Kwikspell is a correspondence course in beginner's magic run by the Kwikspell Company. The course is designed to help adult witches and wizards brush up on their magical skills. Lesson one of this course teaches the student the correct way to hold their wand - "Lesson One: Holding Your Wand (Some Useful Tips)".
Kwikspell seems to be effective among wizards who, like Madam Z. Nettles and Warlock D.J. Prod have poor magical skills. However, Squibs who try it, like Argus Filch, find no results as they have no magical power.
