The only time any of us "passes the AA class" is today if we don't pick up a drink. For alcoholics like me and many others here, "class is in session" and scheduled for every day for the rest of my life.
So far I've been to class every day for nine years - and I passed every one of them. There are others like Dallas who have been going to class every day for over 20 years.
OK I'm being silly - what I mean is that every day of my life is a "class" I go to. I call it the "Classrom of Life." Probably not what you meant, huh?
If you need "papers" to show you've been to classes, you have to get them from real live people and attend real live "classes" - we call them AA meetings. Or you might need to go to one of those "driving classes" because you were arrested under the influence while driving. I don't know why you need a paper or why you haven't got one, but check with your probation officer, your treatment counseler, the court in the city where you faced a hearing related to being drunk, or whoever told you to go to AA classes wherever you got in trouble. That is where you should find the paper and they also can tell you where are the "classes" you need to be going to.
You will probably have to go to meetings in your neighborhood. That's where you take your pieces of paper and the group treasurer or secretary signs them to prove you "attended" the meeting. It also helps if you don't drink so you remember what you're supposed to do, where you're supposed to go, and so you don't forget where you left your signed paper.
Hope this helps.
