Instead of just adding "Me llamo", I wrote "me llamo Juan" inadvertently giving the answer "Me llamo Juan Juan". This is accidental! Yet Kwiziq marks it incorrect! Almost certainly, this would never occur in a practical situation.
Also when using my tablet, I sometimes miss out a question by accident. Kwiziq should prompt that all the questions have not been answered. This is also accidental! Yet Kwiziq marks it incorrect!
