I'm a undergrad in a top-10 college in the US. I'll have a double major in computer science and math, but I've been focusing mostly on computer science (mainly because of job prospects), and all my research has also been in computer science. I took just enough math to get a second major, but my grades are still quite decent. But now I'm feeling I like math more, and I'm considering pursuing a Master's/PhD in math.
What would be your recommendations? I'm pretty sure I'll have to apply for a Master's first, to strengthen my background and get some research experience. I looked at some programs in the US, UK, and Germany, but I'm really not sure which would be right for me. Any recommendations on the programs would be welcome!
