What part of Harry Potter is this picture?

This should be a still photo of Harry Potter and them learning magic in a magic class in Harry Potter and the Sorcerer's Stone.

My deduction process is:?

First of all, through Baidu Harry Potter movie encyclopedia, I found the stills of each movie. Only in the first two movies, Ron has this hairstyle:

Harry Potter and the Sorcerer's Stone are in class.

In the third part, Wayne changed his hairstyle.

Secondly, combined with the actor's facial age, school uniform, prone posture and prone desk, it is very similar to the first stills:

Look at Wayne's unhappy expression and your picture in the lower right corner.

So to sum up, I think there is a 90% chance that it will be the first Harry Potter and the Philosopher's Stone. I hope I can help you and adopt it.
