Should I offer free tutoring?

Hi,
I'm a part time tutor. There's one child who's been attending my lessons for almost 2 years. She's 14 and I like her a lot as a person. She's very mature and has good character qualities. She's highly intelligent when you talk to her.
Her problem is that she's dyslectic. For that reason, she usually gets "average" grades in Slovak language (I'm from Slovakia, so that's the language spoken here).

Next March, the girl (age 15) is going to take an important test which may decide wether she gets to a type of high school that prepares you for the university, or she'll only be accepted to a high school which prepares you for a manual job (waiter, cook ,hairdresser etc).

She really wants to get to the better school but she's concerned she won't make it because of her issues with Slovak.

Now, I'm NOT a qualified Slovak teacher (I teach English as a second language) , but I always got excellent grades. So I think I could help her.

However, I'm not sure her family could afford 2 lessons a week. Because I care for her so much, I'm thinking about offering her free tutoring in Slovak.
Is that a good idea? Or is it a slippery slope? What if I gave everyone free lessons? What if other parents find out and ask me for "charity" as well?

Would this be an act of kindness or would I just be "too soft" and not having enough self worth?

"Where there is love, there is no question."

Thank you, Beth. You're right.
I only asked because I have very poor boundaries and people have often abused my kindness in the past. I'm trying to learn what is and what isn't normal and how much can I give to people (because I tend to give 100% and get burned).
But in this case, I thought I should do this. I wanted to make sure and ask others if they agree so I don't make a mistake again.

You are a wonderful person. I admire you greatly for even considering this.

However, you need to think about the impact on yourself too. Set up boundaries and limitations. Make up a sort of contract of expectations. You don't want to find yourself in too deep. Also think about the economic disadvantages. This IS your profession by the way. It wouldn't just be that you are not collecting a fee from her but also that you would be unable to collect a fee from an otherwise paying client. Be fair to yourself hear Seeker. Consider the ramifications.

Is it possible to set her up a plan? Is this something she can do on her own through correspondence? Could you not set aside maybe one session every two weeks to mentor her?

Thank you, I'll think about all possibilities!

The girl is able and willing to pay so they won't be humiliated by accepting charity :-)
I'm quite excited about teaching a new subject and I'm looking forward to it! It's going to be refreshing :-)
