<p>u remember some of the math questions? i think i had the exact test as you because i had back to back math sections followed by back to back cr sections. and sec 5 was not experimental because sec 6 was. the first section had 25, 23, 24, 19 respectively and the questions have to add up to 57. 25+23+19=57.</p>
<p>the one for 81:
they gave u what c^d was equal to
then u had to write it as d^c for the answer
another possible answer for this is 256. they both work.</p>
