The top score is usually 140 for each of the tests for a total of 420 but can vary each year
When DS did the test back in 2012 the max was 141 each for a maximum 423
We won't know that figure until after the results are released.
We also won't know what the required scores for a pass are until then either.
Last year you needed a total of 320 with each individual score 206 or above.
I totally agree that you shouldn't put a school on your SCAF if you haven't visited it! It may be completely unsuitable for your DC
There are many factors to help you decide...
All the open days / eves for the selective girls schools in Dartford, Gravesham & Medway are after the respective results days so we'll know in advance if there's any point going - I assume this is the case for all selective schools but don't know for sure.
To be safe we are also visiting all the non-selective open events in Dartford & Gravesham which are all happening over the last week and next 2 weeks
You should also study the over-subscription criteria for each of the schools to determine if it is worth looking at - some are catchment area(s), some are scores only (super-selective), some are distance, and some are a combination of all 3.
For example, DD took (and passed) the Medway test this year and although both RGS and Fort Pitt are good for us to travel to, only RGS is worth considering as they go by scores only whereas Fort Pitt go by catchment. So Fort Pitt is highly unlikely for OOC to get in the further away you are
