I'm a student myself, so its not too difficult to figure out what I would do with all of these goodies if they were mine.
The bourjois mobile lip gloss would be amazing as I'm always losing my lipgloss at the bottom of my bag. You can never seem to find the thing that you need. Saying that, I always know where my mobile is, so the lipgloss would be a cute charm, but always accessible. I'd also pick up one of the free mobile mirrors sephora is giving away that way when I'm on my way to class I can touch up my lipgloss as I go.

I'd use the Tarte cheek stain, as I LOVE stain, as opposed to blush in the autumn. You could use it as both a cheek stain, but a lip stain as well if you were going from class straight out to dinner or on a date and didn't want just your normal lipgloss.

The lip venom I have myself and love. However, I think sometimes its a bit too much and a bit too sticky to put all over the lips. I would put on my lipstick first, and then use it on the bottom and middle of my lips in order to accenutate them and make those areas fuller. I love the taste of this stuff tho! The cinnamon smell is so good!
