Obligatory reminder that Brave has been caught doing nefarious things such as 1) injecting cryptocurrency affiliate links into your pages; 2) installing paid VPN software without consent; 3) injecting their own ads into pages; 4) scraping and reselling data; 5) their website taunts browsers that use Mozilla user-agents; 6) and more. With that sort of immoral development team, I wouldn't trust their browser or products.
I wish these courses would also provide the answer sheets or tell you where to find them. How am I supposed to check my work and verify my answers otherwise?
