Yep, age 16 and 12, Year 11 and Year 8. My eldest has 6 GCSEs/IGCSEs already and takes a few more this summer (we haven't made a final decision on numbers!). She goes to 6th form college in September which I know she is ready for and will thrive at. They were initially doubtful as to whether they would take her because she wants to do Drama and Dance and doesn't/ won't have those GCSEs. So they called her in for an audition in November and in the audition letter said they would let us know in the spring. I think they were utterly stunned by her. They sent her a letter offering her a place the next day! She's also applying for full time ballet school but we know that's a long shot.
12 year old took GCSE Physics last year and could do more but I am concentrating on DD1 this year. The nice thing with home ed is it doesn't have to be relelntless or as consistent as school. DD2 is very much doing her own thing this year, her music, dance and skating, keeping the maths going on mathletics, a bit of poetry and Latin with my mum, and that's it really. She reads lots of astronomy and science books and does lots of art and craft on her own steam. I'll pick up more formal stuff with her next academic year.
I work quite a lot. Mostly at home but recently I've got a job teaching in school part time, too. I worry a bit what the LA would say but the girls just get on whilst I am not there. They do their piano and ballet practice, DD2 does her maths, DD1 works through her GCSE stuff. I don't have so much input with DD1 nowadays - she's very self-motivated. I never thought I would write that when she came out of school at 12! Her main worry with 6th form is that she's been such an independent learner, it might take an adjustment.
We use quite a lot of textbooks etc and workbooks for Maths, English and Science for DD2. It's taken a while and some expense to find what suits them. Some families don't bother with them. GCSEs are easier as there are normally set books for the course.
DD2 has an enviable social life, surprisingly so as she was a very unsociable child at school. DD1 has found it harder, I think because she was older when she came out of school and lots of friendships were already very formed. 6th form will be good for her, I think. DD2 talks about staying in home ed until 18 which is fine by me. I have every faith in her to teach herself A levels in any subject :)
