Look mate with the training that you say you have been doing you will pass no problems. Unless you cant take orders.

I went to ADSC thursday 21st and had the most brilliant time, there was four para's there including me, we all came 1st to 4th out of 32 recruits with times varying from 8.40-9.19 ...

The minimum.
1.5 mile in under 9.30 min,
2 mins 60 push-ups,
2 mins 60 sit-ups.

That's the requirements before you even go to selection centre. So it can only get better..

They're not big on chin-ups, but practice in the morning and night. You will get there in the end mate.
