Exercise: Compare exchange rates
Go to various sites, check the AAA/BBB exchange rate on each one of them. Print out the current exchange rate and also send an e-mail to yourself with the information. Also put a ARBITRAGE warning if there is a difference between the rates.
AAA and BBB can be any two currencies you are interested in.
