It's different than learning if some of the prep is around test-taking strategies oriented towards the type of questions on a test.
So for this problem you could be good at multiplication or test taking to get it right:
5231 * 8243 =
A) 45,768,329
B) 43,119,133
C) 4,311,931
D) 43,911,332

You can also be trained in specific heuristics for certain types of tests without having the ability discover those heuristics yourself.
