First, check what the test result actually means
Sitting, passing, or qualifying in a grammar-school entrance route is not always the same as receiving a place. Admissions criteria, oversubscription rules, catchment, distance, faith or other criteria, and local coordination can all still matter.
Treat the score as one step, then read the target school and local authority or admissions authority pages for how places are actually allocated. Official pages from GOV.UK, Kent County Council, Buckinghamshire Council, and Warwickshire County Council are typical examples of where that detail lives — always verify the live page for your area.
