Math GRE

[Bubu]

If I remember correctly (8yrs ago - thins could be very different now) the math GRE is one of the easier subject tests. You need to know some basic results from different maths courses (beyond calculus, eg groups,
number theory, algebra - nothing too fancy though). The scores
tend to be skewed to the higher end (kinda like the math GRE section). You should at least look at some tests to see what material you need to polish on. A high score will not help too much, but a low score could hurt.
