>>13021422no it's different for everyone some people do pretty well through calc and diff eq and can't do linear algebra. Some people can't do diff eq but can do abstract linear algebra or topology.
The truth is, it's all easy and everyone is actually just moronic. There's no point where it becomes hard, just a point where it becomes boring, because it's not actually necessary for real life. At some point it becomes increasingly irritating to pay attention to except for some people who have mild autism. But it's ok, arbitrarily enriching ones mind is for the priveleged, and if you are not priveleged and instead have what you consider to be a 'real life', don't study math.
