Apparently work in progress submissions of our assignments were graded by the percentage of their completion.

So yeah... there was no way of getting 100% unless you had the assignemt compete. Spoler alert! Nobody got 100%... even if all the assignment criteria were met.

And the best thing is that he got the percentages by asking each student after their presentation...

Now I get why he was boasting so much, that only few of his students get A.
