SD is 17 and last year of HS. Two years ago SD got into a huge Fight with DH and I refused to follow our rules and ran back to BM’s house. She has not been invited back. THANK GOD. SD has had Discipline and academic problems all through high school. Multiple detentions and a couple of Suspensions. BM of course makes bullshit Excuses for SD. First it was Because SD supposedly had depression. Then after we refused to let her back unless SD agrees to follow our rules it was because DH “threw away his Daughter”. 

Here is my Concerns. SD is badly failing her Senior year and it looks like she will not Graduate this spring due to her poor grades. Why do I care since she’s not our problem anymore? Well DH Legally agreed to split all cost of the children’s schooling Including college when he divorced BM years ago. Im afraid it’s going to cost us $$$$ to pull this delinquent out of the mess she made with her grades. I can’t see BM throwing in the towel. What I do see is BM pushing SD to finish HS somehow then off the college. All this will take a ton of money to pull off. 

So my questions are for kids that fail 12th grade do they repeat the year, summer school or have to get private study somewhere? What are the Options and is it costly? Does anyone have Experience with this and what was the out come? SD has NO Experience with anything. Never had a job except babysitting her cousins a few times.
