advise on starting a phd in mathematics ? Any idea on difficulty to expect on

study material,finance etc...? Anything that can help.Thank you all for your time.

If you are really good then you can look for an academic jobIf you are so so then you can work in finance or designing weapons for the military (figure out the parabols made by the missiles etc.)Just be prepared for several years of study.

if you really like math you should do something with statistics and computers. If you are good at it you can make bank working for a hedge fund. my calc 2 professor taught alot of students who didn't even finish their PhD's before they got offered 100,000 $ salaries
