Hello Shilpa,
Fort Mill has great schools so you'd have no problems. We live not too far away, close to Tega Cay, but on the other side which is part of the city of Charlotte. But I've heard only good things about the Fort Mill schools and we have a little girl who will be 2 in June, so we often think that by the time she's ready to go to middle school, we might move down to Fort Mill. We're quite happy with the reports we hear about Winget Elementary which is zoned for the Steele Creek area where we live now. Do let me know if you have any other questions and good luck house hunting!
