Going Back to Grad School I am seriously considering going back to graduate school for the PhD and I have two schools in mind. The problems I am facing are: age and I have no letters of recommendation. I do have a MS in Math and have been adjuncting since graduating in 1998. My question, what would be a good strategy for re-inserting myself into graduate school and be able to get funded. TIA.
One idea that could work is to try and do another masters in math somewhere that has a thesis requirement.  You can use this thesis to study a research problem that is currently being worked on by faculty at the schools that you want to get into.  

If you can't do a second masters, how about an independent study somewhere with a prof. that could agree to supervise you for a semester or two?
