Yeah true. I don't know the scene in the schools but I have read a lot about how math education is pretty dismal, at least in the USA, depending on the teacher
Maybe theres a way for an app to help someone who does have a math aptitude to realize that they do and that math is fun and not a bunch of rote memorization of formulas
And repeat for like.... a bunch of other types of thought
But you're right, it is pretty broad, so maybe best to start with a specific field
There are apps like Brilliant that focus on math, so maybe that fills that niche, or maybe theres something that else could be added to it in terms of helping someone explore the raw thought processes involved
Maybe you could devise a test that, when completed, can detect where their natural strengths lie. I imagine such a test would be somewhat lengthy. That could easily be turned into an app and marketed.
