Depends on what you mean by getting it right.
In Australia, it varies a bit state to state, but it’s generally a straight contest of high school performance. There are a certain number of student slots available for any given degree, and those slots are filled by the applicants who scored the highest on their end of high school exams.
No interviews, no essays, purely numeric supply and demand. Prestigious/profitable subjects (law, medicine, etc) require high marks to get into, because applicants hugely outnumber the available slots; lower status degrees (education, social work, nursing, etc) require lower marks, due to lower numbers of applicants and/or more slots.
Of course, cashed-up parents try to get around this by paying for private tutoring etc. in order to maximise their kids’ grades in those high school exams. And there is a strong correlation between parental wealth and the quality of high school facilities, even in the public system. Remote Aboriginal schools are a lot less shiny than the ones in upper-middle-class suburbs, which are in turn massively underresourced relative to the posh private schools of the wealthy.
There is also a constant push by the right-wing political parties to more explicitly break the system (e.g. reserving some positions for underperformng students whose parents are willing to pay huge up-front fees). Those tend to draw vigorous objections from the general electorate, though.
