Effective method of preparing for IBM certification exams.

This web's practice exam for C2090-930, the IBM certified SPSS Modeler professional is worth every penny paid for it.
Very good questions as those all are either the same or very near to the real exam, also the method of preparing for the exam by taking practice exam seems very unique and effective. For me, this was very effective and I was able to score 89%
Thank to the wonderful team who have provided email support for to me during the preparation period.
