Looking to join the RAF

Hi I am interested in joining the RAF in intelligence or communications

I am 17, recently got a qualification in car mechanics, and currently studying carpentry

I was wondering would it be better for me to change my course to level 2 IT, as they would help me more with the roles I am interested in?

I have always loved car mechanics and carpentry, because now you have to do 2 years at college I decided to go for both, first year mechanics, second year woodwork.

I was just after a bit of advice if anyone has joined the RAF, in communications or intelligence and have any advice on initial training, specialist training or advice in general

I been boxing for a few years now, and love running, I run daily, in the last 3 weeks I have got my 1.5 mile run from 15 minutes to 12.33

Any advice would be appreciated

Thank you -Dan
