This test measures your ability to memorise and update information.
Letters are presented sequentially and you have to determine
whether the letter currently shown matches the one
displayed two items ago.
Press
A if the letter matches the one two items ago.
Press L if the
letter does not match the one two
items ago.
Try to be as accurate and
as fast as possible.
Note: The task is
case-insensitive, so it does not matter whether a letter is displayed
as a capital or not to be count as a match.
