Is bootcamp an accurate representation?

hey guys, im about to retake my DAT and need some pointers, first time i took it i studied with booster and scored lower than my my last three full lengths, this time around im using bootcamp and im scoring alot higher and studying in more effective ways. Does bootcamp fairly represent all sections? RC and QR are alot harder on bootcamp it feels like. How accurate were your AA's on bootcamp compared to the real thing? was difficulty the same?
