Hi. Is it possible check my son score - I think of course is to low?!

(( He made nv and v reasoning on Wandsworth and last month he was very sad because his score was to low for Chestnut. I'm angry as well because I prepared him over one 1!! Every day, every second day he make bond tests about 0.5-1h. He got tutor over one 1 as well! He made huge progress and now ... Day before Wandsworth test I gave him 11-12+ and his score was about 95%!! Girl who's got tutoring with him and usually they got similar score - she made 30pkt more! My son was crying that his score got kids under national average

I don't want and I don't like compare people - especially kids but for me look like my son lost one page of test! Any chance for look his test or check again??
Thanks for any help
