Only the last two units in BC are new content, which they are starting just now. Interestingly, even though BC was a repeat the first semester she did better in AB, different teacher who she liked better.

Our school requires AB first, so they "rush" thru the AB material in 4-6 weeks, so BC new material can be taught over a longer period/at a slower pace and finish well before the AP test so plenty of time for review/test prep

YUP! If you get thru BC (via AB in 11th and BC in 12th) that is considered rigorous enough for almost any college. Most colleges prefer you take Calc 3 + at their actual university.
In reality, having your first calc course in 11th grade is TWO YEARS ahead of normal. Your kid is on a rigorous path. And if your kid is only on the Precalc in Junior year, I wouldn't recommend BC senior year unless math is very easy for them. My kid did AB then BC and BC (after the first 4-5 weeks of AB review) was a challenge---first time they ever didn't have a 99%+ in math since K. Calc 2 is a hard course, it's often a weed out course at college. So I'm glad my kid did AB first, learned the concepts and didn't try to plow thru BC as their first calculus course in 11th grade.

They are at a rigorous college in engineering and did calc 3 & Calc 4 (LinAlg/Diff Eq) and earned A-/A in both. So they were well prepared.

My kid did AB in 11th, and BC and Stats in 12th. BC is Calc 1 and Calc 2. AB is Calc 1.

Our district requires you to do AB first. That means the kids do extremely well in BC. For over 10+ years, the BC students (50-60 each year) earn all 4/5 (there has only been two scores of 3 in over 10+ years) and in actuality, 90%+ earn 5s. That's impressive.
Much more important for kids to fully learn the material and build a strong foundation in calculus than to rush thru it.
Also, even if your HS offers Multivariable calc (to take in senior year), unless it's thru DE, there is no way for your kid to get college credit, so they will be retaking Calc 3 wherever they attend. My kid (who got 5s on both AB and BC) is at a T30 college and 40% of their Calc 3 class freshman year was kids who already had MVC but had no official College credit for it, so had to retake it.

We have heard that these classes may be redundant but child is worried that moving directly into BC after pre-calculus may be very difficult - particularly given that they are taking a host of other AP classes at the same time.

If you are targeting T25, this is the least of your worries. If you are targeting below that level, they don't really care. Focus on rigor, GPA and getting a high SAT.

That is exactly what our school district encourages/requires. Kids go from Pre-Calc to AP Calc AB and then onto BC. The first 4-5 weeks of BC are a review, done at a fast pace since it's basically Calc 1 at college (AB) and then BC is Calc 2. The teacher can cover it at a fast pace because it is assumed everyone had AB last year.

I like it, because it helps build a strong foundation in Calculus. BC is a hard course (calc 2 is known to be a killer course for engineering) so much better to do well and actually learn it

Our high school requires AB and then BC . However, they do give approval for kids who are recommended to do both at the same time for those they know can handle it. They just don’t advertise it that way and bend for exceptional students.
