My learning is a ramdom thing, and I can say the same about my study scheme (which I don´t advise anyone to follow, ha ha.)
English is a hobby of sorts to me, at the end of the day it´s something that really unwind me.
Anyway, if I had to measure my progress, I could say it have improved a lot in the last ten years or so (remember, I don´t study in a - let´s say - formal way).
For the record, I am not against studying at English schools, I myself took a year-long course and it was conversational (or supposed to be, but at times we switched to Portuguese. More often than not.)
I might have ran the whole gamut of learning English, from bad to passable English, to a feeling of being good at it, to having met the learning plateau, and then to the admission that I don´t know much of it.
But I do like learning things, that keeps me going, it tickles my fancy. I know that there are many things to learn, long road ahead, but I am really glad to get where I am.
In the future, I might to take English classes, sit the CPE, TOELF, what you have...anyway, for the time being I study by myself (taking benefit from the books, magazines, sites, and other tools), and am a regular visitor to this site (and some other educational sites as well).
I am a student that enjoy a continuous learning and to share some my little knowledge with the fellow learners. That´s it, until next time.
