Wow Onyx! I feel for the kids who have parents and schedules like that.

DD1 is in yr 4 at an independant private school and she does a few activities:

1 - Music bus - she does piano. Run during school hours and at school
2 - after school activities which is run by the school and sport straight after school - she LOVES sports
3 - Little athletics (of course out of school hours) and she wants to do swimming.

None of these are competitive and DD1 only does these things because she wants to.

DD1 also does not have a tutor. Math is not a strong subject for her, however she still maintains a 76% mark in all her math work. I did consider tutoring for her, but after speaking with her teacher tutoring a child with that kind of mark is not really worthwhile IMHO sure there is always room for improvement, but as long as she is passing her grades & doesn't have major issues learning I'm not concerned.
