Depends on the grade of the test. But for the most part if it’s below a 78, it’ll drop, If it’s above it’ll raise. It shouldn’t drop or raise it more than 3 point/percent.
It's NF3 (one Nitrogen and 3 Flouride)
Energy, mass, and the speed of light squared.
(E, M, and C^2 respectively).
Hope this helped! :)
