It doesn't work that way.
The standardised score is such that when all scores are put into a graph and age weighting applied (September births have an age advantage over August births), that all the results can be plotted into a normal distribution graph.
I don't know if it's different now compared to a few years ago but it used to be that the middle point was 200. That in mind, if your child gets 75% and on average so does many others then the standardised score will be about 200; however if your child gets 75% but most other score higher than that then your child will get <200 and likewise if most other children get below 75% your child will score >200.
The scores in a mock are never indicative of what may happen in the real tests because you have no control over how well your child's cohort get on. Neither of my children did mocks but I view mocks as serving two purposes (1) to be used to the exam environment and time management and (2) to see what needs improving on before the real test.
