Would someone give me their professional opinion?

im in training for this big company nationwide and everyone in the training has already signed a letter and got their health insurance with the company and everything is settled.i need to get 90% next week or above to p this training and graduate.My trainer never mentioned to me that i need to completely improve.but one thing is preventing me from getting that 90% or above and if not this week then they are gong to spend one more week with whoever didnt get that score...do u think from your professional experience that they might fire anyone in my cl if they didnt p this grade after they got them so setttled with the company and all ? everyone is worried and we need a professional opinion.thanks
