Fun teacher but a bit picky and long tests. He gets easier after midterms tho.

If you come to class and read his notes you can do well

Has excellent handouts, expects alot from his students but overall I learnt alot

Ray is a great teacher. No, he's not easy, but at least you learn something

lots of handouts....but we have to memorize all of that???hard sometimes...but overall...it's ok!!

He is VERY strict on marking, even spelling mistakes. He is very helpful and clear but is VERY HARD. You will learn a lot from him and he prepares you well for the real world. His 2hr exams actually takes 3hrs so use your time wisely.

DON'T MISS HIS CLASS. HARD HARD teacher, but you learn a lot......a lot of assignment, long and detail exams . Time management is very important in his class. if you are not ready, don't take him...so easy to get F.

HE'S FANTASTIC! BUT YOU HAVE TO BE PREPARED TO WORK,WORK,WORK! YOU WILL BE PREPARED FOR THE REAL WORLD WITH HIS CLASS. WORK HARD, WATCH THE DETAILS, DO ALL BONUS ASSIGNMENTS, AND YOU'LL DO GREAT. ASK ALL THE ?'S YOU WANT-HE WANTS YOU TO LEARN. GREAT G

This is one of his more easier and relaxing class, but it is stll HARD. I love his BONUS marks, so try hard at every chance to get them. He LOVEs DOS so he covers a lot so if you don't like the command line then STUDY hard, but it prepares you for UNIX.

i really like his teaching style, he would give you good marks as long as you do the work! His tests are not hard, you'll just have to memerize the handouts he gave you, then you'll did OK. I only got a B- in his class for im not a studious person.

probably the hardest teacher i have had a d.c. his assignments are very very difficult for very little %. his exams are even harder however i did learn lots and will never take another cisy class

One of the best instructors that Douglas ever has. I wish Dr. Van Dobosch can do just half as good as Mr. Yu.

Very good teacher,but tough!

Great Teacher. Expects alot, so slackers beware. Read and study the notes, attend the lectures and you will succeed. He does take the time if you ask for help. May seem a little intimidating, but he is very helpful

If you fail any of his classes, it's your fault, not his. You're there to learn, and sometimes you have to make an effort to succeed. If you sit at the back of the lab surfing the web during lectures, you'll get the mark you deserve, but if you do your part, which isn't much to ask, you'll succeed.

hard teacher, hard tests but easy work

A very organized instructor. Knows what he's talking about. He's ready to help if you ask for it. He also expects alot from his students. You're there to learn, not to goof off. You soze you lose. Pay attention, try hard on the assignments, and STUDY for the tests, and you'll get an easy A.

a hardworking and very helpful teacher

clear but a hard maker, always give hard tests, even small quizs~

One of the greatest prof that I have ever had at Douglas. You cannot find anyone better than Ray.

geez, we dont need to know DOS anymore. get on with Unix already. makes the test hard for fun. easy class for me cuz i knew the material before hand. but the teaching was horrible.

Are Ray's classes the easiest? No, but they are the most worthwhile.

If you're not in CSIS, don't take him. If you're in CSIS and want to be IT support, I highly recommend him. Tests and exams are very practical that requires troubleshooting skills, necessary for IT. If you think you have what it takes for this career, take this course to see if it is so.

Very nice prof. Easy marker and assignments and tests were so easy that you don't even have to study too much! I got an A!!!

He is hard!! He is very nice but he is really hard to get a A from. If you got a B you must've study hard, and you are from the IT world. If you got an A, let me know and I will worship you. If you want an easy A (what this class should be), avoid him at all cost.

was a nice guy and the material was basic and easy and the test material was often repeated and word for word from the notes, if anyone found him difficult, then they must not be very bright....

Very strict, but really entertaining. Pumps up how hard he is, but I got an A in his class which he said couldn't be done, I didn't even study that hard. Just study his notes and PAY ATTENTION IN CLASS, he will walk you through basically everything that will be done in the tests, just be very methodical and FOLLOW HIS DIRECTIONS.

Good guy but slightly odd, kinda has sort man syndrome. He goes out of his way to make the tests very challenging. I was frustrated because his tests are 50% memorization of abbreviations. Less about learning actual concepts and more about just memorization of definitions and abbreviations. Generally a good prof who cares about his students.

Great guy. If you slack off and don't attend class you won't do well. He shows you how to do his assignments during class. His notes are perfect, never needed to read my text book. I failed all the quizes and still got a B, take advantage of the bonus questions on assignment and use the study guide for the midterm/test!I would take him again.

He is an fantastic instructor. If you pay attention and listen to him, you will pass this class with flying colors. If you facebook and watch sports during class you will fail hard, and you deserve it. He doesn't ask for anything but your attention and attendance. And who knows you might actually learn something if you pay attention.

Raymond is a great teacher! Just have to pay attention in class and review his notes he puts onto the network drive. It is a very thorough list and he follows it quite well! Quizzes are not too hard as long as you review the acronyms and learn the definitions! It's up to you how good you are! Hands on teaching is great! He is fantastic!

Pay attention in class. He is tough and very challenging. Know your stuff or you can easily fail his class.

Great Professor, he test the material on the PowerPoint. If you pay attention and take notes, surely you will pass his course with flying colours. One of the easiest professors I have come across.

Mr. Yu is the most straightforward teacher I have ever had. He will tell you exactly what you must and mustn't do in order to receive a perfect grade in his course. There are many people who complain about receiving poor marks, but really you only have yourself to blame if you can't follow instructions. He also gives lots of bonus/attendance marks

If u like classes where expectations are clearly laid out for you, then take this class. He actually posts study guides for his quizzes (which are actually the same as the real quiz) and many of his exam questions can be found online on quizlet and are word for word

I received the grade I did because I barely showed up to class. The test and midterms are straight out of the textbook. There are group assignments (about five) they take some time but they are easy. Takes this class, if you actually put minimal effort in (unlike me) you will get an easy A!

Once you get to know Ray he is a good guy. Go up to him after class and have a chat with him about anything and get in his good books. He is still strict and wont grade you differently but he will help you a lot more.

HE IS AMAZING. THE BEST TEACHER EVER. SO CLEAR. IF YOU NEED HELP HE'S ALWAYS WILLING TO. TRY YOUR HARDEST. FUNNY. HELPFUL. VERY CLOSE WITH STUDENTS. HE QUIZZES ARE EASY. HIS TEST ARE HARD BUT YOU HAVE TO STUDY. HE'S EASY GOING. BUT STRICT WITH THIS INSTRUCTIONS. HE LAYS DOWN EVERYTHING FOR ANY ASSIGNMENTS AND IS VERY CLEAR. HE'S AMAZING!

Raymond's courses are great if you know what to expect. Studying relies heavily on memorization, and lectures are nothing too special. However, he understands the material is very dry and outside most peoples field of interest, so he provides opportunities for extra credit to help you out. He's a great person and easy to talk to. Would take again.

Ray was a great prof. He's very detailed oriented on the assignments, but he's upfront and fair about it. Tons of bonus marks to be had; on every assignment and he give "pop quizes" that are entirely for bonus marks! Tests are extremely easy and straight forward. He posts all his notes so you won't need to buy the book. 10/10 would take class again

very good professor

Ray is the easiest prof to take for 2200, easy A+, just show up. Memorize all of the answers to his practice quizzes to 100% all the tests he gives. Gives bonus marks for attendance and pop quizzes but they all start at the beginning of class so don't be late. All assignments are done in groups, but are super simple.

Raymond is awesome. He's a very nice guy and very approachable. I don't understand the bad reviews because he's a very easy teacher. Most of the class is getting an A with minimal effort. The work is unbearably easy. He provides surprise quizzes but they're bonus marks. He gives bonus marks very generously. I would take his class again!

Thank you raymond for the amazing semester. Raymond is very straight forward professor. He will tell you the rules, and you should obey them. FOR THE LOVE OF GOD please, if raymond gives you practice quizes USE THEM. You want to get a good grade? Use practice quiz and you will. Also, every assignment is done in groups... so choose wise

He is one of the best Prof. in Douglas College. He gives group project and presentation. He gives practice quizzes which is really helpful. He is very kind and funny. You should go with him if you want to get grade A. Juts little bit need to study that's it.

You would have to be a retard to fail this class. He LITERALLY gives the possible test questions with answers to them. You can memorize the questions and ace the tests or get above 70% if you half assed studied. And the tests are multiple choice/fill in the blanks... There are a few questions not in the practice tests but still easy 80+

Study Resources easy to find. Wants his student to know what's up in the field presently.

He was an interesting prof. Definitely very clear about what he expects from assignments and from the class. He gives pop quizzes on random subjects almost every class. Had quizzes/tests that were based on every lecture so make sure you go. Assignments took time and make sure you follow every direction he gives or you lose marks. Gave a bonuses

I really enjoyed his classes. Hes silly and caring. The bonus marks from quizzes are exciting to get since not a lot of college professors do that. Pay attention, show up early, do not slack off, listen to him and youll get a high mark. Effort pays off.

Having Raymond for the excel class was very interesting. It help me a lot in how the idea of excel work. I would recommend him as the excel professer.

Would you go for an instructor that doesn't teach you valuable lessons yet will give good marks or hard marker yet will teach you practical lessons? He may be strict with his instructions but you will learn a lot from this guy.

Ray made it very clear from the first class how he teaches and what he expects. While he is instructing the use of Excel he is also trying to show his students that high school is over and it's time to act like an adult. Show up on time, pay attention to detail, follow instructions and you'll be fine.

One of the best lecturers I have met in my whole education path. Yeah, he is strict, asks to follow instructions, has many assignments, quizzes, etc. But he is the only one to teach u how to prepare yourself for the next step. He is so punctual it's easy & interesting to learn from him if you follow him. Definitely recommend him for this subject.

He is clear about what he says. If you follow what he exactly says, easy to score. If not no excuses. He is bad but not bad the way someone thinks it is. He has his own criteria for marking and giving marks. He rewards the effort when proven. Gives bonus assignments and marks to have higher marks.

In my opinion, he is a great teacher even though lots of projects, asgms through the course. If you want to get a high mark, you definitely can achieve it by following his rules. Don't worry :))

Such an amazing teacher :))

The professor is a great and clearly cares about his students. He has multiple rules and is strict with them, but they are easy to follow as long as you carefully read the instructions. The course itself heavily relies on memorization of the textbook, so studying for Raymond's quizzes can be tough. The quizzes/exams themselves are not too hard.

Raymond is a tough prof yes, but it isn't difficult to get a good grade. Just pay attention in lecture take notes on what he says because it WILL be on the midterm. Follow every instruction on his assigments and double check and you will be fine. He responds to emails pretty quick so thats great. Overall I had a good expiernce.
