PLEASE I'M DESPERATE

I live in California and have failed the permit test 3 TIMES. My parents are pissed (rightfully so), I'M PISSED, and all my friends around me are passing. I study, I've read the hand book, and take practice tests. How tf am I not passing!?!?!?! My friends who don't have the best grades (dw they admit it as well and don't really care if I talk about their grades) are passing and I have better grades than them. If anyone has solutions to a GUARANTEED PASS the nest time I go, PLEAAAASEEEEEE TELL MEEE.
