Ba ii plus professional calculator

Hi,

Is anyone facing issues with ba ii plus professional calculator. Sometimes I have to solve a question multiple times to get the correct answer. Can anyone suggest how to fix this problem? Also, a few of the keys don’t get pressed easily.

Is the ba ii plus business analyst calculator allowed? A friend has given me his and the calculator doesn’t seem to have any problems.

Both are allowed. I have not had any issues, but as you said, keys are annoying. Just make sure you double check what you are inputting.

Thanks!
