My daughter just finished her freshman year. She had Trig/ calculus A this year but had the same basic math track before as your son. In her case the geometry was easier than the Algebra 2 though she got A's in both. I can't imagine there is an option to skip Algebra 2. At this point just my opinion I would take MAP scores with a grain of salt considering high school is more demanding than grade or middle schools. My daughter did a non credit engineering class last summer ands had no interest in taking it in high school. She took band and to be quite there is no doubt it would easier than engineering espicially since she took AP Human Geography which was the hardest class she took.
