FlugzeugFuehrer,
thanks and best luck for you, too.
about ROT, it starts off really slow; even slower than lvl1 in CBTs and gets faster and faster by time. but its like 5 slow, 5 faster, 5 faster, 5 fastest. my advise; close your eyes and press earphone to your head.
about MIC, I don't know what they ask for LH but, it consists of a bunch of set of tasks. like, heading, turning; heading and descend, turn and hold altitude; heading, climb and cover your speed. the auditory tasks come in the last 2 tasks of test. a male voice reads numbers with different order and asks you to press the red button in every third sequential odd number, or green button in every third sequential even number, while holding your altitude, covering your speed and heading.
about your last question; they are all alike the ones given you in CBTs.
