Here is an email you could write to your friend about this topic:
Hey, I've noticed you've been trying to get into this school for a while and I just wanted you to know a few things so you're not lost like I was the first day. First of all, this school offers so much in terms of extra curiculars. I myself am doing computer design and beginers HMTL, but they offer lots of thing that I think you'd like. I know you're a fan of sports which is cool because some of the facilities they offer are Soccer, Basketball, Badminton and there are a couple more, but I don't think you'd really be interested in it.
when writing an Email to your friend, you can use shortened language and personalized words that you otherwise wouldn't on a formal email. One of those words I used was "hey"
You can also personalize your email to that specific person, which I showed buy saying "and there are a couple more, but I don't think you'd really be interested in it."
