As an ex recruiter I would still say First Impressions count. We didnt expect suits but it does show personnel pride. I have seen people enlist in tracksuits. Dress smart, relax and give it your best shot.
As a Recruiter pay heed to the following "you dont get a second chance at making a first impression" trousers and polo should would be ok ,then you can dress up in suit for RSC and Enlistment.It shows you can look smart and have standards, but as always its up to you!
Agree with a lot of the posts on here at BARB test stage smart and casual, nothing offensive (slogans) but as said first impressions last and even though Recruiters are getting on a bit will remember. Just remember to practice that bARB booklet plenty of times prior to you going in for your test, it looks easy but once under a bit of pressure then can be harder than you think.
You need to get at least Entry Level 2 which is equated to that of a 14 year old level at school. Its a case of using a computer, listening and working out the answers. If you were above an E in your GCSE I wouldnt worry too much. Whilst I was in Recruiting my daughter had a go when she was 10 and passed easy enough. Concentrate more on the BARB booklet to get a decent score.
