It is said that IB students must excel at research in humanities and experiments in sciences, prepare presentations while writing a 4,000-word EE, and complete 150 hours of CAS activities. Just hearing about it sounds stressful. So, let’s get to know what exactly IB is with CheersYou（清柚教育） Bro.
Among the three major international curricula, the IB is overall the most challenging—not because each subject is exceptionally deep, but because it emphasizes all-round development. The scope is broad, and the challenges are greater throughout the learning process.
However, the diversity and systematization of the courses, along with various clubs and off-campus activities, sharpen time management, project management, research skills, and interpersonal and problem-solving abilities—advantages unmatched by other international programs.
When applying to US universities, high scores alone are not enough. Admissions officers look beyond grades for additional strengths. As a result, many US institutions have a certain preference for IB students. This preference does not automatically add points to your application, but rather the well-rounded skills developed through IB open up more advantages and opportunities in university and beyond.
The IB program is divided into four stages: Primary Years Programme (PYP), Middle Years Programme (MYP), Diploma Programme (DP), and IB Career-related Programme (IBCC).
Today, CheersYou（清柚教育） Bro will mainly introduce the IB-DP stage. What exactly is this phase of the IB program? What do students study? How are credits converted? Let's find out.
What Is IB?
The IB program was founded in 1968 at the International School of Geneva, initially designed for children of diplomats and business professionals who moved frequently. The Diploma Programme (DP, taken in the last two years of secondary school) came first, followed by the Middle Years Programme (MYP) in 1994 and the Primary Years Programme (PYP) in 1997.
One key difference between IB and AP or A-levels is that IB offers a complete, integrated curriculum. AP evaluates subject knowledge through a single exam, but IB stresses holistic development—it hones academic ability, academic report writing, and the well-rounded qualities shown through extracurriculars.
IB can only be pursued at registered IB schools. Upon successful completion, students receive a unified certificate (IBDP). If a school does not offer the IB program, students cannot take IB courses. Therefore, only students at IB World Schools can study IB, and IB scores are accepted for university admissions in nearly every country.
For Chinese students, IB scores typically serve three main purposes:
In countries with four-year undergraduate programs like the US and Canada, IB courses can be used to earn college credits.
Because of its international recognition, IB scores can be used directly for university applications without needing other exams or courses, such as in Canada, Australia, and the UK.
As a more rigorous secondary curriculum, IB scores often give applicants a competitive advantage when applying to universities.
Course Structure
The IB program consists of three core components plus six subject groups. The six subject groups are offered at Higher Level (HL) and Standard Level (SL).
The three core components are:
TOK (Theory of Knowledge): An interdisciplinary course that challenges students to question the bases of knowledge, recognize subjective and ideological biases, develop skills in analyzing evidence, and present reasoned arguments.
EE (Extended Essay): Students conduct independent research on a self-chosen topic and write a 4,000-word essay (or 4,800-character essay in Chinese).
CAS (Creativity, Activity, Service): This core component encourages students to share their talents and skills through experiential learning.
The six subject groups are:
Group 1: Language A (mother tongue)
Group 2: Language B (acquired language)
Group 3: Individuals and societies (history, geography, economics, philosophy, psychology, etc.)
Group 4: Experimental sciences (physics, chemistry, biology, environmental systems, etc.)
Group 5: Mathematics (mathematics higher level, mathematics standard level, mathematical studies, etc.)
Group 6: Arts and electives (visual arts, music, theatre, etc.)
When selecting courses, students must take the three core components and six subject courses. In the six subject groups, at least one course must be chosen from each of the first five groups; Group 6 is optional. If a student does not choose a Group 6 course, they select an additional course from Groups 1–5.
HL and SL courses differ only in difficulty and depth, not in essential structure. SL courses require 150 instructional hours, while HL requires 240 hours. Students must take 3–4 HL courses and 2–3 SL courses.
Credit Conversion
Scoring system:
The maximum IB score is 45 points: 7 points from each of the six subject groups (maximum 42) plus up to 3 points from the core components. To earn the IB diploma, students need at least 24 points; below 24, no diploma is awarded.
Credit conversion:
In the US and Canada—In Australia and the UK, since undergraduate degrees typically last three years, IB scores are mainly used for admission and generally cannot be exchanged for credits.
IB credit conversion generally follows these guidelines:
1. The IB diploma (minimum 24 points total) can earn up to 30 credits at most institutions. Most schools accept IB scores, but some—like Harvard—do not.
2. Individual courses generally need a score of 4 or above to earn credit. Some courses or institutions may require 5, 6, or 7. Higher scores usually yield more credits. For example, at Johns Hopkins University, a 6 in IB Physics might earn 4 credits, while a 7 could earn 8 credits.
3. For competitive US universities, a score of around 37 is expected. For Top 30 schools, aim for 39 or above. For Ivy League or equivalent, a total subject score of 40+ plus strong EE/TOK points (at least 42 total) is recommended for a solid chance.
Study Tips
Finally, CheersYou（清柚教育） Bro offers some advice for those preparing to study IB:
1. Don’t be overwhelmed by the variety of courses and assignments. Make good use of class time, review regularly, and manage your time well. Avoid procrastination, and achieving a good score is very possible.
2. IB encourages critical thinking; rote memorization and drilling won’t work as well. Reflect on your learning, draw connections to real life, and stay proactive by exploring and asking questions. YouTube has many helpful videos, and self-study is encouraged.
3. Balance academics and interests. Actively join clubs and off-campus activities—your sense of social service, organizational ability, and leadership skills will grow tremendously.
4. When choosing courses, don’t rush to prove yourself by loading up on high-level courses. Universities look at your final total score. While preparing for US applications, manage your time well and prepare for standardized tests.
