I told you in the Greek for Beginners page that you'd need to actually take classes first because of how different this language is, but at this point you DO NOT need to.
Again, if you still want to sign up for our Intermediate Greek Courses because you actually need the weekly commitment of an actual class or whatever the reason, we'll be more than happy to help you out, but as you know, I appreciate honesty and you don't necessarily need classes once you get to this point.
Even on this level, you shouldn't worry about your output (you should actually never worry about your output regardless where you're at, since this is a natural consequence if you follow the right principles). If you can't really communicate yet, all you need to do is keep getting exposed to comprehensible input in Greek, it's that simple.
Let's go with the free videos and resources first of all:
INTERMEDIATE LEVEL VIDEOS AND RESOURCES TO LEARN GREEK FOR FREE
I've personally used most of these resources (the ones I have not are actually similar ideas) and I can guarantee they were tremendously useful on my journey to learning different languages.
As you'll hear me say over and over again, give them a try and tell yourself the truth on whether you actually understand a particular resource or not. Remember that comprehensible input is the key to the entire process and that the fact that you didn't understand a particular resource doesn't mean you're not talented for languages, you're not good at learning them..., it just means you didn't get to that point just yet, you'll eventually get there later on.
INTERMEDIATE LEVEL GREEK COURSES
Once again, our great native teacher Anastasia will be happy to help you out privately or in group classes if you're looking for Greek lessons online. And you'll always get a free first session for you to see how it works beforehand, like I mentioned on the basic Greek level as well.
And finally, let me remind you that I believe classes are not strictly necessary at this point, but that decision is obviously up to you, we're here to help you truly learn the language in any way we can.
