webMethods Certification Exams

Has anyone taken the courses related to the webMethods Certification exams in the past year? Just curious if the courses and the exam have improved from 8.2 moving to 9.8? I am planning on taking the courses for either webMethods ESB or webMethods CAF to prepare for the certication exams in the next year, but wanted to see what others may have thought about the course and the exam.

Any feedback would be appreciated.
