So I have a chance a passing this?

Hello!, my AUD test is Monday, I have put in 130 hours of study time but when I’m doing the simulated exam on the final review part I’m getting 45-50 %. I keep reviewing what I have done wrong but can’t get past this, maybe I over worked myself and thy why I’m failing, anyways you guys think I will have a chance?. Or should I start getting ready to take it again?.
