Hello,
this is my first post on mathoverflow so excuse me if this is not the right kind of question.
My situation is the following, without delving into reasons and *should've*s *would've*s I got kicked out of university before starting my final year of an undergraduate mathematics degree. The problem is that this has nothing to do with me not being able to do well in maths or having lost passion for it. Therefore, I would like to continue my studies into the subject. I was wondering if anyone knew someone in a similar situation and could give me some advice on how to go about it.
Obviously, I can still get books and find structured courses on-line but I am afraid that this might be very inefficient as I have no one to show my workings on the problems. I can occasionally post a slightly more interesting question somewhere on the internet and without a doubt I would get the answers that I seek but what about all of the exercises that you have to go through in order to learn new subjects? I would never know if I got them right, my expression will end up underdeveloped and arguably I will pick up bad habits on the way. And it would be really difficult to judge my own progress and know if I actually understand the subject that I learn. Plus I would end up having lots of holes in my knowledge without someone questioning my every step while I'm studying.
Also, this is probably case by case and even depends on local laws (I'm currently in UK and was studying here) but do you know what happens in a situation like this? Grad schools probably won't even consider me, while going after a bachelors degree might mean having to take a lot of known subjects for a second time.
