Hi, are you starting at macrob next year?
I'm going to address your points and add some of my own;
-I don't think macrob is very competitive. Students tend to help each other out with school work. Sure, sacs and rankings remains at the back of everyones mind, but its not really an issue in my experience, anyway.
-Everyone is really nice. Macrob has the best student body, and there are so many student organised activities and clubs that it would take a long time to list them all. Go Naiads

-About teachers - macrob has good and bad teachers, same as any other public school. There are some bad teachers that I can think of off the top of my head, but overall the teachers are pretty good.
-And travel time - I'm really lucky to live about half an hour away, so maybe I'm not the best person to comment on this, but the majority of macrob and mhs students travel an hour or so to get to school too and the majority would say its worth it. You'll also make friends with people who take your line.
I don't take enviro science, but I know some people who take it, and they really enjoy it.
I'm really grateful that I get to go to macrob, and I really love it.
I had a lot typed out then it crashed and I had to retype everything btw, ffs
