IB Program?

Hey, I was just wondering if anyone here is taking part/has taken part in the International Baccalaureate Diploma Programme? For those of you that don't know the International Baccalaureate Diploma Programme is designed as an academically challenging and balanced programme of education with final examinations that prepares students, normally aged 16 to 19, for success at university and life beyond. The programme is normally taught over two years and has gained recognition and respect from the world's leading universities.

I have the option to apply and take place in it over the next two years, the only thing I ask is, is the hard work worth it over all? Do you feel like all the suffering through higher level Mathematics, Chemistry and Biology was worth it? Do you feel like you are ahead of your classmates in University?
