first quarter of the school year and im failing <3

hi so my school has this thing like performance task(PETA), written work, and smth i forgot and i took the test for PETA in math this week and I FUCKING FAILED SO HARD like i barely even got half od the score i got 8/20 AND THAT TEST IS 25% OF MY GODDAMN GRADE WHICH IS THE MAJORITY OF IT

PETA - 25%

WRITTEN WORK 20%

THE OTHER THING I FORGOT - 20%

THING NO.2 - 15%

HI OMG MY TEACHER JS SENT NOW AS I TYPE THIS THAT THE PASSING SCORE IS 12...

8/20...

40/100...

i need 60% (12/20) to pass...

THATS LITTERALLY LOWER THAN EVERY SUBJECT WHICH PASSING SCORE IS 75%

i understood the practice exercises i swear.. idk whwat happened, my solution made sense to me atleast and i used the exact same procedure as taught..
