Calculators

I know that batteries are never fun to deal with.

However, what about the PRAXIS. We never need to have much in the way of batteries. Unless you are taking a math or science. Personaly, I suggest that you either:

A. Carry a second calculator.
B. Carry a set of replacement batteries.

personally, I recommend making sure that your batteries are fresh and you carry a second. One can never be to safe when it comes to the praixs
