Murphy's Law 6: Will we ever stop burning through threads so quickly?

How are they grading you? Is it like the IB where 7 is the maximum grade? Because at least here in México a 5 is fail (it is usually graded out of 10)

Disclaimer: I know next to nothing about other school systems outside México, so please enlighten me.

I think the grading is from 1 to 5, with 5 being the highest.
