Frequently too, many Poles, I've found, estimate their English to be far better than it is
Really Lyzko? I have invariably found that Poles have an endearing trait of significantly understating their abilities - as I have often found to my cost on the tennis court :)
More often than not, the new learner brings along their A2 course book, and within 2 minutes we move up a level. To answer the OP, I'm forever stuck at the aforementioned rough and ready functional and (wholly inadequate) social A2 level - never did like the perceived non musicality of the Polish language, as opposed to Russian for example.
