Excel

I had to use Excel alot this summer at my job at an insurance company.  they kept track of all of their data on spreadsheets and honestly I had some trouble manipulating the data at times due to the formatting they used.  Now that I know the controls to the program better I feel more confident that I could manipulate formulas and formats more adequately.  I used to have trouble making absolute cell references and I would spend way more time than was needed formating a formula for each cell.  Knowing what I know now I would have been ten times more efficient this summer.  Overall Excel is a wonderful program to know how to use as it organizes and provides avenue to analyze data that might otherwise be convoluted and confusing.
