🏫 What Colleges Prefer: AP vs. IB – The Expert Insights

What Do U.S. Colleges Think About AP & IB?

• AP is widely accepted across U.S. universities. Most colleges will award credit for high AP exam scores (3-5).
• IB is recognized globally and tends to be more highly regarded in international contexts. However, in the U.S., AP is often favored for college credit, especially in non-HL courses.
• Ivy League Schools like Harvard, MIT, and Stanford tend to value both, but they appreciate students who take the most challenging course load. If you’re in an area that offers both, choosing IB may show your ability to handle a more rigorous academic program.

Does MIT Prefer AP or IB?

MIT doesn’t show a strong preference but appreciates AP scores in subjects like math and science. For IB, HL courses (like math, science, or languages) are weighted heavily when evaluating candidates.

What Top Colleges Say About AP vs IB

• MIT & Stanford: No official preference, but rigor matters.
• Harvard & Yale: IB diploma is impressive, but AP is more common.
• Public Universities: AP is widely accepted; IB earns credit for HL courses.

💡 Example: Harvard awards up to 32 credits for high AP scores, while IB HL courses must score 6-7 for similar credit.
