<p>I don't think you can cancel after seeing the score.</p>
<p>For lsinxl, I'm pretty positive it's pi, because you see the up and down squiggle of the normal sinx becomes two even humps above the x-axis. I also checked for if x=0, pi, or 2pi, they all equal 0.</p>
<p>This test screwed me over... I was so pumped and raced through the first 25 questions. But those final 10, OUCH! I omitted the last 4. -10.</p>
<p>I took it with the US Ambassador's son though :P I realized it when I saw him and his father on the news earlier today (no joke). We were like 4 guys taking the subject tests.</p>
