I applied last year for VS and was progressed to VI.I completed a VS at Clydes 3 years ago and there was one graduate / career changer who was a fair bit older, the rest were current students. Not sure if it has changed since then! The graduate was one of the few who did receive a tc though
This year I applied without noticing the policy and got a fairly swift "you are not eligible" PFO.
So i think it's a brand new policy for this year.
