a month before Main Board

Hi guys,

What preparation would you do for the month leading up to Main Board. I'm OK on current affairs, my mental arithmetic, well I don't know where to start so will just keep practising SDT, my fitness is OK, just my sit ups need some work, I can also do about 55-60 press ups.

I did my briefing quite a while ago, so the incubation period between that and MB is a good 7 months.

..what kind of things do you recommend you do a month prior to MB?
I've heard that bicycle crunches are a good thing for your abs (the sit-up muscles, I understand). Why not chuck a few of those in to your routine, as well as sit-ups.
And, of course, best of luck!!!
