IB is way more hardcore than normal school. Prepare for sleepless nights, all nighters, hours of homework, no free time omg, but meeting lots of new people. ^_____^
I recommend people to not take geography and chemistry (the worst two choices I made in my life), unless you want a shitload of work HOWEVER I still love geography as a course because it’s so much more interesting than chem. I’m not a sciency person and still took 2 sciences (not a good idea). If you choose the right courses, it won’t be that hard for you.
In my opinion, I would really recommend everyone to take IB because it prepares you so much for life in university. You get to have experience with writing more essays, designing own labs, and just being under the pressure of completing so many things under such little time is really intense.
