very hard exams! watch out!

Really very hard tests!!!

Teacher is a nice guy but his tests are very hard! Answers can be subjective. Assignments solutions often have errors. You CAN NOT get an A+ in this course.

Excellent professor. The best on earth!

Great teacher. Cares about the students who wanna learn...all you gotta do is ask, he's always there for his students. Hard exams, that's true, but we're the ones that benefit from it in the long run!

I think he is an excellent teacher, provided you mind your business and do your work on time. Exams are pretty tough, but possible. One thing is that he is very approachable and helpful. If you put in some effort, with some help, you should do very well.

Sometimes isn't the clearest person in the world. However he will explain as much as is necessary. His exams pretty tough and he his damn annoying with assignments and deadlines. Only take him if u r willing to do quite a bit of work

He is very helpful and approachable. If you ask him questions, he will try his best to answer you. Although the midterm was very hard, he is an easy marker. So, it was not as bad as what I thought.

All in all, he's a good teacher. But be warned, he is boring as hell! Make sure u r motivated in taking the course he's teaching,otherwise u wont want to show up. Assignments and tests are hard, but that's what the curve is for. Otherwise he explains quite well and is a dedicated teacher.

He's pretty good. His midterms are quite tough though but Final exam was a BREEZE. Got an A- in here with him. peace.

Hard marker but very helpful. Very good nodes. His explanation is very clear and care about whether students understand lectures. One of the best teachers in concordia if you want to learn something from him.

good.

Pretty tough course, but he's a good teacher. His jokes can be pretty weak, but his lectures are nontehteless entertaining. I find it sad that so many students can only complain about how hard his class is. If you don't like to be challenged, then why are you in engineering?

let me list these points and u guys can choose 1) he is tough but even tho he is tough , his explanation in the class is super clear and he makes his midterms hard because he simply wants u to work in the way he explained the material 2)the final with him is always easy trust me 3)i got C+ in this class with him and i did learn alot with him

If you have the chance to avoid this teacher, avoid him. his exams are not related to what he explains "tough". They are a lot of professors out there you can learn a lot from them. Overall, you may learn from his lectures "but don't expect this will help you answering his exams"

Anyone who complains about prof Shiri is just a slacker. If you put some effort into the class, study and attend lectures, it's easy to get A+. There is no mystery in his midterms if you have paid attention. The material is straight forward and he tests you on what was covered in class and tutorials.

Dr. Shiri made this course very interesting and relatively approachable. More in-class coverage of some topics would have been nice, but overall, the course was well organised, and presentation was clear and direct. Exams sometimes pick on areas where students sometimes overlook the details, but you learn to pay attention to them quickly this way.

He really knows what he is teaching..extremely organized, confident and helpful.

I don't understand what these other students have with this teacher (I'm speaking to the '07 Fall class). This guy is great. Thank God for his slides which are excellent. I dropped this class when Ford was teaching it. I thought I bad and got a B. I'd definitely take him again.

Dedicated, clear, helpful teacher; tough exams but to the level of his teaching.

He's a competent teacher however, this is a very demanding course and the project will most likley take up a lot of your time. His midterm is the worst I've ever had, (37%) yet I ended up with a final grade of B+ so he makes it really hard on you but in the end you will manage. Make sure you attend the tutorials, it helps.

Very simple midterm and final. Took this course during the summer term, studied for about 2 days in total (excluding the assignments) and got A+. The professor is very clear and the lectures are interesting. If you pay attention in class and do the necessary work, there is not reason you shouldn't get a good grade.

Wicked teacher ! if you're in enginnering to have a good time DON'T take his class! But if you really want to LEARN, You won't find a better Teacher than him, He's really into what he teaches. Definitely 2 thumbs up for this Professor!!

Explains clearly and well, assignments are kinda hard but doable since you have enough time to work on them. Killer exams and Annihilation in the final, i don't know what the teacher is trying to prove by giving such hard questions, the final average was 28/60, the midterm average was 15/30... No partial marks, you either get full or zero...

He's an awesome teacher. He cares about his students and encourages them to work hard. Always available for questions. He knows his material inside out. If you want to learn, take this course

Take him if you can. Great prof but will make you study a lot. Read the book and go to his lectures. The MT is tough (but you can finish it in 40 mins) and the final is pretty hard too. Fair marker.

He's a great teacher and a very nice person. He knows his material inside out. Definitely knows what he's talking about and expects his students to actually learn some stuff (which is why you're in school people)!! Don't slack and you'll be fine. He's available for questions, and cares about ppl who care about doing well!

Excellent teacher. Funny, very clear, knows the material very well. Is not afraid to stray from the class material to answer a student's question, and will come up with relevant problems on the spot to go over as a class. He's fair, stays after class to answer questions and moves at a perfect pace. One of the best teachers I've had at Concordia.

One of the best teachers in the department. Explains the material in a clear & straightforward manner. As an added bonus, he's also quite funny and approachable.

Great teacher, one of the best in Concordia. Take him when ever you can.

He is one of the best teachers I've ever had. He knows pretty much everything in databases and he really makes you understand the material. His exams are hard. If you really wanna learn and you're not too concerned about your grade. Take him. Even if you learn everything don't expect an A+ though.

Very good instructor: Professor Shiri explains well and knows how to present his material. Attend his lectures and the tutorials and you'll do fine. Be prepared to work a lot - the course is demanding.

Great professor, passionate about teaching and challenging his students. Tough assignments and exams, but you learn a lot!

A great professor. The course material didn't gel together as much as I would have liked it to, but still learned a lot and enjoyed the course.

Not a great prof for Advance database. May be he has the knowledge but he cannot teach well. Exams would mostly contain Multiple choice questions but very difficult grading scheme. If u r taking his subject just study it from the textbook and only conceptually

Very sympathetic prof. Easy assignments if you make use of the assigned textbook. There are lots of abstract concepts. This is probably what makes his exams tricky when nerves are going. Very approachable and has a sense of humour. I've never seen him fail when answering student questions; knows his stuff! Team project; so lab time is a must.

Passionate about the material he teaches, which is the best thing in a professor, in my opinion. The class was on the difficult side, but that is largely because theoretical computer science itself is hard. Prof Shiri helped clear up confusion I had during his office hours, and I learned a lot.

Great prof to choose to learn about the material.. You may find the lectures easy because Shiri provides easy examples. When it comes with the midterm and final, he chooses questions that you may have never thought of or seen before.

Cool prof. Helps you as much as he can. Funny and witty. Course is very interesting. Midterms and finals are insanely hard, its impossible to understand the concept behind the questions. He plays with the words in questions, so read the questions very carefully. Otherwise he's good.

He is infamous for being a tough grader; That is not the case.

The lectures are boring but assignments really help you pass the exams so, do them yourself.

Very underrated prof. He is one of the good profs in the department. He makes the material so easy that you won't even need to open the book. His exams are easy too.

Currently have him for 335. This is one of the easiest courses i have taken so far. Very little mathematical background needed, most of the math is defined in class and builds up from it.

Engaging lectures and answers questions well. Covers the course material thoroughly and in an organized manner. Exams are well designed.

He's very good and makes the material clear. Good feedback on exams, knows the material inside out, explains everything well. The class is only doable with him unless you take Gosta and then you're on your own.

1) He speaks English. 2) He doesn't simply read the slides. He actually explains stuff. So by Concordia standards he is a great teacher

Dr. Shiri is a great teacher. He teaches well and he knows what he's saying. The class was 2h30 long and it seemed like half of that. He has easy assignments but tough/tricky midterms and finals. He will give you feedback on everything to make sure you understand your mistake. You can get a good grade if you work hard enough.

Midterm was easy, final was way too hard. Excellent prof though

Prof Shiri is the best math teacher I've had. He knows his material inside out, and more importantly is able to explain difficult abstract concepts with clarity. He's attentive to students that ask questions or don't understand material, asks fair questions on tests and assignments, and is a great lecturer. I enjoyed the class tremendously!

Good teacher for COMP 353. Tests all MC but fair. Fair final exam, fair midterm. Tells you exactly what sections to read in the textbook. Reading some parts of the textbook was useful, and the slides are really good too. The lectures are pretty good, but some material is dry. He is also accommodating if you have disabilities I would recommend!

The course has perfect examples of tricky questions that can be asked in an exam, but he explains very well how to spot these tricks and work around them. A teacher who's caring and effective at conveying his enthusiasm for the material. Assignments can be tough but prepare you well for the exams, which are heavy on multiple choice questions.

Pretty good prof, conveys the course material clearly. My only problem is that he's very, very slow. He takes an hour on slides that could be done in 20 minutes. It's helpful for some students, but a big chunk of us can't bear it. Still good though.

Not the most exciting material, but he taught it very well. Very fair tests. Likes tricky questions, but you'll get used to his style over the semester (write down the quiz questions & answers!). One thing: Beware of the crummy outdated Concordia servers, most of our project-related headaches were due to them.

Good professor. Assignment questions -> exercise questions from textbook. Study hard -> get good grades. Study book in detail/internet, just reading from his slides will not be good for your exams. Exams MCQ based/very tricky. Gives relative grades and is a tough grader. An approachable person and explains the concept in detail when asked.

he is an amazing lecturer and I really loved his exams, short and tricky. the course is very abstract but he made it very interesting

he is one of the best professors that I have had in concordia.

Exams are based on everything he teaches in class. You have to make efforts in the project allocated. (in any programming language). Make notes of what he teaches in class.

Good teacher who explains well and have clear guidelines.

A little tricky, like to make you think. One of the better profs in the Comp Sci department. Note that there's aren't many.

He's good at teaching but his exam was extremely hard as the average of the exam was around 50%. He likes the tricky questions so be careful on the details. Nonetheless, I liked his class.

He is a great lecturer. If you attend all his classes and take notes, you don't need to read the textbook unless you are unclear about a subject. He is very good at addressing your questions. He takes his work very seriously and you can't get an easy grade from him. you have to work hard for it. If you are here to learn, he is the one!

Dr. Shiri knows his material very well, every stuff is in his mind, his quiz is very trick, but he will explain it right after the quiz. His ppt is very readable. Just following his slides will be a good review material.

JUST TAKE HIM , took him in FALL 2021!! No one is better than him in 335, he made it so easy to learn the subject and it was so fun , exams were fair and it was a very good experience to learn from him .

The professor is highly knowledgeable. Knows his material well. If you attend all classes and do self study pro-actively, you won't need the text book material or even attend tutorials. He is very open to doubt solving, the assignments may seem tough, but if you follow through with them, the final exam and mid term will seem easy.

Everyone that is complaining about this professor isn't cut out to study computer science. This class is challenging but very rewarding. This professor understands the material deeply and is able to convey it to the class effectively. If you want an easy grade, don't take this class. It's hard but worth it.
