This is a class that EVERYONE has trouble with. Going to class provided lots of help, but the relative teaching methods which he excels at is compensate by a TOUGH exam (midterm and final).

Best professor (period!). He knows how to break down complicated topics and teaches them with such organization and clarity, and this just shows how well his lectures are thought-out. Nonetheless, it's a tough class, but if you write down all the notes well (including what HE SAYS), go to SL and review regularly, you will learn SO much.

Dr. Robidoux is one of the greatest teachers out there - this comes with a cost though as his exams are literally the hardest I've ever come across. Writing down every detail he mentions is essential, as well as going to SL if you want above a C. He made me love organic chemistry! I had an A- in the course but tanked the final (don't do that)

Explains everything clearly and goes through it all on the board. This is a naturally difficult course, but there are multiple evaluations. Definitely keep up with pop quizzes though, theyre worth 10% which may be important in the end because his final is long and he is super harsh in correcting. Lab is also a place to help raise your grade.

Loved this professor. Very clear in lectures. SL was very helpful and I went to all 4. Do his practice tests and go see him to get them graded beforehand to know what he exactly wants. He is very fair and gives you everything you need to succeed. Love this man.

I don't understand all the love for this teacher. I agree he explains competently, but he does not adequately prepare you for his tests (doing every practice problem and recommended problem isn't enough), and he is a very harsh grader. His class is incredibly discouraging. Maybe he works for others, but I would try to avoid him whenever I could.

Totally agree with previous comment. Even though I got an A I dont agree with his teaching. He doesnt give all resources to succeed. Attend SL if you want to pass/get good grade. I would add few more things about him: skips important parts but tests them on exams, which makes around 30% of problems unsolvable unless you know missing parts of info

If you're taking organic II at Concordia, Robidoux is a solid choice. He really knows his sh!t but sometimes has trouble explaining concepts to students who don't already have a good understanding of organic. If you get the choice, Wildes' classes and exams are identical but he's a gentler teacher and an easier grader. Go to the SL tutorials.

Robidoux is over rated.. His midterms are tough. He shows the basics in class but then puts hard material on the midterm. His way of grading is very strange too. You can get the correct answer but if it is not written "his way" he will mark it as wrong. Also students with disabilities everyone in the class will get your extra time too. Very unfair.

Robidoux is okay... I find he likes to test students based on traps and tricks which of course is not fair at all.. What is the point of testing a student's knowledge if all your testing are trick questions? Of course students will get it wrong. You definitely must attend SL's if you want to pass/do good in the class.

Worse prof I had. The modules seemed all over the place about random facts without any structure and understanding behind it, making the class not engaging AT ALL. Also, he did not assign a textbook, he assigned readings throughout the semester, many of which were in French and that he DID NOT provide a translation. Horrible prof.

Instructions for assignments in CHEM204 are extremely unclear, and graders are harsh--they remove marks arbitrarily, without even citing the "grading scheme", which ultimately is meaningless.

Lectures are all over the place with 50000 random historical facts and no theme nor flow. There's subtopics upon subtopics upon subtopics in each lecture that makes them take 5 to 6 hours each to get through. Excessive deadlines and assignments with ridiculously vague instructions - it's like taking a shot in the dark. Fix the course!

Best CHEM222 professor! The class is tough in a way that you have to attend it in order to pass, since most of the crucial information for midterms and finals is given in the class. He does not use books and instead gives free online material to read, which is complete and comprehensive. No real lectures slides. Exams and midterms are fairly hard.

I wish Robidoux would be more organized in giving proper activities that matches his classes. He is quick to teach during classes. Labs are the best but his tests are brutal. You really need to go to the SL sessions but before that, you need the basic knowledge of what his class entailed so you don't feel dumb going in sessions.

Listen, the people saying he doesn't care probably didn't go to class. This guy knows what he's talking about but does expect you to work. If you actually learn the material outside of class and PRACTICE you'll do perfectly fine. You really need to work for this grade but he gives you every single tool needed to do so- it's up to you to solidify.
