RE:RE:RE:Q1 CallJ Law, couldn't agree more. I once was a school teacher, usually 5 classes a day, sometimes only 4. End of day --- exhausted mostly .... needed a nap. LOL. I can't imagine having ,say, 15 or even 8 lecture and/or presentation classes a day. That would be gruelling! I'm happy with what NEXTECH is doing ---- Wish they (the technology) had been around back when I was an instructor.
