Actually, JMSS has many things such as basketball/cricket and tennis courts. They have a green screen. There are many fun things to do there such as robotics and it is just as good as any other select-entry school.
this thread is getting of topic,
We have a basketball ground but not a cricket and tennis court

where did you hear that?
Yeah we have a green screen but i think most schools have that

In terms of sport, most of our sport teams use the monash uni facilities so I think Pi is slightly inaccurate when he says the school doesn't have the physical resources other schools have ( it is more like, they have access to the resources they need but don't own them). Almost everything is done at monash uni, so yeah we don't own the resource but for instance, if you wanted to start a badminton club you could easily do it, just ask the school and they usually book the courts for the school team to use weekly.
That being said you can't use them at your own free will, so at lunch the only thing you will be using is the basketball grounds ( when it comes to sports that is )
There are sport teams, but not as many as other schools. Sports isn't a big deal like it is at MHS, but its still there.
BTW, ask this questions once you actually get into a circumstance where you need to decide lol
