There are many situations where school is not the best place to learn things, life could teach you better, but unfortunately people study at school a lot better because there is an exam that you get a result from whereas in life there is no result in grades but real life consequences so they do not study as hard.

If you want to learn more about crypto, from software to finance there are many classes on online worlds, from free youtube videos to expensive online classes there are many things that you could use to learn more stuff, if you really study hard and actually give your attention to it and learn it, you could definitely get better at it, but studying at school, either from financial part or software part, you will only learn a bit of it, not the whole deal, things that are resembling crypto but not crypto itself and that is why online is better.
