Guilty as charged on the pre-judging thing.
my apologies. It just sounds so much like a private school :-) And being uni-sex as well, couldn't see how it would be a state school.
Or is that also a misnomer, and you do have females ?

However that being the case - major kudos to you, you are doing extremely well on a tight budget :-)
No offence intended :-)

Some great projects too.
