Accept the VS you have and in the meantime politely request for the second one to be moved to summer. If you get the vac scheme and they move it everything is fine. If you get it but they cant move it choose which scheme suits you.what would you suggest if I have an offer for a vac scheme that expires soon, but I'm still waiting to hear back from an AC. I do suspect that I haven't gotten a place at the second vac scheme as I think lots of offers have gone out, would it just be safer to accept this first one while I can? Also should I ask if I could move the second one to summer now, or wait and see if I get a place first? thank you!
