CSS for 2 students

We completed the CSS for tw2 in October for an EA school. Now we need to submit to the other schools and I’ve read here that we can’t update it all, even though we have more accurate info now, true? Our estimate for 2015 looks like it
was off by $2,000, but who really knows what the future holds? For tw1, do we fill out a brand new css form with the most up to date info or just copy what we put on the Oct form for tw2?

And for fafsa, I only need 1 pin, right, and each tw gets their own?

Thanks for any advice - the kids worked so hard on their apps and merit scholarships, i don’t want to mess things up now!

yes

Each kiddo needs their own Profile. Yes, you can do different and up to date info for the new schools. The 2014 income is the most important one.

Yest for tw1 you do a Profile with the current info.

Yes…one parent PIN…and each kiddo needs one as well for the FAFSA.
