Real quick though, if you are on the HSCP (for navy) the active duty during dental school wont count. I know the loans for dental school wouldn't be eligible for the PSLF because they are not "active", but undergrad loans wouldn't count either. This is because, apparently, your status while in dental school is something like being in "A school." This is probably not applicable for most people, but this is what I have discovered.Yes, all active duty years will count. May as we’ll keep up on the documentation and all that just incase you stick around the whole 10 years...or if you separate you could look for a govt job to fulfill the remaining years
