I raised my score by 200-300 points in each category by spending some time with one of those study prep books with the example tests. This saved me about $8k / semester due to ‘merit’ based scholarships + honors program (my university publishes the SAT/grade cutoffs for each). Honestly I would be surprised if it was possible to create a test that was both impossible to improve with practice and actually measured anything at all.
