What exactly is NCS and is it actually useful

I did it, was 5 days of like activities, like kayaking, climbing waterfalls and other stuff it was fun, also had like a week of volunteering after. honest opinions is I only recommend if you're doing it with friends, because most people come with their friends and have like little groups , or atleast that is how it was for me. Now about the ucas applications, yes I did put it on mine because ive applied this year, however when putting it on your application you need to mention like what skills it brought you, I put leadership because I conveyed leadership in some of the group activities. Honest opinion is if you're going with friends and have free time in the summer holidays? why not do it its fun you feel independent and get to rack up skills like leadership and volunteering.

uhh ahah just some of the other people on the wave I went on ahaha some girl chucked a chair at my friend, it was funny tbf. but other than that it was pretty enjoyable ( however we had a hike walking for hours ON ONE OF THE HOTTEST DAYS in the UK, I hated that but we got through it, got to have a nice view though )
