How to present photos for college application

[canonfaithfulforever]

i have applied for a college position and recently the college replied stating i would have an interview so could i bring a range of photos to show them, the only problem is i dont know what the best way is to present them.

i have selected 54 of my best images

the only ideas i have are:
1. print individually on 6x4 paper
2. have 9 photos per page on an a4 piece of paper
3. have 9 photos on a piece of a3 paper

any other suggestions or your thoughts
thanks
