Well yeah obviously there'd be some variation in the results, the test isn't exactly definitive.
Especially if, like me, you look up many the words in the boxes you don't tick. Then if those words came up again my vocabulary would magically jump by a large amount despite only having learned 10 or so new words.
34,500! I'm pretty happy with this for now. I've been reading a lot more lately, and I've also made a habit of writing down any word I come across that I don't fully understand the meaning of (or have never heard before), then looking them up at some point. Improving my language skills is something that I always strive for, though I didn't think that roughly a year's-worth of very lax, very scattered (but generally consistent) studying would yield this much of an improvement.
Then again, it's a quick online test and probably isn't that accurate.
Wait, what am I doing? I'm supposed to be improving my French, and instead I'm wasting my time with this wonderful language.
