Im in my 2nd year of the IBO and i got a ton of problems with it!
CAS...i mean what is the point...serriously its not proving anything if your FORCED to do it -.- *creates voodoo doll of CAS-creator*
And then ToK, ok if you have a good teacher it could be decent, but if they just toss you the dictating philosophy teacher...its pretty much turned into my art class!
The EE isn't So bad, i did it in one week over the summer, and that was with going out and staying at gf's house a few nights. and another weekend for corrections. Dont really worry about that ****, just choose something you are interested in or you'll melt your brain.
It is way more work then A lvls though... people who usualy work harder then me work almost half the time i do, and I'm not THAT into it. On paper it does sound great like youll appreciate it afterwards as they are better qualifications then A lvl...however as someone already said most Unis dont really appreciate this in the UK.
Think about what you want to do in Uni, if you got a good idea, personaly, i would say go for it in A lvls. But if you havnt got a clue IB isnt so bad ( i still don't :P), its also international (yay!) so good if you want to study abroad.
In the end this is all about your job, and I hope most people here don't want thier lives ruled by thier job. Most courses in Uni still allow you to do anything, as they show the boss you can be dedicated to something, and be good at it. Only stuff like teaching, sciences, medicine, etc require particular courses. And if you wanted to do something like that you'd know, right?
If i could rechoose (like i'm going to do another year of this **** xD) I'd go A lvl and just choose things I enjoy....
School in a few hours *sigh*..oh well at least i got ToK on mondays...zzzz |-)
