Here, by grade 12 I'm refering to the second year of the study in IBDP. (Of course, grades 9-11 completed in the national course.)
I would STRONGLY advise you not to do that. I doubt a school would even let you do that unless they're dumb.
In theory, yes, but in practice it is so difficult (3HLs + 3SLs + EE + CAS + TOK + IAs) that even if a school let you do it, you would go crazy in the process. The sheer amount of work that has to be done (not too difficult, just very time-consuming if crammed into one academic year) is insane.
in my school if u come in yr 13 (2nd year of IB) they will put u into yr 12 so u can start from the beginning. That means u will be 1 year older than the others but its better than cramming...
I can't see how it would be possible. There's just too much work, just by the number of hours each class needs to be taught.
Oh gosh, it's frightening just to think of trying to cram it into one year.
Two years of IB is scary enough with all the course work, I can only imagine doing it all in one! I knew a kid who did take some IB classes in his last year, but he was in IA.
we even extra lessons in our study leave befor exams, even we studied for 2 years. Thiis shows there's lots of content to cover in the IB, and also include IAs, EE and TOK.
it depends on the school and if the curriculum that you were doing before was similar or not. And it is possible to do it in one year anyway...I think. Some schools make you do certain subjects in one year anyway, so yeah. Otherwise you could go to a school that does the examinations in November and like that you would have 1.5 years to do it and not be too old when you finish. Just to reassure you, if yo do decide to start from the beginning, at my school there are 20 year olds in year 11 (our school goes up to year 13).
