If you need a financial calculator and are wondering what to get, then this is the one. You can use it on the CFA exam and it has the combination buttons to save you from memorizing a few extra formulas for nCr! and nPr!. Also, a few tips to help you get it set up: I prefer floating decimals and AOS calculations which can be changed by hitting 2nd and "." (FORMAT). Change it to DEC = 9 for floating decimals. For AOS mode, hit the down arrow under FORMAT until you see "Chn". Once you see "Chn" hit 2nd "ENTER" (ie SET) and down arrow then 2nd "CPT" (ie quit). This is how mine is set up which is great for me.
