This Site's Recommendation:
This site recommends not doing IB because of the lesser workload. IB involves a LOT of writing, so much so that students in IB say that it has improved their handwriting. Additionally, to earn your IB Diploma, you have to take a lot of IB Courses, restricting the amount of electives you can take. Additionally, the IB Diploma requires writing a 5,000 word essay reflecting on your time in IB.
However, if you wish to go to college abroad, then this site would recommend to choosing IB.
