Greetings!! I feel really good that I made this investment of enrolling myself into bigclasses. Initially I was skeptical about its worthiness, but as the classes progressed,I became sure of its worthiness. You are really doing a great job of seamlessly taking us through the whole Cognos course. Your mode of teaching is so simple yet so enriching. It reflects your good command over the tool. I really appreciate the good work. (
