What did anyone expect? really, many children especially in the Andes suffer from lead intoxication from mining, fruits and vegetables for export are premium quality while the ones for local consumption are bathed in pesticides and other chemicals, kids in the amazon suffer from parasites and other illnesses, tons of regions have malnutrition... etc.

Then there's the fact that Peru is massive (compared to Europe) and most of it lacks internet connectivity, only just recently Starlink started giving newer phones SMS capabilities outside of coverage, but that's as far as it'll go and only for modern expensive phones.

Those kids are not going to open a laptop and have a good time attempting to learn something (if they can even reach the internet), I myself have ADHD and it took me so long to even search and discover khan academy (let's not even begin with how much worse sites like Khan Academy are when you don't have the primary instructor, giving said lessons), add in low energy/inability to concentrate or want to do academic work with memory issues due to intoxication and or malnutrition and... yeah, good luck with that.

There is high amount of talent in Peru, you can tell because there's government programs to give gifted students from public schools free scholarship to private universities and they all end up top of their class, the hardest university to enter into in Peru happens to be a public university too (national university of engineering), it's exam is pretty fucking hard for someone who just graduated high school and even then the vast majority of students who enter come from poor backgrounds.
