It is quite likely she will never get it right and it doesn't matter what her class/feats/equipment/level is. From my own experience she could make tick marks on her sheet and forget to erase them, pick up a shield and forget you can't get the AC bonus with a 2 handed weapon, has kids/family/job and wont remember from week to week because she's there to socialize, is overwhelmed by levelling too fast, thus her numbers change before she can get used to them. The list goes on and on and there is probably nothing you can do about it.
You need to figure out how you'll handle it. That's my take.
You're absolutely right that she's never going to get it. I've been playing with her for over a year in various D&D games. It's not a matter of needing more time. She just has a lousy memory and cannot get to the point where this stuff is intuitive for her. It's not even that she's too busy, because I know she's not. She can memorize the same fact a 100 times and forget it a 100 times. End of story.
I was in an abortive Shadowrun 4E game with her, which we abandoned at her admission that she would never, ever, ever be able to remember the rules and didn't like the system.
As for handling it, I just need to be more considerate about when I open my mouth to comment on her handling of game mechanics. That's the only solution.
