Got my MS degree last year, but still working on a paper with my advisor at the grad school. During the undergrad, I had dropped out my first major in the 3rd year, then started another major. I have Computer Science BS and Operations Research MS degrees, specialized on discrete event simulation. I got my BS and MS degrees with a mediocre 3.0 GPA. Because of my low GPA, it is almost impossible for me to be admitted into a reputable PhD program. I also cannot get a job because of my age and inexperience. I'm 29 years old, that's too old to start a PhD. What can I do? Do you have any advices?
