Get over 250 CFA® 1 formulas on one comprehensive formula sheet.
Make sure you put in the time to learn your formulas off by heart as no formula sheets are allowed into the exam venue. A great way to learn your formulas is to copy them out. Once you think you know them, you can write them out without checking your formula sheet and see how many you get right. Have a look at the cfaformula.com Formula Test for a specially designed booklet.
