Answer:
It reached long-term memory
Explanation:
Long-term memory (LTM) refers to the stage of the memory model where informative knowledge is held indefinitely( the Atkinson–Shiffrin memory stages). This opposed to short-term and working memory, which lasts for about 18 to 30 seconds. In the above since Harry's information lasted long enough to finish his test on Tuesday( 10s of hours or there about) it must have reached his long term memory.
