The students of Hogwarts School of Witchcraft and Wizardry were taught a rich and varied curriculum. ... But those were, in a sense, the core subjects of Hogwarts: the English, maths and science of the wizarding world; the classes we're well-acquainted with through the adventures of Harry Potter.

Does Harry Potter go to normal school?

Yes Harry did go to regular public school before Hogwarts but Harry's schooling is rather irrelevant since he was raised in a muggle home rather than by wizards and knew nothing of the wizarding world.

Do people study at Hogwarts?

Although, keep in mind that the Hogwarts program is academically challenging - most wizards and witches begin their studies at ages 11 or 12, so the workload will be incredibly rigorous for older exchange students. Muggles are encouraged to apply, since we no longer need to worry about He Who Must Not Be Named.
