This is so true, my science teacher does this, sometimes she asks a question, i say it right, then she says "no" and says the EXACT same f**king thing.
And she doesn't count it if you say it in a different way.
I had to find out the G's, it was 10KG
i did: G= 10N/KG
G=100 N
and she corrected me by writing the EXACT same f**king thing.
