Not sure I get what you are wanting to do.
You want to use the 368 to transfer to the reserves and attend college while serving in the reserves to eventually get a commission to go back into the Active Army or Reserves? I don't see why you couldn't do this.
Or, you want to use the 368 to leave the active duty and not join the reserves until you have completed school and can then get a commission in the Reserves or Active Army? I don't see either side as willing to accept this option.
Form just states a transfer between reserves and regular service. Sounds like it would work both ways to me. Reserve > Active = Active > Reserve
Sounds like you need a reserve recruiter.
