Aim at vs. Aim for

[Svedankae]

Hey everybody,

just wondering if there is a rule when to use either of the above?

Doesn't one say

to aim for success?

However the Manhattan GMAT SC book only features "to aim at" in their idiom list... Does that mean "aim for" is a no go?

Thanks

aim at + "a target" or "someone"

aim for "something"
