Fall '15 admission CSUS and CSUEB: Is it ok to sign the intent to enroll (ITE) for both?

[slaybee]

Lots of questions but I'm totally stressed and the wait is killing me....

I'm currently waiting to hear from Sac State and CSU East Bay for fall '15 admission into their BSN pre-licensure programs. I've already been provisionally/conditionally admitted to both schools. (I've also been accepted into CSULB's program but that's my back-up because I live in the bay area...though they did get back to me a helluva lot faster on my app status and admission)

The deadline for the intent to enroll for both schools is May 1st (June 1st for LB). From what I've read on this site I think I wont hear until the end of April or beginning of May from Sac State, and the very end of May from EB.

Is it possible to keep all of my options open by signing both (or 3 if they email me by LB's due date) ITE's? Could the other schools find out and withdraw my admission?

How many other people are waiting to hear from these schools?

I got a 90% on my teas, cum gpa 3.98 and pre-req gpa 4.00. No work experience, and I'm not bilingual or even able to scrape by with Spanish. What are my chances of getting in? I think im in the 80 point range but I dont have the files on my phone to properly calculate my points right now.

Seriously any form of advice would help. If I could get away wifh signing multiple ITEs my stress level would go way down
