All of those things are great. The one issue with them is without going into them knowing what you need to get out of them they are pretty useless. You can learn to program on a GrandMA, but unless you are going to come into contact with one that training is pointless. All of these courses are designed for employers to
send their employees to OR the freelancer who knows what they are looking for.
What is making you think you need more training? A GrandMA, Hog4, Hippo,
etc course is not going to make you get jobs any faster. Going to industry conferences will not help with that either. It is hard to get out of the academia "everything I need to know I can learn in a
book or class" mindset, but that is what you have to do.
ETCP is a long way off for you, odds are you are at least 2,000 hours shy of the requirement.
So, if you want to learn more, go get a job and start learning.

point in sinking any more money/time into sitting in a classroom and hearing someone talk. Get your hands dirty and just go for it.
