I think it depends on how you test them and what preparation you have done previously. I gave my eldest a run of trail tests for 9 weeks leading up to the exam. We had done some prep work before hand but not a lot. They were strictly timed and strictly marked and the order I gave them is deemed to be that of easiet to hardest by many experienced posters on this site.
I have recorded them as I am using them for comparism for DS2 who is sitting the test this year. The scores are all percentage scores. You might find them useful.
The only time I repeated a paper was on the Saturday before the test and I had him redo the very first GL paper he sat. He had not done any long papers before this time.
His scores :-
Week 1 GLA 63.........SD 1 75 ...Combined 68%
Week 2 GLB 68.........SD 2 62 ...Combined 65%
Week 3 GLC 71........SD 3 76 ...Combined 73%
Week 4 GLD 85........SD 4 53 ...Combined 69%
Week 5 SD5 81..........SD 6 68 ...Combined 74%
Week 6 SD7 75..........SD 8 84 ...Combined 79%
Week 7 Walsh 1 66 Walsh 2 75 ...Combined 70%
8 Walsh 3 75 Walsh 4 76 ...Combined 76%
sat before test =
GL A 81% Walsh 5 76% ...Combined 79%
Sd are the Susan Daughtry multiple choice ones.
One of the reasons I am posting them is because my DS never managed to get a score higher than 85%. His combined scores never reached over 80%. He sat the test last November.
His Pates score was 237 i.e he only just failed to get into their top 160 and he is a September born child so standardisation will take off marks.
His Tommies marks were
paper 1 116 paper 2 117
I had been in a right old panic because he desperately wanted to go to Tommies and I was under the impression that he should have been scoring higher to get a place. Thankfully I was wrong
