SMP Cadet and ARNG Tuition Waiver

So basically, I am in the ARNG as an 09R and am trying to contract with ROTC. The problem is, I’m getting held up by DODMERB for a waiver so that process is being delayed. My question though,as an 09R, is could it possible for me to receive my tuition waiver before I contract with ROTC? I’ve heard conflicting things from Cadre, my recruiter, and others.
