shouldn't the QA be A???
They stated x and y are both negative numbers..
even if you take a fractional value for 1st statment answer still comes out no. ex (-5/2 * -14)
where is the source from? thanks

IMO A
3^-(x+y)/ 3^-(x-y)= 3^-x-y/3^-x+y
1. when x=2 it's 3^-2-y * 3^-2+y = 3^-4 as answer.
what is QA?

Stament one just repeats it self and values of x will vary
Statement 2 says (x-1)*=x-2
which implies (x-1)*= (x-1)((x-1)-1) =>
(X-1)(x-2)=(x-2)=> x^2-3x+2=x-2 and from here it's just solving quad equations. so hence B answer should be x=2

x, y, and z are postivie INTEGERS is y >x? 1. Y^2= xz For example, if y=3, y^2 =9. The only intergers that work for x and z are either 3x3 or 1x9 or 9x1. Therefore Insufficient 2. z-x>0 from this we know z>X but we have no information about Y so Insuffient From 1+2 we know z is greater than x and to...

Not sure if my method is correct but, considering -2,-3 is the center and point 4,-3 is outside of the circle, and knowing that radius r is an integer, there are 5 spaces between -2,0 and 3,0 therefore raidus is 5.

you might want to consider MGMAT series of 8, which breaks down, math and verbal by sections. MGMAT sentence correction is gold. Also I think OG series are essential to perform well on the gmats.

Pratice more on your timing. Also, Did you have any repeat questions during math that you already knew the answer to? This might be the case, if you didn't have timing issues on the practice tests...
