There seems to be some confusion regarding this calculator and the ClassPad 400. I have both and the only difference between them is the CP400 has a qwerty soft menu keyboard, whilst the new model is non-qwerty. In all other respects they are identical apart from just one personal observation: the touch screen has been slightly changed for the CG500. First I noticed the reflection has changed - it's less sharp and there may be an extra element in it. The other change I've noticed is it is slightly less responsive to the stylus. Tapping did not always seem to register and sliding did not always highlight the whole selected. After using it for a couple of hours I went back to the 400 and there was a distinct improvement in response. BTW, I have two 400 and they are both more responsive than the 500.
In conclusion, if you must have a non-qwerty calculator for an exam, the CG500 is an excellent calculator which will last you many years. However, if qwerty is not an issue I would advise buying the CP400 model because of the marginally more responsive screen. There is no difference between the screens when reading the calculations made, they are both just as sharp. I was hoping that Casio would upgrade the chip speed on the 500 but they haven't. Compared with the TI-Nspire and HP Prime the Casio models are slower, but they are lovely calculators to use and remain my favourites despite their bulk.
