For parents who's DS have had 7+/8+ interviews at WUS please tell me what's involved as DS is at state primary and we don't know anybody who knows anything about the process. How do they decide which boys they choose? Oral comprehension? Behaviour? Spark - um what does that mean?? DS doesn't do a lot of extra curricula because I can't afford it. Does it matter he's not done Grades in music and in the county tennis club and we don't have glamorous holidays?
