What order should the cards be in?

You can choose Aces-high or Aces-low, so either:
A 2 3 4 5 6 7 8 9 10 J Q K
or
2 3 4 5 6 7 8 9 10 J Q K A

What if I made a mistake?

The program won't know. It doesn't check your work.
If you can correct your mistake, do so and carry on.
If you can't, just refresh the page and start again.
