I am Computer science student so pardon me if I am asking this in a wrong place!
My inspiration of learning maths is mainly due to algorithms and its feels to me that without mathematics I am not justifying my computer science degree, I am trying to work on my rusty math since last two years but until now I am not much confident enough the main problem that I am facing is that I no matter whatever I do I am making silly mistakes, I will be presenting a college level maths entrance exams next year, and am preparing for this for two years; but now there is a feeling that I might lack ingenuity, which is required to be able to crack any competitive exam. So, is there any way to develop mathematical thinking? Does a mathematician usually/(at some part of their life) follow any exercise to concentrate?
I would also mention that I am almost alone in my home and I am rather compelled to learn maths all my own. But is this even possible? I have taken some correspondence classes and I am trying with all my efforts but is it really possible to learn on my own? Please help me!
