In fairness to C&G, they make it quite clear that obtaining the 6035 certificate doesn’t make you a fully qualified plumber and any real college will tell you that as well. It’s these training academies that are trying to pass off that qualification as something that will make you a plumber after completion. The course itself was good and will help you learn the basics but further learning (onsite) will be required to become an actual plumber and they’ll tell you that themselves (C&G)
