Have you started your A2's early? We have, so I'm just focussing on the new work. If you haven't keep yourself busy, play sport, play a musical instrument, teach yourself mandarin, just do ANYTHING that means you don't have time to think about it. That's my tactic. I've found netball and football are the only things that truly distract me, you need to find something that you can absorb yourself in.
Hope this helps.
