Taken out of Barron’s Math Level 2 book:

Easy: The slope of a line perpendicular to the line whose equation is (x/3)-(y/4)=1 is
A. -3
B. -4/3
C. -3/4
D. 1/4
E. 4/3

Medium: The plane whose equation is 6x+5y+10z=30 forms a pyramid in the first octant with the coordinate planes. Its volume is
A. 15
B. 21
C. 30
D. 36
E. 45

Hard: If (x-7) divides ((x^3)-(3k^3)(x^2)-(13x)-7), then k=
A. 1.19
B. 1.34
C. 1.72
D. 4.63
E. 5.04

I would definitely recommend buying the Barron’s Math II book. It’s a lot harder than the actual test and kind of sobers you up. I took all 7 practice tests in the book and averaged around a 700 (scores improved just slightly after reading through the book,) but ended up scoring an 800 on the actual test.
