SAS Enterprise Miner 14

Hi there, I have used the service of practice for SAS exam A00-255 on 
I would say this is good at $41.30, good as they have tried to put all the question required for passing the exam, however there are some questions where the information such as dataset or reference is missing but not on all question so I feel this is a fair test set with enough question for practice and pass the certification exam.
