Does this girl like me? Most constructive answer gets 10 points?

yes she clearly likes you but its still early days, you havent known her long so you need to give it time and keep speaking to see how things progress. dont worry about making things happen too quickly, if you decide you feel the same way about her then ask if she'd like to hang out some time like go for coffee or to see a movie and hopefully things will become more clear from there.
