Calculus is really hard, but Paiva is an awesome teacher. You can actually understand everything he teaches (you just get a really bad headache). He is also a really cool guy.
Mr. Paiva is a great teacher you learn a lot.. But he leaves the class often.
Paiva is the man! He's the coolest teacher in the building, & I'd definately recommend taking him. You'll learn LOTS of calc and have a great time doing it.
I love Paiva. He is the best teacher I ever had. College math is nothing compared to what we did in Paiva's class.
