It isn’t just the number of AP courses. Which ones matter.
AP courses in statistics, human geography, and environmental science look less impressive than calculus, US history, and chemistry, for example.
Skipping non-AP courses like precalculus, foreign language level 3 or 4, and physics to take AP courses in statistics, human geography, and environmental science also may not looks so good, and put you behind in actual preparation for college work.
