Would Alexander International School in Shaikpet take a State Board boy into class 8 next year?

Both our children are in an English-medium State Board school, and our son starts class 7 there next week. We are beginning to look at options for class 8 because his current school's middle section is small and he keeps asking for more sport than they can offer. For parents who know Alexander International School in Shaikpet: do they take joiners at class 8, is there a written test, and how many sports periods a week do the middle classes usually have?
