Sorry, but there's no way in hell, especially in that scale. It seems like it's an in-class worksheet if you reference the title, and eyes drawn like that, no matter how much practice, would take days to be perfected like this one is.
Plus, the textures seem to be made with charcoal at parts.
If they are an art student, they might have charcoal with them. Also, on packets that continue for several days (like notes) this would definitely be possible.
It's on a worksheet. Most likely the eye is printed and the assignment is to finish the face or at least match the eye. The eye does seem to be copy-pasted from somewhere else, just look at the shading next to the inner eye.
