Reviews

Concise and good to follow along. Although it is a lot to take in under a short period of time.

Courseware was effective but would like to have some PDF material on BPML and XPATH

You get detailed labs to guide you through the technical material giving you a hands on method of learning otherwise difficult material.

Exit certified was great as it is very in depth and hands on learning which made it very easy to learn this type of work.

Course was great and the instructor had an answer for anything that was asked during the course.
