4.5 out of 5

I would recommend this practice test to all candidate taking any SAS certifications and especially the SAS Base and SAS Advanced programming 
The questions are very similar
Answers are very accurate
The web interface and platform same as real
Exam structure is followed correctly to have real like experience
Good support (through email only, but still good)
And main, low price compare to many another resource available 
Overall 4.5 out of 5 from me, the half star less as no voice support, rest everything is perfect.
