one thing i found very irritating: in one of the tests that asked to type the group of letters where the image is from satellite, i find the group "y p k a 1" but the answer i got was 'wrong, group is "k p y a 1"'. if i am not mistaken, based on the mathematical definition of the group, groups "y p k a 1" and "k p y a 1" are the same
Updated to allow any order input; shouldn't be an issue anymore.
