Personally, I've always felt that the 12c lacks in many ways. However, with the fact that the recent 12c's are ARM-powered and can be repurposed, I wonder if some ambitious and technically savvy user might be tempted to create and load an extended feature set. It is easier to keep it down to the two versions of each of the allowed models thus keeping things simple for the exam proctors. Still, a 12c is a tempting option just based on the RPN aspect alone.ĬFAI doesn't allow other calculators because the logistics of tracking a multitude of different calculators is tedious. I haven't dumped my TI just because I plan on taking the CFA exam sometime in the next year or so. In practice, I am not against owning multiple calculators and I do have more than a few. Even solving for any TVM variable on the TI takes an extra step since you have to press CPT.

Also, the 12c doesn't have menus to have to worry about - all features are displayed on the keyboard. If you can memorize the steps for interest conversions on the 12c, then it might not benefit you much to switch to a TI - especially if you can fly along with RPN.

It all depends on how comfortable you are with your math ability and memorization of certain formulas. Yes, if someone can live without RPN, the TI might be the better choice.
