SOF vs Unified Council: which olympiad suits your child?

Both run school olympiads on the school syllabus, with a certificate for every child. They differ in who can register, where your child sits the paper, the fee and the rounds.
- your child's school already runs SOF olympiads: registration is only through the school
- you want a second round for top scorers
- you want to register your child yourself
- you want the option of sitting it from home
- you want the lower fee: from ₹150 against ₹170
- you want a paper that says plainly there is no negative marking
