Everything that is done in excel can be done on the calculator, so there are ways around it if you're not comfortable using the program.  However, excel is a helpful supplement to the class and I would recommend proficiency in creating box-and-whisker plots, dot plots, residuals, basic stat functions (mean median, mote etc.), and other stat functions that are escaping me right now (but your teacher can tell you exactly what you'll need).  I recommend playing around with these options over the summer, or at least learning the gist before they are taught in class.  If you need more explanation let me know.

> 4.  Roughly are there any new Nemeth symbols introduced?
> 
> Answer: This is a tough question for me to answer because I learned the entire Nemeth code in the 6th grade, so I don't really know what would be considered "new".  Ask your teacher to give you the formula sheets that will be given with the AP exam.  Get that brailled and ask questions about any new symbols either over the summer (or before they are used in class).
> 5.  Is there any reason I would have to hand-draw a graph at any point if I have the calculator and excel available to me?
> 
> Answer: The class is mostly about interpreting graphs.  I can't say that your teacher will never ask you to draw one but if you're taking AP that's probably not a huge issue for you.  A detailed graph description will work just fine.  The more important part of the class is being able to explain the reasoning behind your graph.

> 6.  Are there parts of the course, minus inaccessible software, that are inaccessible?
> Answer: None that I can think of right now.
> Other Tips: Just make sure you have the book you need along with the student answer edition (so that you can see the correct graphs once you've finished problems).  Also, let your teacher know that it is imperative that they describe in class graphs done on excel.  If you don't understand a description, please speak up and say something.  A good teacher will make sure you have equal access to the graphs (whether this means drawing it ahead of time, asking a classmate to draw it for you while it's on the board, or going over it with you afterward).  Some teachers just want to explain the graphs and they're not so great at doing so, this would be a time to get a friend or someone who has taken the class in the past to draw them for you and ask the teacher for an explanation afterward.  I can't stress this enough, you REALLY need to know the graphs and the reasoning behind them so make sure you have access to them.
