Ryan C. Cahalan

GT Physical Volcanology PhD Student

3/13/15 I passed comprehensive exams!!!!

After months of studying, practicing, and writing, I finally passed comprehensive exams. For those who don’t know about comps, at Georgia Tech we are required to write a 35-page proposal, followed ab an eight hour written exam and a three hour oral exam. If you pass, you become a PhD candidate and are permitted to continue on with your research at Tech. If you fail, you are asked to enter an accelerated Master’s program and leave the school.

Well, I passed, so onward and upward!!!
