Ask Amy: Mother worries daughter isn’t ready for college.

Dear Amy: My daughter is graduating from high school. She barely passes classes if she doesn't like the subject or the teacher. She doesn't bother with homework, and will graduate by the skin of her teeth.

She is great at talking people into giving her another chance and getting in under the wire. After many years of fighting about her grades and habits, I now stand back, give her hugs and am ready to let her fly (or not) on her own.

She has magically been admitted to her first choice of college, which is out of state, and it's expensive.

We have saved and have enough to cover her tuition, but I fear her terrible habits and manipulative ways will just end up costing us $40,000, and she won't have anything to show for it.

I don't think she's ready, but I don't want to tell her that she's likely to fail.

She has always wanted to go to college and will not even discuss alternatives, like a gap year program, where I think she would gain some much-needed maturity and life skills.

I can't have her live at home, either. I think she needs to get out into the world. Plus, I'd probably go insane.

Should I give her that chance on our dime? What can I do to help her get her act together? She's an amazing kid, but needs to figure it out. —Mom

Dear Mom: Let's review: Your primary concern about your daughter is how she manages to manipulate situations and people in order to squeak under the wire. And look — she has done it again! Once she barely graduates, she is being handed the prize. And you are willing to spend $40,000 in order to get her out of the house (you wouldn't be the first parent to do that...).

Given your high stakes investment in her future and your perceptions of her realistic chances of success, maybe you should not send her off with a hug.

You could give her two choices: A gap year program or at least one semester of community college where she takes and passes four classes before transferring to her dream school .

I'm suggesting that you make this uncomfortable enough for her that (after she pouts and acts out and threatens to join the merchant marines), she will come to you with realistic options and possible solutions to your shared concern. She needs to earn her way in.
