Passed Calc I easily. Failed Calc II on my first year (mostly because I couldn't understand how the theory would apply on a practical sense. As in exercises and such, the teacher didn't bother to do so and was all demonstrations. I HATE that and am terribly bad at figuring that kind of stuff out) but passed on the second year, though the subject in that semester was horribly planned. At least the teacher who gave practical classes was really good at that stuff and explained well the way theory was applied, unlike the previous year. With what I had prepared for the exams, I would very easily get, at the very least, a 16 on that (max is 20), but narrowly got a 10. I won't want to see that subject EVER AGAIN.
