Foundation etc first or eye makeup?

[TFuller]

I've noticed in our course notes we are usually instructed to apply primers, concealers, foundations and powders before applying eye makeup.
However I have noticed in Nathan's tutorials he mostly does the eye makeup first. Is there a general rule for either or does it come down to personal preference? Will we be marked down if we apply eye makeup first in future assessments?

Thanks in advance

I am not sure about your tutor but mine is Nathan and he said it's best to apply the eye makeup first to avoid fall out.

Holding a tissue under the eye as you apply the eyeshadow helps catch the falling shadow however I d like to apply most of my eye makeup first especially on the top lid.
