Malibu_StacyI did it, I hated it then but now I'm glad I did. I think it really gave me an advantage compared to my other friends who did the regular, swedish program.
This, it may be more work while you are doing it, but it is completely worth it when you finish and will give you a huge advantage in life. Its not for everyone though, it takes loads of time and effort to do. I only get the choice between IB and A-level, the british system, and they probably both take the same amount of work so Im going for IB, starting next year.
My school is pretty intense academically though, so thats just us. Also, to those of you saying its a waste to do it, it is a waste to NOT do it, because of how much you will benefit from it. Don't be lazy you're in highschool not fucking kindergarten. Play-time is over kids.
