It's similar in the US, where we have the SAT IQ test and the GRE (SAT repeat plus basic knowledge test in a subject area).
Neither has the sort of deep knowledge you'd see in a US Graduate Degree "qualifying exam" which tests depth of understanding of undergraduate material (for which many students use remedial graduate school classes to prepare)
This is broadly true, but qualifying exams can be wildly different even within faculties, let alone across schools - enough so that I can't imagine a meaningful comparison of "results". They are also often pass/fail.
