Best tool to practice for SAS certifications

This is the kick start I was waiting for a long.. I got my first SAS certification. Was working with the SAS tools from one and half year and from last three months, I was planning for this new SAS certification, in fact, I have given the certification once two months back and failed and I feel this was due to my less comfort on writing objective tets. This test helped in that area a lot, also the practice test got very good questions and almost all relevant. 
I feel this is the best practice tool for SAS available as of now. Very happy!
