Hello.
I think in all your moving sections around, I think you still need to move the Finite Geometric Series mini- section OUT OF Polynomial Factorization section. The FGS simply does not relate to Polynomials. I haven't taken the test yet, so make sure when you go to move that you remove the test questions if there are any.
Thank you.

As a teacher who uses Khan Academy heavily for my Algebra 2 class, I share this viewpoint.
Geometric series are wonderful, and I suppose the formula contains a piece that is basically a binomial times a monomial, so in a way they relate to polynomial factorization. However, the connection is loose at best, and they deserve proper context and introduction, which is absent in the polynomial factorization unit of Algebra 2.
Khan Academy courses don't introduce the basic ideas that build to the geometric series formula until their Precal course (last I checked) so why on earth are Geometric Series practice exercise dropped into Polynomial Factorization? It's beyond my comprehension.
I am left with the frustrating choice between stopping and teach everything leading up to Geometric Series so the students have a hope of understanding the practice, or skip it and have the Quiz 3 and Unit Test be a lot less useful because of the questions on the subject I didn't cover.
Why not just keep those practices with all the sequence/series stuff in Precal? Why not add a sequence/series unit at the end of Algebra 2? Just please don't leave those items in the polynomial factorization unit of Algebra 2.
Love the site. Thanks a bunch for it!
