I am a 24 Year Old Chartered Accountant (Indian). I used a peculiar direct entry scheme for the qualification, which essentially means I do not have an undergraduate degree. The last time I learned any sort of intensive math was in 12th Grade (Commerce + Math). However, I am interested in becoming a mathematician, and have been teaching myself for some time now, although I would much rather get some formal training. Unfortunately for me, every Degree in Mathematics requires me to have studied Science in 12th Grade. At this point I am at something of an impasse. On the one hand, I am fond of mathematics and am more than willing to teach it to myself till I'm 70. On the other hand I know that to enter a career in Mathematics I will need formal education which seems beyond my reach. Is there anyway I can break into this field from where I am? I am more than willing to take any exams it might take to prove my knowledge. Is there any respectable university anywhere that will accept a student like me?
