Rxtech exam practice questions: how representative of actual PTCE?

Hi! Title kind of explains itself. I've recently finished the training course for the 123cpht provided by RxTechExams; passing their final exam with a 92. I have been averaging 85-90 on their practice exams and I just wanted to know how similar the questions on the actual exam would be (its in 4 days) and if the questions that I am spamming would be representative of what I see on the test. I really dont want to pay the 65$ for the practice exam booklet thing PTCB has, so any alternative resources for practice would be greatly appreciated!
