I want to ask about EPGY OE (Open Enrollment)

Background: In another thread
http://giftedissues.davidsongifted..../all/Debating_home_school_vs_virtua.html
I say I want to quit our k12.com free public charter virtual school, and go to pure home schooling. But I need to convince DW. Mainly I need to find convincingly solid course materials for Mathematics and English/ELA (and the rest we'll improvise)? We need it for DS8(will be grade 3, but ready for Algebra I, and grade 4 English/ELA), and DD5(will be grade K, has been reading for 2 years and can do a bit of writing and arithmetic, purely self taught).

So I see at
http://epgy.stanford.edu/for-parents/epgy-open-enrollment/courses
that EPGY OE covers Mathematics and English/ELA K-7, plus "Beginning Algebra", in a purely online format. It is $135 per 10 months, so the price is fine for our cost conscious budget.

Is this price per student?
When we look at the Registration Form page
http://epgy.stanford.edu/for-parents/epgy-open-enrollment/register
we see there is a choice to join an existing group, or create a new group (which could just be our family).
Any thoughts on choosing or creating a group?

As to the course content, how comprehensive is it?
It is purely online, right?
What kind of instruction does it include?
What is necessary/desirable to supplement it with?
For math, do you just use you own blank paper to write on, as needed to solve online problems?
For English/ELA:
What do you do about basic handwriting practice?
What do you do about writing/composition practice?
What about reading? Presumably you have to buy/borrow books to read, but do they have suggested reading lists, and do they have online content related to that reading?

Generally, in what ways does EPGY OE fall short of being a complete Mathematics and English/ELA curriculum for homeschoolers?

It says the Language Arts and Writing course assumes the student read at least at grade 2 level. I don't know what level this is, but surely DD5, self taught and reading for 2 almost years, would be at that level, right?

DS8 needs a good Algebra I course. He found k12.com prealgebra very easy, but he is not yet fluent in solving equations and algebraic manipulation (past the most basic kinds) and he needs instruction, not just problem solving. Is EPGY a good foundation before moving on to AoPS?
