I hold an Electrical Engg degree currently and for the past few months I have been preparing for an entrance test for my Master's degree.Meanwhile my interest in mathematics has grown enormously and I find myself studying mathematics all the time (I have abandoned almost everything else). Although I was not exceptional(or anything close to it) in mathematics earlier it just seems like this is what i love the most. Can I become a mathematician now or is it too late? Please advice and thanks in advance.
