Going from a low GPA math degree to a 100k salary as a SWE in 3 months might be a bit ambitious. I have 1st class honours and 9 years experience. I'm not up to that yet. Admittedly I'm in a small city in New Zealand where they pay is not great. That said you should be able to get into software engineering relatively easily. I'd suggest reading Ultralearning: Master Hard Skills, Outsmart the Competition, and Accelerate Your Career Book by Scott H. Young. It outlines a pattern for this kind of self education. Try to work as much as you can with people in the industry. Internships are a great way to get contacts. Anything you can do to meet people in the industry will help.
