Yeah, I'm a comp sci major so I had to take through calc 3. Calc is "hard" in the sense that you need to go everyday, and at my university that's 50 minutes 5 days a week. It's "easy" in the sense that if you go everyday it's not hard haha. Calculus is a piece of cake if you go, listen to the professor, take notes, and do your homework. For those who it doesn't just "click" with, practice, practice, practice.
