Not too easy. Not too difficult.
I think it is important to know basics of statistics considering we deal with them everyday. I also think learning basic excel work is very helpful for productivity in any field that deals with numbers.
I learned that not everything on TV, newspaper, any type of ad relating to stats is not always accurate. A lot goes into taking a sample and they don't always show you all the variables. Also learning Excel was very helpful.

Advice for students:
Put the time in to learn how to be productive in excel. Listen to the teacher and figure out ways to be efficient. Don't just follow the teachers instructions, but make sure you know and realize what you're doing.
