DS is due to take the 11+ the second week of September. DH has been working through prep books with him since last autumn, but they still have quite a bit to get through. They haven't finished the books and still need to take practice tests.
Usually, over the summer holiday, we visit my parents in the states for a week. DS absolutely adores his grandparents and looks forward to the trip all year.
DH thinks we should cancel this year to concentrate on 11+ instead. DS will be heartbroken.
It's also true that the secondary school we think likely will best fit DS is a nearby grammar school that is usually oversubscribed, so to get in, he would need to do reasonably well on the 11+. And, the nearby non-grammar school seems like it really, really would not suit him well.
I don't know what to do. DH thinks that if I take DS on holiday, I might be ruining his future. I understand, but also think that 1.5 weeks of lost study shouldn't be that critical.
YABU = Skip holiday this year, 11+ is more important
YANBU = Take DS on holiday
