jtyangel, I use Excel about 80% of my day. What you could do to give yourself practice is put your household financial stuff on it. Recreate your checkbook on it, putting in the plus and minus formulas. You could also build a spreadsheet, working off of receipts, to see where your money is going. Give each item a classification, like Food, Clothing, Entertainment, Toiletries, etc. in a column and then sort them on that. Add in a sub-total.
You are always welcome to PM me if you get stuck.
