Hi, I've got my ADSC coming up next week. I'm aiming to meet the requirements for the Parachute Reg, this is my first and only choice really. However I was told to have two other choices as a "fall-back", these were the Mercian Reg and third was the Royal Artillery - Light Gunner. With any of these choices will I have to do the TST test when I go? I'm shite at maths. Thanks.
