It's hard to put into words. We were going to send our girls to LJBC, it's walkable and people I knew were happy with their kids going there. I have met lots of South Africans over the years and they are lovely. However, I find the religious ones a bit strange and when I went to LJBC to look around and attend the open evening I just got an odd feeling about them and how they approached religion. I'm not saying they provide a bad education or pastoral care, far from it but it just didn't sit right with me. If it feels right for you then go with it, I'm a firm believer in gut feelings.
