Is the CSCA Exam Hard? An Honest Look at Difficulty (2026–27)

Is the CSCA exam hard, really?

There is no official measure of CSCA difficulty. The exam is new, with the first session held on December 21, 2025, and the organizer has not published average scores, pass rates or score distributions. Anyone giving you a precise figure, such as the percentage of students who pass, is guessing. What we can judge honestly is the syllabus, the format and the rules, and together they give a clear picture. For the basic facts behind this article, see our CSCA exam 2026–27 guide.

The topics themselves are standard high school material. The official Mathematics syllabus groups content into sets and inequalities, functions, geometry and algebra, and probability and statistics, with only the basics of derivatives. A student who did well in a science stream at higher secondary level will recognize most of it. What turns familiar content into a hard exam is the mix of speed, working by hand and single-choice traps. To test yourself on real syllabus topics, try our CSCA math sample questions.

Background matters a lot. Students from school systems with stronger mathematics preparation are likely to find the requirements easier to meet. In other words, the CSCA is not equally hard for everyone. Your curriculum, your language and the amount of practice you do matter more than the exam itself.

What makes the CSCA exam difficult?

• Time pressure: about 75 seconds per question in Mathematics, Physics and Chemistry. A question you could solve in three minutes at home is too slow here.
• Working by hand: the published exam rules do not list a calculator among permitted items, so you work out fractions, square roots, logarithms and trigonometric values by hand, which is a big change if your school allowed calculators.
• Breadth: one 60-minute Mathematics paper can jump from inequalities to probability to analytic geometry, so you cannot skip whole topics.
• Curriculum gaps: some topics may not be in your school's syllabus, or may come later than you expect.
• Language: if your paper language is not the language you learned science in, unfamiliar terms slow you down.
• Single-choice traps: wrong options are often built from common mistakes, such as a sign error or a forgotten unit.
• Exam conditions: a home-based exam with live remote proctoring has strict rules about your room and screen, which can feel stressful the first time.

Which CSCA subject is the hardest?

There is no official data on which subject students find hardest, and the answer depends on your strengths. Here is what tends to make each paper demanding:

• Mathematics: the broadest syllabus and the one everyone takes. Functions, inequalities, sequences, analytic geometry, vectors and complex numbers can all appear, and you must calculate by hand.
• Physics: questions often need manual calculation, such as working with trigonometric values in mechanics problems, plus a clear grasp of units and formulas.
• Chemistry: a mix of recall (reactions, properties, periodic trends) and calculation (moles and concentrations), so gaps on either side cost marks.
• Professional Chinese: for non-native speakers this is often the most demanding paper, because all 80 questions are in academic Chinese at about 67 seconds each. It is only required for Chinese-taught programs.

Because Mathematics is compulsory and covers the widest range of topics, it deserves the largest share of your time. Our CSCA mathematics syllabus 2026 breakdown lists every topic, so you can mark what you already know and what you still need to learn.

Is the CSCA harder than the gaokao?

Probably not, judging by format, though no official comparison exists. The gaokao is China's national university entrance exam for domestic students. Its mathematics paper typically lasts 120 minutes, is worth 150 points and includes multi-step problems where you write out full solutions. The CSCA Mathematics paper is 60 minutes of single-choice questions built around fundamentals, so it is shorter and narrower.

That does not make the CSCA easy. You compete with other international applicants for places and scholarships, the exam is new so there are few past papers, and working without a calculator surprises many students from systems where calculators are normal. Treat the gaokao comparison as reassurance about the content level, not as a reason to prepare less.

Students also ask whether the CSCA is harder than the SAT. The two are built differently. The digital SAT allows a calculator for its whole math section, while the CSCA's published exam rules do not list a calculator among permitted items, and CSCA Mathematics includes topics such as basic derivatives that the SAT does not test. If you are used to SAT-style math, expect working by hand to be the biggest adjustment. Our CSCA vs SAT, ACT, A-Level and IB comparison goes into more detail.

Does your school background make the CSCA harder?

Your background changes how hard the CSCA feels more than anything else. If you studied Mathematics, Physics and Chemistry to the final year of higher secondary school, you have seen most of the content before. If you dropped mathematics after grade 10, or studied in a humanities stream, Mathematics will take real work. Remember that it is compulsory even for humanities and business applicants.

Language matters too. You can take the science subjects in Chinese or English, so pick the language you studied them in. Students from Nepal, Pakistan, Bangladesh, Indonesia or Africa who learned science in English should usually choose the English papers. If you studied in another language, spend extra time on subject vocabulary, because one word you do not recognize can cost you a whole question.

What score do you need, and does that change the difficulty?

No national pass mark exists. Universities set their own requirements: some use the CSCA as a minimum entry requirement, while others treat it as one part of a wider review. So the real question is not whether the CSCA is hard in general, but how hard it is to reach the score your target program wants. A higher score matters most for competitive programs and scholarships, because universities use CSCA results in both admission and scholarship decisions.

Check the admission guides of your target universities, or ask their admissions offices in writing, before you decide how much time to invest. Be wary of any website quoting a fixed cut-off score without an official source.

How can you make the CSCA easier?

You cannot change the exam, but you can change how ready you are. Begin by measuring where you are today: set a timer and try free CSCA mathematics practice questions with your calculator out of reach. Then follow these steps:

1. Confirm your subjects and paper language for each target program.
2. Compare the official syllabus with what your school covered and list your gaps.
3. Fix the biggest gaps first, starting with Mathematics.
4. Put the calculator away for good and practice mental arithmetic daily.
5. Train your pace until 75 seconds per question feels normal.
6. Study in the language you will take the exam in.
7. Take a full timed mock exam every week in the final month.
8. Review every mistake and keep an error log of the traps that caught you.

For a week-by-week schedule that builds from topic review to full mock exams, follow our 90-day CSCA study plan.
