exactly.
In my sons case on his 2nd SAT he spent all his time on verbal section. He scored lower on the math section than the 1st time but he was not concentrating on that as he already had a decent score on that section.
The next time he concentrated on the math and improved that score.
Before each exam he took several practice tests.
His prep tutor was able to explain how the test would be constructed. he would show him sample questions and tell him; there will be two of these, three of those, etc.
Really took the mystery out of it.
It not only helped his ROTC application (I think) , as he got a 3yr AD, it helped get him a very sizable merit scholarship to use his freshman year.
