You might want to lay off on purchasing the STAT 211 book for a bit if possible. I took that class, and bought the book (which was expensive, new edition) and didn't look at it almost at all. I looked at it for a couple definitions, but no examples were given through the book. I believe STAT 211 courses all assign the same online homework which is where a bulk of the learning is done. All the information I needed to get an A in this course was in class. I am one of the most heavy book self learners. I love going back to the book and learning in most my classes, but STAT 211 was an exception. You may get a different instructor that bases more from the book, but just a heads up.
