Just a curious note about some of the questions:
"Lucky" Q13: falling *is* an acceleration (9.8 m/s squared). There must be something I am missing?
Q16: is it possible that some students fail this? I know, in MX we use decimal system, but it seems so straightforward/intuitive to me, that I find the question quite curious.
Finally, I would most definitely fail the test! ;)
