This is the first time taking a class with ONLC, so the experience was unique to me. I wasn't quite sure what to expect, but I am very pleased with this format. The instructor was very knowledgable, worked at a good pace, and most importantly, was very good at communicating with all the attendees and ensuring questions were answered. I would definitely recommend ONLC to others and I hope to have the opportunity to attend more training classes with ONLC

I would strongly recommend ONLC courses to other individuals who require additional software skills with limited time availability. The classes are exemplary and the class size allows for individual attention which provides a high rate of comprehension.
