Is there any way to program a calculator to hold information like notes or short chains of words that you could then bring up in a test?

Yes.

Enter the following numerals:

58008

Turn calculator upside down.

you can assign certain phrases to number inputs i think

or delete system 32 on calculator, that always works

You can put this code in 11669x3 hit = and flip it upside down. Read the code and follow the directions. This helped me out back in school.

almost done with a degree, don't think ill pass and im past the point of worrying. hopefully my other plan for life will work out. also i might lose my shitty part time job and i dont care.

use a scientific calculator, you can put anything there
