Firstly, this will be DS' decision, not mine, and we will support him whatever. However, our local 6th form college offers the IB and he is pretty set on taking it next year.
My thoughts are - why give yourself more work to do? I think that the IB does help with skills prior to university, but most students going to uni won't have done it so he won't be at a massive disadvantage by not taking it.
If he does take the IB, he'll have to continue with a language (and he's always moaned about his language GCSE), plus maths which he is good at but does not enjoy). I get that he still gets to do four subjects he DOES enjoy, rather than just the three he could do at A level, but I am just unconvinced that it makes the whole thing worth it.
What do you think? Is the IB lots more work? Is the work worth the kudos and the additional skills?
