Everyone aims for 100%, but if my child comes home with a 98% mark on a test, then I would be very happy.
With marks that high, they would have to know the material very well, and probably made a silly little mistake. (like slightly misunderstanding a question, or not constructing their answer clearly enough)
I would then have a look to see what the mistake was, and then work with my child to figure out how to avoid the same mistake again in the future.
Some of the most valuable lessons I have learned in life have been from the mistakes I have made. (I'm sure there are others here who would agree with that statement)
