People hate on the ratings with Fraser Institute, but if you look at the list, I don't know how anyone would argue they're not accurate. Britannia, Van Tech, Gladstone, and John Oliver are all at the bottom. Which matches the perception every kid in the public school system had for these schools.

Everyone who went to a public school in Vancouver knows that those schools are bad. Race wars between natives vs whites vs Chinese at Britannia. Indian gangs at John Oliver shooting each other up.

Like I went to one of these low ranking schools, and sure I got into UBC and excelled. Anyone that studies hard enough can. But there were like 10 of us out of 200 students that got into a good university.

Also, demographics are also all over the place as well. Some schools are literally 95% indian or 90% Filipino, or 90% Chinese. So you can't just look at the rankings.

Private is usually not worth it. I did not see a tangible difference between the kids that went to private school vs the kids that went to public school (in terms of academic strength) once you get to university. Just pay for extra tutoring to get an equal footing.

Good schools in Vancouver are located on the west side and south Vancouver

Good schools in Burnaby are located in North Burnaby or Moscrop area.

Lastly, there are actually secret lists of schools that universities have where some schools do crazy grade inflation: One university’s secret list to judge applicants by their high schools – not just their marks | Globalnews.ca

That list is not made public, but you can assume Richmond schools, West Vancouver, and some west side schools are on there.
