My arsenal: Summer Ammo, Shine, Instant Gentlemen, A314b, P97.
I’ll recommend a solo test first for everything you’ve got. 
For basic combo, I’ll go with the AMMO + IShine at 1 spray each
Summer Ammo/IG is the combination that leaps out as me as a smart, social, sexy and good to be around sort of mix.
Or IG/IS if you want to emphasise pleasant/youthful status.
Remember that Summer Ammo already contains a reasonably blanced proportion of TAA, which is the main component of IS, so unless you think it needs further steering in that direction, you don’t need to add (or add so much) of it.
If it is the first day it really depends on what kind of tone you want to set. I would at least use the S.Ammo if anything. If you really want to make an impression I am leaning towards S.Ammo at 1 spray and then IG at 1-2 sprays is where I would start. This should be balanced and will not only help with the attraction from the women, but the IG should help get you respect from guys to and all your teachers as well. You would get a good start with everyone with this setup, not just the women so this is my pick.
