Speaking from experience of having heard this type of question before on this forum, I have to ask you why you need to get into a high school issue padlock using the 'fastest way' ? Seems a bit shady. Normally these combination padlocks do not have keyways in the back, but your post is suggestive of a keyway on your lock, which tells me that it is an institutional lock with a master key override (in case a student forgets the combination.)
We follow some basic yet sacred tenets in the locksport community, one of which is "you don't pick a lock if it doenst belong to you, even if it was issued for your use, or it is a lock on an apartment or house you rent, or an office door to the office you work in" (That's a bit more detailed than the actual "dont pick locks that arent yours" but we always have someone with the excuse that it really is their lock, even though it really isn't)
You will do well to leave that lock alone, and if you are actually interested in picking as a hobby, and not just jackin up someone's locker, then go to the hardware store and buy a real padlock with a keyhole, not just a combo lock that happens to have a little tiny keyhole in the back. Also, to answer your question, hairpins are for girls' hair silly; lock picks are for locks.
