I wouldn't say it's a waste a time, just that in tech industry people have a tendency to overrate "selling shovels in a gold rush" when they have about the same odds of success. ie. Making a successful game vs successful game engine

I've done a lot of research on this topic, the short answer to your question is https://artofproblemsolving.com/

But during my research I came across the idea of "Computational Math/Thinking" which throws away the entire concept of learning Math/Science in the normal order

Pre Algebra > Algebra I > Geometry > Algebra II > Trig > etc

It takes more of a real life problem solving approach, which I understand isn't exactly innovative in and of itself but prioritizes using the computer for the calculation part of math.

Of course the process of using a pencil and paper to calculate an equation in probably 90% of the work in traditional curriculum. When you outsource this tedious part to software (like you would in real life) that leaves room for setting up bigger problems that literally cannot be calculated by hand.

A similar situation is going on in the US.

Right now the most popular rapper (measured by streams)is Tekashi 6ix9ine, a controversial artist who raised concerns recently over being cheated out of the #1 Billboard Hot 100 spot.

It broke the record for most youtube views in a day (43.5 million) and also fastest to reach 100 million (71 Hours).

It also hasn't received ONE radio spin, for comparison every song above it has at least 20 million.

It also has been banned from every major Spotify playlist.

After questioning the credibility of the Hot 100 ranking methodologies multiple top artists have come to Billboards defense (Ariana Grande, Justin Bieber, etc.) even causing billboard itself to release a statement.

It's resulting in a Streisand effect of people wanting to see what's this song/artist that the institutions are trying so hard to suppress from the public.
