Why does that image only have the sun and the rebel from Canadian media? Both are given more credibility than they deserve, the rebel in particular has history, bunch of white supremacists and alt right personalities were or are still involved, publication absolutely stokes hate and fear.
Edit: I'm still at a loss, why those? The Globe and Mail, McLean's, The Toronto Star, National Post, CBC all have better reputations domestically (though natpost and the sun are a circle these days and most print media is owned by American Hedge Funds so...), far more likely to actually get the news instead of opinion masquerading as news in one of those.
Not the person you replied to but for interest, It was 25 hard capped in grade school only because of the program I went through back years ago, though looking now 25-30 is petty consistent in that region as of last year. Highschool was larger, maybe 30, less once going into upper year courses, literally 8 of us took comp sci and that was combined gr11 and 12
Ontario, Canada for reference. 20 seemed low to me too tbh, but not out of the realm of possibility.
