Advice for new PGCE mathematics student

Recently I offered some advice to an incoming PGCE secondary mathematics student - someone just starting out but who needs to (a) complete the PGCE and (b) be employable a year from now. I'd like to say "Recently I was asked for" but it was totally unsolicited rambling - but happily gratefully received. Anyway, here it is:

• Do you read Nrich? You should. Also Plus, iSquared.
• Have you joined the National Centre for Excellence in the Teaching of Mathematics (NCETM) portal/mailing list? You should.
• The IMA has recently launched a Chartered Status for maths teachers – CMathTeach – which you may like to be aware of.
• You could also think about volunteering to help out with local Royal Institution mathematics masterclasses, which are apparently a lot of fun and I imagine a good way to show you are beyond the average PGCE graduate.

I suppose I should have added join Twitter. Any other advice?
