Pretty easy, overall.
Calculus is fundamental in understanding more advanced math classes and forces you to think and approach arguments mathematically, which you could apply to other subjects. Also it is a relatively easy course if you keep up with the homework.
Learning about derivatives and an intro to integrals was the majority of the course. The concepts are not that difficult at all in practice. Some professors can make the theorems seem extremely complicated, especially with limits and derivatives. Just try to find the short version of these explanations so you don't get too confused.

Advice for students:
Keep up with the homework, the only way to understand calc is just by doing the problems. Once you can't do a problem ask someone to just do it for you and watch there process, than try to do it by yourself. Also I highly suggest PatrickJMT on youtube, his calc videos are lifesavers.
