And even then it's not really learned in most cases because it has only been committed to short-term memory for the impending test. Ask the pupil to recite the same information a week after the test the information was needed for and you'll notice considerable deterioration of recall. A month later and you'll be lucky to get more than the first sentence! If language is learned properly and the grammar-scaffold is in place, you don't need to commit vast chunks of 'meaningless' TL to memory because you'll be able to pull together the language you need on the spot, almost as well as you do in your native language. This is as it should be, but somewhere along the line, this has all been forgotten and genuine learning and linguistic has been replaced by learning for a task that will be quickly forgotten.
