This is my first post here so I hope this is the right place to ask about this.
I am a 22 year old math fanatic in Sweden and have been put in the awkward position of having self-studied quite serious ''real math'' for about a year, and it has resulted from this that my university courses feel like a complete waste of time and that they actually damage my productivity, due to them being so easy, boring and not helping in moving me towards research I want to do. What's more the staff apparently doesn't want to talk to me at all and have consistently ignored my emails and seem to not be able to answer what I thought to be rather standard questions (eg. whether I could find some shortcuts for learning some Lie theory or homological algebra without having to read tons of exposition beforehand). They won't offer me any sort of deal and I feel completely alienated and invisible, I am not appreciated for having some special talent (particularly being really comfortable with abstract phenomena), but am instead treated as a burden. I am reading Bourbaki and Dieudonné's Éléments d'analyse and believe I am very well suited to Grothendieck-esque style, would like to work in the intersections of AG and (geometric) analysis.
Bearing this background in mind, my question is: Do I have any options for moving towards research other than continuing at my university or doing another standard undergraduate program? I have no interest in taking standardized courses which are not suited to my needs, and I mainly want to be somewhere where I can just talk math and get a view into what sort of research is done. My dream would obviously be something like the école normale supérieure but again they require that one has studied at least two years in such an undergraduate program. I would also love to have some sort of mentor, something like a PHD supervisor who I could just talk to. Do I have any real options or do I have to suffer through this for several years? Any advice on this is appreciated, I am quite desperate.
In the real world, saying that you have a special talent is equivalent to stating, in math, that you have a result. You need a proof. Flawed as it may be, a standardized university curriculum is proof enough to show that you have mastered the basics of a field and are ready to dive into the more complex and interesting stuff.
If the courses are boring and simple, just give the exams: if you know the stuff they should be easy for you to give. Then, you can use the time to study ahead for the more advanced exams. Put in enough work and you may be able to graduate ahead of time.
If you are as smart and determined as you say, professors will notice and you will have no problem in entering a graduate program; sadly, professors receive countless emails about self-proclaimed geniuses and whatnot. Prove your worth by working hard also on the stuff you find boring; that's how you grow.
