How difficult is it to get less than 30% on a PgDL oral exam

Waiting on my oral result which comes out next month. I got 80% on the multiple choice so I need a 30% to pass the module. But maybe it's hindsight and anxiety making the memory seem worse but I've really really botched the oral exam to the point where I couldn't answer multiple questions and guessed a few others which the examiners seemed skeptical about. I did manage to get some questions correct and make ok guesses on a few others but I just didn't anticipate enough of the questions due to a lack of prep... I'm a visa student so things could be very difficult for me if I don't pass and I'm kinda scared shitless lol. Someone assure me it'll be fine?

I was at ULaw btw
