First teacher that's ever been able to make me enjoy math! I would sometimes skip school but only show up to his class because it was so interesting! His course was the first difficult course I've had in high school but boy did I learn how to a) do math b) how to study. Those who do all of the homework will do well, and most importantly, be totally set for university regardless of where they go. Thanks Gatti!

Below my post, you can see an example of a person projecting their saltiness instead of trying to fix their own incompetence. The tests and exams are all within class material, so maybe people should try harder next time instead of crying about it. Keep up the good work Mr.Gatti! #gattination

Mr.Gatti is a smart guy, and really knows his stuff, but in grade 12, you do NOT what to be in his class. Why? Well this is because the marking is insane, and extremely difficult. Unless you have a good tutor or are smart enough to keep up with Thornhill's math curriculum (Which is twice as hard as any other school) I suggest you transfer schools or take private school math. The excuses he gives is "we're preparing you for University". Thanks for preparing me for the university i won't get into

If I had a choice between taking another one Ghatti's classes and being saturated with brown gravy and locked in a room with a wolverine that is high on PCP, then I honestly believe that I would choose the latter of these two choices. Just kidding Ghatti is awesome.

Mr.Gatti is possibly the best thing that could happen to your life. However, he always picks on this one poor student just because he comes from a culture that supports Spring Break.

Mr Gatti was wonderful. He was exceptionally knowledgeable and was ALWAYS willing to go the extra mile for his students. I struggled with Functions & Relations, and he was a constant source of support. He was selfless in his commitment to us. If you needed help, you could always count on him to be available over lunch hours, before class, and after class, especially in the week leading up to a big test. Kind, compassionate, patient, dedicated. He is what every teacher should aspire to be.

Once you get on his good side, he's a good guy. If you get anywhere remotely near his bad side, he begins to spaz at you on a regular basis, and refuses to help you. Due to these differing personalities, he can be very unstable. Nice one day, mean the next.
