auto date in cell when tick or cross entered in another cell

Hi all, I would like to be able to enter a tick or a cross (for right or wrong answer) in rows 2,4,6,8 and 10.
Also when tick or cross entered date to auto fill in 3,5,7,9 and 11 and If I need to change a wrong answer to right answer date to auto fill with new date if different from original.

Not sure if this is the right place to post this so sorry if is not the right place.

Thanks in advance.
