just to put in my two cents: without wanting to degrade MHS in any way, i do agree with someone above who was advocating private schools. I would also tend to agree with clanyx in his (albeit very passionate) statements about rote learning. although i didn't attend MHS, i have friends that did, and the 'top 3% rule' would seem to indicate that the reason you get good results (although not the best) is largely due to your high level of selectivity.
As a result, i would argue that good results are more a result of the student cohort, rather than reflecting on the nature of the school and it's ability to teach. for example, the school i attended is not selective in any way, and yet had an incredible ENTER average of about 93... this, i feel, is indicative of a great school, rather than selectivity
that said, i would by all means encourage people to go to MHS as i'm sure it's a great learning environment in terms of competition, diligence, willingness to learn, etc.
