What IB Maths SL grade is equivillent to AP calculus AB level 4 OR 5.?

There's no direct, universally accepted equivalence between IB Math SL grades and AP Calculus AB scores. The courses cover different material and are assessed differently. However, a general comparison can be made:

* IB Math SL Grade 7: This is generally considered to be comparable to a strong performance in AP Calculus AB, potentially a 4 or 5, but it covers a broader range of mathematical topics beyond just calculus.

* IB Math SL Grade 6: This could correspond to an AP Calculus AB score of 4, depending on the student's specific strengths and weaknesses.

* IB Math SL Grade 5: This might be comparable to a 3 on the AP Calculus AB exam, though again, it's not a precise equivalence. A 5 on the AP exam suggests a stronger understanding of calculus than a 5 in IB Math SL, which is a broader math course.

It's crucial to remember that these are rough estimations. Universities will individually assess the qualifications presented by applicants. They'll look at the overall academic profile, not just a single grade or score.
