I have a Bachelor's of Science in Physics from the University of Maine. While I was there I tutored physics for 4 years to hundreds of students. I currently work at ETS and make the physics and astronomy questions that go on the CAST test for California. For those unfamiliar, the CAST is the end of year state exam administered to middle school and high school students. I have also developed for the TCAP, STAAR, and HiSET exams.
