He did make the class fun and interesting, but so wat, he's a hard prof. He expects everyone to know the previous yr's chem courses material and put them on tests without reviewing those materials in class. His notes are all over the place and very random. They didn't help me to study for tests. My grade from his chem class is so far the lowest.

He is one of the most enjoyable profs at York. His personality will make you WANT to come to class. The only problem is that his tests are KILLER!! Our class average was always at least 10% less than all of the other sections. In the end, if you want to have fun, take his class. If you want a good grade, then don't.

Overall excellent. His first test is hard for the ones who used to rely on the "just-sub-it-in" strategy from highschool. It's easy if you have the clear logical connections on the topics you are taught. His lectures are enjoyable and clear, but often too fast to digest it on the spot. You will probably need quite of intensive independent studying.

Dr Pietro was the first prof that made me love chemistry and see it through a whole new wonderful perspective! Although his tests may seem to be tough, if you attend class and understand what he discusses, then you'll be able to overcome them. Also, do the problems and example problems in the textbook for each chapter!! They'll help you pass!

One of the hardest Chem 1000 profs. In class he only does examples and does not at all go over the PowerPoints or concepts on how to do the examples.

WARNING. DO NOT TAKE THIS PROF. He doesn't even know what concepts are on the exams & teaches whatever he feels like teaching, which is completely useless. He doesn't record lectures at all. TRUST ME NOT WORTH, I started attending another prof's lecture, & I understood the content better than when he was teaching me. Take the course with Tihana.

Professor Pietro is passionate about chemistry but is not the best teacher. He often over-complicates topics or neglects to explain them. However, he does have regular office hours, so he can answer any question. Still, I would recommend going to another professor, preferably the CHEM1000 course director.

He clearly loves chemistry. The slides alone can be hard to follow but the course itself is beyond easy as long as you attend lecture or skim through the textbook. Real tests were same difficulty as practice tests. He often would go on tangents but always clarified beforehand that it was not testable. Weekly quizzes are annoying, but free marks.

Coming from someone who found grade 12 chemistry extremely easy, in his class I had to teach myself everything. He also doesn't know what's gonna be on the midterms/ exam so he teaches completely unrelated information that you don't need to know, while barely discussing the topics that will be tested on.

JUST RUN !!! If YOU are a first year student and thinking that lets give him a chance just don't take him please try literally anything but don't take him as a prof u will cry and end up hating chemistry and HAVE TO LITERALLY DO EVERYTHING ON UR OWN. The course itself is easy and midterms are also easy only if ur grade 12 basics are clear.

Lots of homework
