What's a good way to help a friend improve execution of specials?

I’ve been teaching a friend to play SFIV. She understands the basics (normals, throws, punishing, terminology, etc…), but can only do specials about 40-70% consistently depending on which one. How can she improve her execution?

She mains Cammy, if it matters.

Tell your friend to go into training mode and practice each of those special moves on both sides 100 times a day.
