<p>I thought this test was pretty hard and Math 2 was so easy and I studied for this and didn’t study for Math 2. It could be due to the fact that I have only gotten halfway through a physic course, but the questions were different on this test from questions n PR/Barrons. What was the answer to question 71 about two currents traveling in directions with arrows. I put II and IV (choice B I think).</p>
