A big thing is that not every skill (indeed, probably most aren't) is worth practicing to 75%. 63% or wherever it is exactly that two pracs gets you is sufficient for most purposes.

Gain revert is your friend.

You can skip putting practices into some skills entirely, but there's not a lot of what I'd consider fat in the A-P skill and spell list.

Practice weapons from Balator are help with weapon skills, up to a point, if you're inclined to work on them.

There's help in the Consortium for magic.

All that being said I think something smarter like a human is a better first A-P if you don't feel like you have a pretty good handle on the class yet, exactly because you won't know yet what's skippable and what's not for your style.
