easy

The guys is awesome...he jokes all the time. And it's cool how he tries to remember everyone's and name funny when he starts calling everyone Jeff. The teaching is clear and he will try to make you understand. If you get a chance take his class.

Chali is a very nice guy. He'll take his time to learn everybody's name (if he doesn't know yours he'll call you Josh.) Also, his office door is always open for students who need help. He teaches course content very effectively, still, don't underestimate the difficulty of the final exam. it's hard.

He is a very talented teacher.

Dr. Chali is awsome, he is an excelent prof. I encourage all my school mate to take class with him.

Amazing Prof.

He is great! He respect every student.

--what r u doing we still have one more minute! --so~is that ok? --stop sleeping in my class JS! don't look at me like that! --and so on and so on he is a good professor, not only good at teaching, he also cares about his students. I will always remember him, a good teacher in my life, he lead me to the right track on studying computer science.

Great, prof. Classes fly... even Data Structures and Algorithms classes. Hilarious: stops mid-lecture to ask about your weekend or your hair. Offers all the help you can handle outside of class and sometimes extra marks. The department could use more teachers like him.

Good prof. He was helpful and the class was extreamly easy. The text book wasn't the greatest.

AWESOME guy! Try's to remember's everyone's name and interact's with students well, accent is thick but will help you whenever needed. Exam's are easy Quote: "Who's eating an orange in my class? Well, uh, I, hope, you are going to share that with everyone...I'm kidding haha"

Fun Class, Taught from textbook,Willing to go out of his way to help, staying after hours and would help you understand any concept you needed, Wants people to pay attention to class, always willing for class input, and if the class needs something he will change the structure for them. Great guy, Willing to take future classes from him

Excellent professor. He is extremely helpful. He makes everything very easy. Exams are also easy. It's easy to get the highest grade in his course.

Amazing prof. Take as many courses with him or Howard Cheng as you can!

A great prof. Really helpful, encouraged questions.

First impression, he is this VERY hard to understand Russian guy. I remember thinking I should drop this course after the first day. However this professor is incredible. Once you can get through his accent, he is super helpful and caring professor. The content can be tough at times but the professor will always be open to helping. Great professor

By far the most excitable and enthusiastic professor I've had! Very cheerful and more than willing to help you with your assignments. The course load can be heavy at times but still fair. The assignments and exams are straight forward and reasonable. I'd definitely recommend him as a professor. His accent might take some getting used to as well.

Great prof! Super helpful, and not to mention he has a great sense of humour. Oh and his tests are pretty easy! His accent is a little hard to understand though, and there is sometimes a bit of a language barrier when students ask questions.

Great prof. He's funny and helpful. Makes class very enjoyable. I would recommend him to anyone interested in Computer Science. Just be aware he has a heavy eastern european accent and there is a little bit of a language barrier at times, but don't let that dissuade you from taking a course with him.

Yllias was a fantastic prof!! He made it his mission to remember everyones names and he wasn't afraid to throw in a joke here and there. He is a little hard to understand sometimes, but he was a really nice guy who was always wiling to help whenever needed and often visited the lab just to see if everyone was doing ok with his assignments.

He is the greatest prof I have ever seen, discusses programming clearly, makes everything easy for you. The only thing you need to do is listen to and follow his lectures and you would get an A+.

If you're not in computer science, this class is probably going to be hard no matter what. Some people just can't think logically. Yet, if you have a basic understanding, Dr Chali is a great prof that will light heartedly discuss and teach fundamentals of programming. He has an accent but makes up with shear time given to students outside of class.

I graduated with my degree in computer science in 2004, I took many classes with Yllias. In-fact I ended up basing much of my 'school path' around which classes he taught. He's a great professor who really cares about the material and the people he teaches. If you show interest and respect he'll do everything he can to help you.

Great Prof when you're in class, but the assignments take 10+ hours each week and the midterm + final had material we never covered on it and were marked in a totally asinine fashion, screw up once and the entire 15+ mark question is all wrong, small errors are bound to happen when the exam makes you write a program on paper.

Amazing prof, lectures were so helpful and clear that you would fall in love with the subject; would love to take his class whichever course he teaches. Keep it up!

Great prof, great course materials; he is a born teacher I think, explains things so clearly; tests were not so hard, not so easy; if you follow his lectures carefully, you would get an A+.

Amazing prof, best I have ever seen.

He is great prof who consistently checks if the class is able to follow what he is teaching. He's also puts in some silly examples of what he talking about to keep your attention, and if run into him outside of class, he'll see how you are doing, which is really nice.

Good teacher, accent is a little thick and at times can be hard to understand. Beware this class if you don't have very much computer science experience as the tests are hard and you have to write full programs on paper. Assignments also take a lot of time.

He makes the class really interesting, take all his courses folks!

Great sense of humor, lectures make a lot of sense and also get you good grades!

Has a little accent, but you get used to it. Overall, great teacher!

Loved him, loved the class. Affirmed my beliefs that changing degrees was the right thing to do.

Remembers everyone's names in the class, hilarious at times, at the end of the lecture you suddenly find that you learned a lot without any difficulty. Best prof ever.

Good choice! Teaches material well but sometimes hard to understand. I enjoyed his class and he is a funny professor. You must pay attention though to do well on tests and assignments

Hilarious, but if you have questions I would recommend asking the tutorial instructor, or the lab instructor. He will help, but it can be a little easier to understand what they say.

Hilarious prof who is clearly passionate and cares about what he's teaching. Makes sure everyone understands what is going on before moving to the next topic. Lots of examples and explanations. Highly recommended as a prof.

Best prof ever, he breaks down the class to the "for dummies" level, and keeps class entertaining. Would recommend him to anyone.

I genuinely wish all of my CPSC courses with him. He's a good role-model, ensure everyone in the class understands what's being taught, and is very approachable. He's very knowledgeable in his field and will often have light-hearted jokes thrown into his lectures to create a more comfortable learning environment.

He's an excellent professor! He remembers everyone's name in the class and the course material isn't too hard for people without prereq. However, his lectures can be a little bit more on the tougher side along with the way he words various questions/assignments throughout the course.

He is an amazing teacher who makes lectures interesting and funny. Occasionally asks to make sure that everyone understands hat he has just written down. The grade is based on weekly assignments, a midterm, and a final. The final was very hard and was a large part of the grade so study lots for it, but the assignments and midterm were easy.

CPSC1620 can be a very difficult class but Chali is the man for the job. Everything you need to know for the weekly assignments is taught in class, so SHOW UP and PAY ATTENTION! He writes the whole time so make sure to take accurate notes. I found him to be very funny and he wants his students to do well, but marks hard.

Chali was amazing. His teaching takes time to get used to but is great once you get into the flow. Can go pretty quick in class but will take time to stop and explain if you have questions. He is also super understanding in a one on one if you have questions about marking or assignment feedback. To top it off, his sense of humor is unmatched!

Ylias is single handedly my favorite prof I've ever had at uleth. He will stop his lecture several times to ensure his students understand material and leaves a lot of space for discussion. He teases students, but he's very light hearted and cares deeply about them. He moves fast and you need to stay focused to keep up. But you'll learn lots!

Chali explained everything pretty well, and always gave examples. If a student did not understand something, he would stop the lecture, and help the student. The assignments were always on the topic that we were learning that week, so as long as I showed up to lectures, and labs, they were not too hard to complete.

One of my first compsci professors I ever had, he was incredibly funny and always wanted to have the class engaged in his material. His accent and manner of speaking, while sometimes difficult to understand is a very charming trait and he does truly care about his students. I 100% recommend his classes.

I really dont understand the less than 3 star reviews, He is a amazing prof that goes into great detail about everything that needs to be done, everything is straight forward if you attend lectures with a positive mindset; the class will be the easiest A ever, you just need to apply yourself and practice what he says through the assignments.

Dr. Chali was good at teaching. Made his lectures as engaging as possible. I'm happy he isn't stuck doing research, he really does care about the students who stick around after class and ask questions, but if you talk loudly in the back of his class he'll publicly embarrass you. He did try to learn everyone's names, but he got them wrong anyways

Chali is a great professor, and other students seem to agree. He always engages with the class, and explains topics that students are struggling with. I had him for 1620 as well, and enjoyed that class too. People that are leaving bad reviews most likely don't show up for class, or don't read assignment descriptions, and have a skill issue.

One of the best professors out there, inspiring lectures, takes extra care to explain complex concepts, you just need to pay attention during class lectures and follow his guidelines to do great in tests. Highly recommended!

Great teacher and great professor.

Best prof this term. Spend time with students, and very passionate.

A great teacher and professor, passionate about his students, and doing his best to make them succeed.

Inspiring teacher, and very interesting and inspiring lectures. I highly recommend him.
