The premise is to combined property information + school information (geo data) + school rankings and provide it all together for people to help them figure out good places to live, raise a family, send their kids to school, etc
As someone who was not born in Australia sometimes we struggle to identify if a suburb is good for families, with good schools etc. I built this to help us figure this out as well as look for new suburbs out in the country side of the state.
A particular test has assertions that must be implemented correctly in order for them to pass.
By starting in red you gradually make your way towards green usually paving your thinking and potentially unlocking other tests.
I don't believe you must do this every time though.
