Some people just won't ever be good at math. There are people who have basically no visual intuition and can't predict what an object will look like when rotated in 3 dimensions. It may be possible to practice this but someone who does poorly at this untrained is unlikely to ever reach even median level ability. There are techniques you can learn to perform this task in a multiple choice test situation but they don't train your brain to be better at visualizing 3d rotations at all.
This is not to say that object rotation is a proxy for mathematical ability, but just a demonstration that there are cognitive tasks which people vary widely in ability on when untrained and which we don't have an effective way to train, at least at an arbitrary age. Lots of Math seem to be this way.
