@SamPoodle123 Both consortium and SPGS type of test, there are bespoken tutoring course, and you can guess how many West London prep students, whose parents specific target (obsessed) for SPGS school etc from age 4/7, will do it to maximize the chance.
I agree there is no need for those paid tutor really. If the child have time to practice those exam Questions with some help from parent, their chance will definitely to be higher, but again this will take time and effort.
And compared to some other Grammar 11+ test I have seen, these question are easier in the sense that I think myself can do well in these type of test unprepared, I also belive my colleagues, who failed miserably in the NVR test, will be OK at these kind of test even without prep. But still I'm not comfortable all we can be better than a bright 10 year old kids with proper preparation.
But again, the tests, as well as VR or NVR are just identifying certain type of thinking, for a 10 year old with tutor and practice will improve the chance. The difficulty or style of the paper has little correlation on the difficulty of actual getting the offer from the school. For the same level ability, with similar level of prep, the actual reliable difficulty level is application to offers ratio (note not application to admission).
Hence, in general London super selective grammar is harder than top selective private.If the entire cohort of the grammar students, stay to prepare and take the private 11+ exams, a lot of them will probably do better too.
