Is there a simple strategy for jumbled letter questions?

[Beck_mum]

My daughter (and I), either just get these or struggle for ages with them. Given that she's doing a GL test where they have 7 minutes or so for each section (I think), I wondered if there were any quick strategies for when the answer isn't obvious? e.g. are certain letters most likely to come first, others most likely to come last (I imagine e, s, er, es etc), and others most likely to come together (oo, oa, ee, ck, etc). If these rules/strategies exist please could someone enlighten me!
Thanks so much in advance.
