I've been out of school 15 years but I'm going back. I have to take a statistics course to get into grad school. I've heard it's pretty tough with lots of formulas to remember. Any suggestions to what I need to know which may make this class a little less difficult?

Don't treat it as remembering formulas. Try to grasp the big ideas and the formulas will be easy to come by.
When you get to combinatorics (which is a big word for counting) think about sampling with or without replacement and ordering.
Ex. Flipping a coin repeatedly is sampling with replacement from a elementary space of {H,T}
If you have a box with colored balls in it, then if you don't replace a ball after choosing it then it's without replacement.
Problems stated as 'at least one' are usually more easily solved by realizing that :
P(at least one) = 1 - P( none )
I'm also an old fart who's gone back to grad school: in math! Email me if I can be of any future help. I specialize in statistics and even tutor in the subject....

Join a study group or hire a tutor. Statistics isn't that difficult, if you have someone explain things to you. I spent alot of wasted time trying to figure out things for myself. Once I made sense of it, it wasn't so bad.
