He is a very knowledgeable teacher but his exams are very hard if you only learn by heart but if you understand every little detail of the theory, I think you can do well. You get 3 bonus marks at the beginning of the semester and every time you finish last in the lab, you get - 1 but you get +1 for finishing first. I personally didnt like it because it made it very competitive and stressful since it put more emphasis on speed than quality of experiment.

If you cannot handle a big challenge, do not take him. Albeit your grades are not that high as you could get with other teachers, R-score is fantastic if you beat the average. Exams look easy, but is, de facto, hard.

Excellent teacher. Got him for two semesters. Hard marker, I agree, but if you are a hard working person, you will easily get over 30 R score with him. If you are hard working, you will end up with a lot of knowledge and a good grade at the end of the semester. Also, he is always available to answer questions.

His Exams are very hard, DO NOT EXPECT TO DO WELL IF YOU STUDY A COUPLE DAYS BEFORE, YOU NEED TO STUDY AT LEAST 2 WEEKS BEFORE. Very Theoretical, if you write something partially correct, almost 99% of the time you will get 0 marks on that questions. Don't expect him to give you partial marks for doing work on the page, he either gives you everything or nothing. Otherwise, very helpful. Don't worry if he's arrogant or mean, hes nice and he makes fun of you so you don't make the same mistake agai

He's really a great guy, I didn't like his teaching method (theory) however he's always there to help in his office (he had the most office hours per week amongst all chem. teachers!) What I liked most about his class were his labs. He just leaves you there assuming that you know what to do - which is hard at first, but it really helps you to start depending on yourself rather than depending on the teacher. Exams might be hard at times, but if you deserve to pass, you will without any problems.

Very knowledgeable teacher, but his exams difficulty is extremely high. Hard grader as well, either you get it or you get almost none. He will make fun of you if you ask him something you don't understand, but he is always there to help. Not a teacher I would suggest if you want a high r-score. Try to avoid if possible if you like chemistry because he will make you hate it more than ever. And he gives pop assignment and pop quiz too.

He is very unapproachable and swears at students. knows his stuff really well, but expects you to know it right away or makes you seem stupid in front of the class. if you want to do good in chem DO NOT TAKE HIM!!

Grade: 96 Final class average: 70 Absolutely amazing teacher. One of the best teachers ive ever had in my life. Right off the bat it is clear that Mauro loves to teach and is truly caring towards his students. He makes jokes from time to time which helps the class remain alert and focused on what he is saying. Great great teacher! Very very hard teacher because he expects you to understand the concepts instead of just throwing them up. Everyone saying he is bad is either lazy or stupid.

Mauro is the best (and hardest) chemistry teacher I've ever had. He is a very smart man and knows chemistry like you and I know the alphabet. Often times he swears and makes the class laugh. In order to succeed, you must really apply yourself. Advice: Do all the suggested problems multiple times, read the textbook and go to every class. That is the key to success. You will probably not to do well on the first test but once you get the hang of him you will succeed.

I have to say his knowledge on chemistry is profound. With that said, it is a blessing and a curse because on the bright side going to see him for one on one for help will clarify a lot of confusion. However, on the bad side, because he knows his stuff really well, his expectations on his students is really high. Therefore, you can expect a lot of hard work on your part to do well on his test (which are brutal), on his assignments and on the labs (believe they aren't any easier). Good Luck!!!
