Hey, well:
1. I would feel REALLY miserable.
2. My parents would feel absolutely rubbish and probably wouldn't be as enthusiastic for a few weeks.
3. " " as if they wasted so much money on tuition and preparations. (I know I'm learning something, but still)
4. I would do miserable for the rest of this year and a little even next year,
5. I would be very pissed if my classmates got in when I know for a fact I prepare and study WAY more than them. (2 hours weekdays, 6 hours weekends [x hours EVERY day]
1. I guess you have to look at it from both sides. Of course 'not getting into MHS' will make you miserable but you just have to take it within your stride. Life goes on and really you just try to take on as many opportunities as possible
2. Selective Schools and Parents generally don't mix well together but they should know how the system works (3% rule etc.) and whether actually going to MHS is the right option too. A parent's worse nightmare isn't about their son/daughter making it into a selective school (does go on for a few weeks but it dies off quickly).
3. Again not a parent's nightmare and although doing tuition for MHS costs money, you do pick up good techniques which can be applied to other study areas so it's not exactly a 'waste of money.'
4. Depends on how you look at the situation but being miserable about the exam won't extend for that long. My friends and I applied for MHS/Mac.Rob/JMSS and when we all look back on it we don't really care too much about where we ended up.. some were sad but used that as motivation and eventually the hard work pays off
5. Personally I would agree with you on this one. When I was in Year 8 we all had an idea on who would get in but one of my friends who was a shoe in didn't get in whilst the 'slacker' got in... however there is always the year after and those are easier to get in if you're a sporty player (or want to apply for JMSS, EBSS etc.)
And looking at it from another perspective... I got accepted into MHS as well when I was in Year 8 and wanted to go (before moving to JMSS eventually) but parents said no due to private reasons but in the end I don't regret a single decision because Year 9 at my old school was probably one of the best years for me
