No, there is no such thing as a school of Witchcraft and Wizardry. There is only and online school called Grey School of Wizardry which anyone can go onto and do courses and what not. Sorry to burst your bubble.

The most famous school of wizardry in the world is Hogwarts School of Witchcraft and Wizardry, from the Harry Potter series.

yes oberon zell ravenheart has opened world's first wizard school and its name is grey school of wizardry

In Los Angeles? No. There is an online school of real Witchcraft and Wizardry called the Grey School of Wizardry. It is cheap to enroll in, and provides a TON of material in its courses. It is a seven year program, each year costing around 50 dollars to join. Founded by Oberon Zell-Ravenheart, it is the most genuine school of Wizardry that you can find.

Given that magic is fantasy, there are no real schools located anywhere.

Harry Potter's school is called Hogwarts School of Witchcraft and Wizardry.

In the fourth book, Hogwarts hosts the triwizard tournament and students from two other schools come to compete. These schools are Beauxbatons Academy of Magic and Durmstrang Institute.
