GLDYQL Difficulty of Use? 

I would prefer to know the learning curve before trying anything new. How difficult was it to start the GLDYQL? Or does it need technical expertise or high level expertise? The evaluations that GLDYQL can capture are beginner-friendly, though I would appreciate the truthful assessments. Did you find it difficult initially, how did that make you know more about it? New suggestions on tips or warnings would be welcome.
