I had two children earn a full IB diploma and each took six or seven exams as well as three AP exams.
College was intellectually harder than IB for both my kids. One attended CWRU in physics and one attended GaTech in Computer science. IB prepared them both for the math sequences and physics sequences they took, and placed them both out of chemistry, English, and social sciences, as well as placed for math and physics too. They got organized in 11th grade and that made things easier, but the step up to college is much bigger than the step up from 10th grade to IB 11th grade for difficulty.
IB is not particularly hard material, except for HL math for a kid who has trouble with proof based mathematics , its just time consuming , but the level is more or less advanced high school/early college.
so if a child finds IB “hard” they are not going to be able to earn As at any top college. Absolutely sign up for the full IB diploma program. It will teach you to read and write well, and also write up lab reports. Its not that challenging, for most very bright kids, the way college will be!
An IB diploma may , might get you a year of college credits and placements, especially in states that legislate that,
so Georgia, Florida and Colorado public universities.
The college students without IB preparation will have to learn to write in college, and you will be way ahead in writing…
Success in IB is all about planning so it will be all nighters if you do not plan, but if you plan, more like two hours a night, for four HL classes, and two SL classes. Also realize that 12th grade is way easier than 11th grade, as 12th graders in IB are reviewing a lot more, than 11th graders, who are doing more assessments that count for your final IB score in that class. Sort of like “mid term exams” but they are homework that get handed in to IB for grading. Most kids double up on either social sciences or physical sciences as well, so do MORE than the IB diploma requires.
IB is just not that bad for a motivated student.
The extended essay can be researched and written over the summer. But we know plenty of kids
who did that EE in one week. Its possible, but science EEs need to have actual experiments so plan ahead!
Its just about planning and following directions.
Also, Theory of Knowledge is a good class if you are considering a career in law.
