The Ultimate List of BA II Plus Calculator Tips for the CFA Exams

Awesome thanks for the stats information. I am getting x=9 S(x)=8.92 and standard deviation = 7.97

Hi @Ryan31! Yes, you’re right – we switched some of the numbers in the dataset and so your answer is the correct one. Have updated the article, thanks for the highlight!

For the AOS setting, the keystrokes are:
2nd -> . -> up arrow ->
2nd -> ENTER -> 2nd -> CPT

At least that’s how it worked on my BA II Plus: https://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetId=68618

Is there a function that sums up all the values stored in memory function?

Not that I know of. It wouldn’t make sense though – there are so many memory slots that you should rarely/never have to sum them all up at once.

In the BA 2 plus, is there a better way to use the memory function rather than STO 1/2/3 etc and RCL 1/2/3 when trying to bring the answer from one calculation to start another calculation?

Not that I know of, but I’m not sure why is that difficult to do. It’s not the same as typical calculators, but practice often and you’ll become fast at it.
