<p>Does the high school offer a one year BC course for seniors who completed precalculus as juniors? That is what one year ahead in math students took when I was in high school (it was the only calculus course offered then).</p>

<p>No, unless there is really nothing better to do. Lots of students enter college having had only AB, or just precalculus, in high school. Also, given how many repeat first semester freshman calculus, many apparently did not learn all that much in AB in high school anyway. So she will not be “behind” with just AB (she will be ahead by a semester in math at most colleges).</p>
<p>Be aware that the first semester calculus course in the summer will run at double normal speed (since a summer session is typically about half as long as a regular semester), while a high school BC course that starts from where AB left off will run at half normal speed (taking a year to cover what is ordinarily second semester calculus in college).</p>
