@Pollypocket81 as others have said, go on each school website and they will have a list which will guide or past papers. The papers do change on the website yearly so I recommend downloading the papers now and look out for the new ones later in the year. Do a Google search for previous years you should be able to get some. Pia Academy has past papers and an answer section which I used. Used Atom alot - paid for the full package. I would say invest at beginning of Summer for full package and utilise.
What it will.come down too is the following:
Timing - your child needs to try and finish the papers
Accuracy - maths, try not to throw away marks on the easy stuff, show working out
English Writing - good use of voc, SPaG and a coherent story
Tip: work you son through as many past papers as you can. I introduced timing from Feb 2021 very subtly so I could gage where he was at and slowly worked on reducing with no pressure which worked.
I went through the past papers of the schools I was interested in and spotted patterns of types of questions, so I would use other past papers to practice those types of questions. It's harder to do for Whitgift as they don't have a full paper for you to really assess that they publish.
Feedback from my son regarding exams:
Trinity had 100 verbal Reasoning questions in 1 hour (my son sat exams for 2022 entry).
Whitgift has a Critical Thinking part - my son said it was hard, apparently I was told he scored well. Its about how you think (problem solving) so can't be tutored for apparently
Whitgift- for creativity writing was based on a picture
We ended up with an offer from W which we grab with both hands
