[PF]There's some way to get access to 2nd level spell without CL 3 or 4?

I think i saw feat or trait before but i can't find it.

There's something like that?

Precocious Apprentice (CA) is the big one.

Please note the "[PF]" Tag in the title.

In Pathfinder, there is no way that comes to mind.
The closest would be a Trait, Magical Lineage (http://www.d20pfsrd.com/traits/magic-traits/magical-lineage), but that is a Metamagic reducer, and will probably NOT work for whatever shenanigans you may be hoping to pull.

How about scrolls? Pool your gold if you have to.

NB: in Pathfinder Society play expect to be told "no".

Then you can come back here and tell us, and we'll all act like your fundamental human rights have been violated, and we are outraged, outraged I tell you.

Generally, you need 3.5 material to enable early entry, PF doesn't leave many cracks to wiggle through in that regard.
