Don't forget though that although each calculator might be flashing every 10s, 100 of them in an exam could mean a flash every 0.1s. Or are they accurately synchronised? I would certainly have found that distracting, just when you need to concentrate. Although controlling the LED on/off from PPL might be thought as compromising exam mode, I think two options might be possible, if the LED can be triggered and latched, rather than repeatedly switched on and off under PPL control. One option would be to flash a LED upon program completion. Another option would be to flash a LED if a divide-by-zero or other runtime error occurs... Provided the PPL cannot switch that off and continue a program, it will be unable to simulate exam mode. Speaking of exam mode, I would like to see an "I am not a student" setting... So I can stop worrying that one day I will accidentally press that exam button and lose the functionality of the calculator for however long it takes.
