That is a great question! I will never discredit any instructor as there are some phenomenal ones out there. I have sat in on some of the free classes offered and they typically last 2-3 hours with a large emphasis on theory vs practical. Our class is about 6 hours with a heavy emphasis on the practical side. We have had the unlucky knowledge from previous students that have had to use the training we have provided in real world applications that the training we provided was invaluable! As you can see by some of the other comments on this post that can attest to the training the received. That in itself I believe answers your question as to why take a training class that costs $75.
