Not only did I cross, I'm crossing back. And, I didn't finish my degree. I went to NCSU for 3 years in Civil, worked in Civil for several years doing design under a PE. Then, I crossed to Mechanical, new product design. I passed EIT and took PE in Mechanical 3 times. Waited about 12 more years and decided to take PE again. I knew I needed a review course and the only available for me was in Civil. Since I had been in Civil and had a desire to return to Civil, I convinced the board to let me sit for Civil exam. I passed. Would I have passed Mechanical 4th time? Don't know, but I'm looking forward to going back into Civil. In many ways, I think engineering is engineering. I have a good deal of valuable project management experience that can work in any discipline.
