Hi, you’re going to have to be able to play three sports. However, my strong sport was football and I didn’t have much else. However, my school were happy help provide facilities and support on training me for badminton and I did tennis by myself (I went to a club out of school but I wasn’t very good!) I still managed okay. So although you can still do just fine having a strong sport you need to be able to do decent in others for the NEA - hope that helps!
