313d level 2 exemption exam questions
« on: May 12, 2015, 04:08:24 PM »
I just wrote the 313d level 2 exemption exam because I did my first block of schooling and didn't want to go back to school for level 2,  these were some of the questions that stick out in my mind from the exam that were not on any of the study guides I had used online.
