What is the IB program? I don't think I've heard of it.
When I was in school, the only time we had homeroom was when there was something weird going on like testing or something. I never had study hall either, although I probably could have chosen to take it but I took art and science classes instead.
IB is an international school program. It's similar to the American AP system in that someone taking AP history in California takes the same curriculum and test as someone taking it in Oklahoma. IB is just more international, so a kid in England can be taking the same IB Psychology course as a kid in France, as a kid in Saudi Arabia, as Canada.
The difference is that in your IB class you are not just assesed by writing an exam at the end of the year. You also had to do things called "internal assessments" such as writing a research paper. These are then graded by your teacher, and a random sample from your class is selected, and those research papers are then sent to say Japan to be graded by IB psychology teachers there. Your exams are also graded by teachers from around the world.
IB diploma candidates are usually in their last two years of high school (or the equivalent in their country). The courses are equivalent to university course level. Unlike AP, you chose 6 courses to complete over 2 years. 3 at the standard level, 3 at the higher level. The difference is that the higher level courses last two years and cover more content. You must chose one course from each of the 6 catagories: Your native language, a second language, a social studies course, a math course, a science course, and an art course. Some students can take a second science course instead of an art course. In addition to completing these 6 courses, IB diploma candidates must also take TOK (theory of knowledge) which is a philosophy course that explores where knowledge comes from. You do projects in that class and are also required to write an Extended Essay (a 4,000 word essay on a topic of your choice). The last component is CAS (creativity, action, service) which are volunteer projects outside of school. You must log a certain amount of volunteer hours in each activity.
To clarify, I will give an example of what I did. My courses were: HL English, HL Psychology (instead of history), HL French, SL Environmental Science, SL Math, SL Music. My extended essay was written on traditional Icelandic music and its influences on modern day Icelandic music, and my CAS activities were: creative-community orchestra, active-marching band(or being part of a sports team), service-tutoring french. At the end of your second year all your material (exams, internal assessments, extended essay, volunteer work) is sent away to different countries and assessed and if you receive more than a certain amount of points (24 I think) you receive your IB diploma.
