hello

i m just wondering, which one of them is allowed to use in Univ. Casio FX-991ES or Casio FX991MS ? I m Engineering 1 student. i hv fx-991es already.. will it work?

thanks in advance!!!

If it looks enough like the MS (black/dark blue), then you may able to get away with it.

However, some TAs/invigilators may not let you use the ES because it's technically not the approved mac calculator.

If in doubt, buy the MS.

Invigilators can sometimes be random people not even attending the school, i would suggest just getting the generic bookstore version so theres no confusion. These people are just following their jobs, and told that only one particular calculator can be used, i had the ES but i could never get a straight answer as to if it would be allowed so i returned it and bought the accepted one.

Invigilators can be a pain, especially when it comes to calculators. I had one guy who found a piece of tape stuck to the back of my calculator and he took it from me and examined it for a good ten minutes. It's not worth the risk of using a different calculator especially when it's only 20$ and you're going to use it for about 4 years.
