Im a sophomore in IB at the moment, and i've heard a lot about ToK. I'm pretty excited about it, many of the older students say it changed the way they view things, and that our school's ToK teacher is exceptional. Apparently at the beginning of the first class of the year, the first thing the student's are asked is 'how do you know 2 plus 2 equals 4?'. And in the IB MYP, not all the kids are that motivated, but they're 'filtered out' before the diploma program. I attend a IB world school here in Canada and i live in an area with relatively high immigration rates, so there's a lot of competition since immigrants (like my parents) are obsessed with education.
