I came here from Codecademy, where I was learning Java previously. When I joined this, I was amazed at how included and in-depth the website and course had been making it. But then I went past where I needed to buy Premium. I said no, not having the money too (same reason I moved away from Codecademy) and found I can no longer do any tasks for about 6 lessons. This "Dark Matter" will run out and I won't have any more to continue. Are all the tasks Premium based? If so, I need to find a new site that can teach me Java.
