if anyone has any tips that would be great thanks x

My advice is this;
You are going to spend a about a year researching,designing,prototyping,evaluating,repeatedly.
It will help a lot if you are passionate of what you choose, hence I would highly recommend you choose something you care about
Additionally, there is no rush to pick this instant. I took weeks to come up with my ideas and so did my entire class,In this time I would highly recommend asking everyone (friends,family,relatives,teachers,random people on the internet) what they think. Getting a lot of opinions really helped me figure out what I actually wanted to do, even if it had the side effect of making everyone annoyed with how much I talked of NEA ideas.
Furthermore you don't need your final idea for a long time, as long as you have a rough idea you can do most of your research and sketching then choose your final idea.So don't stress, and have a good think!
