الأسئلة الشائعة

تعلّم عن المجالات الجديدة في الكيمياء وكيفية المشاركة: حول IChC

General Information

What is IChC?
Chemistry is the central science that bridges physics, biology, and materials science, exploring the composition, structure, and transformations of matter. From understanding the molecular basis of life to developing new materials and medicines, chemistry touches every aspect of our daily lives. The International Chemistry Competition embraces this spirit of discovery and gives students the opportunity to challenge their chemistry knowledge and to learn more about this fascinating subject beyond the typical school curriculum.
What makes IChC unique?
Internationality, Digital Accessibility, Real-World Research, Adjusted Difficulty, Online Tools for Teachers, Supportive Alumni Network, and more. All details are available here: About IChC
I have already participated. Should I participate again?
Yes, of course!
Are teams allowed?
Everyone has to submit their own solution papers in all rounds. However, for the Qualification Round, you are allowed to work on the problems with your friends and classmates together. Working together or receiving help from other people is not permitted in the Semi-Final and Final Round. You can find more about rules and cheating policy here: Cheating Policy
Where do I find the problems of last year's competition?
You can find them here: Training Problems
How can I prepare for the competition?
You can learn more here: Training Problems
What are the social media links of IChC?
Will there be verification codes on the certificates?
Yes, all of your IChC certificates have verification IDs. This enables others to verify the authenticity of the certificates and documents: Verification page
How does IChC compare to other science competitions? (e.g., IChO)
Comparing the International Chemistry Competition to other science competitions can be misleading: IChC does not intend to be an alternative to established competitions (e.g., International Chemistry Olympiad) or their national variations and actively encourages students to take part in such opportunities.

Instead, IChC serves as a supplementary program designed to engage a wide range of students, particularly those just beginning to develop an interest in chemistry and related scientific subjects. It focuses on accessibility, making it a platform for students of all skill levels to explore and grow their understanding of chemical phenomena and scientific reasoning.

How does my teacher approve my Semi-Final Round Exam?
After you log in to the Semi-Final Round Exam platform at https://intchc.org/exam, an approval code will be displayed on your screen. Your teacher must enter this code into a form that appears in their teacher account to approve and start your exam.
Do teachers need to enter the approval codes of all participants?
If a teacher supervises multiple students at once and the participants start the exam simultaneously, it is sufficient to enter only a single approval code if all participants arrive at the approval page in the Semi-Final Round Exam platform.
Who can supervise the Semi-Final Round Exam?
The person supervising your Semi-Final Round Exam must be an active teacher (not retired) employed at a government-accredited school or university. The teacher must currently be an active teacher or professor and must not be related to you (no family members). The teacher must be able to prove their employment and teaching duties.
How do I qualify for the Final Round?
To qualify for the Final Round, you must score at least 8/10/12 points out of 18 possible points in the Semi-Final Round. The Semi-Final Round consists of five problems: two basic problems (4 points each), two advanced problems (6 points each), and one research problem (8 points).
How can I access the Semi-Final Round Exam?
If you have successfully qualified from the Qualification Round and registered for the Semi-Final Round, you can access the exam platform at https://intchc.org/exam by logging in with your IChC participant account credentials during the exam period (between Sunday, 10 May 2026 and Tuesday, 12 May 2026).
What should I do in case of technical difficulties during the exam?
First, inform your supervisor (if using teacher supervision). Take screenshots of the encountered issue if possible, then try to reload the exam page (and log in again if necessary). After the exam, if we detect any time irregularities, you will have the option to explain any technical issues that occurred.
What should I do with the approval code at the beginning of the Semi-Final Round Exam?
The approval code is used to verify that you are currently being supervised by your teacher. You need to give this code to your teacher so they can enter it into their teacher account to approve and start your exam. After successful verification, the exam will automatically progress to the next page.
How can my teacher register?
Your teacher must register online at https://intchc.org/teacherinfo. The IChC team will review the registration and approve or reject the teacher within a few days.
Can you refer me to some teachers who can supervise my Semi-Final Round Exam?
Unfortunately, we cannot provide you with teachers to supervise your Semi-Final Round Exam. Please contact teachers at your school or other nearby schools. If you cannot find a teacher, you can use the online supervision system instead.
Does the teacher have to be from my school?
No. The teacher can be from any government-accredited school or university, as long as they meet the requirements (active teacher, not retired, not related to you).
Does the teacher have to be a chemistry teacher?
No. The teacher can teach any subject, as long as they are an active teacher at a government-accredited school or university.
There are multiple Semi-Final Round participants in my school. Can we have the same teacher?
Yes. A single teacher may supervise the exam for multiple participants at the same time. If there are other Semi-Final Round participants from your school, it is required that the same teacher supervises all students simultaneously. Please contact your teacher and inform them about the other participants.
My teacher was rejected as a supervisor. What should I do?
Please ask another teacher who meets the requirements and can prove their employment at a government-accredited school or university. The rejected teacher can also register again with additional or corrected information or documents if something was missing from their initial registration.
What materials and tools are allowed for the Semi-Final Round?
You can bring blank sheets of paper (not more than twenty) and pens (not more than three) to write your solutions during the exam. You can bring a calculator. You may also bring something to drink. No other materials or tools are allowed. You are not allowed to bring your own copy of the research paper, but it will be available in the exam interface. Your computer, laptop, or phone must only be used to access the exam platform at https://intchc.org/exam.
What is the preparation phase?
The preparation phase begins on Friday, 8 May 2026 when all qualified and registered Semi-Final Round participants receive a research paper via email and through their participant account. During this phase, you should read and familiarize yourself with the research paper, as one of the exam problems (the research problem worth 8 points) will require you to apply concepts from this paper. The paper is in English, but you may use translation tools and AI to help you understand the material.
Will the research paper be in different languages?
The research paper is provided in English only. However, you may use translation tools and AI to help you comprehend the material and translate it into your preferred language.
Will the questions of the Semi-Final Round Exam be in different languages?
The exam questions will be available in multiple languages. The specific languages available will be displayed in the exam interface when you log in.
How will I scan my handwritten answers after the exam?
After the 60-minute exam finishes, you will have 10 minutes to upload clear scans of your written solutions using your phone. You will scan a QR code shown on the exam screen, which will take you to the upload interface. If you use your phone to take the exam, you will need a second phone for scanning and uploading. This is why we strongly recommend using a laptop or computer for the exam itself. Make sure to write clearly, use a new sheet of paper for each problem, and write the problem number at the top of every page.
Will my exam also be recorded if a teacher supervises me?
No. If you choose teacher supervision (Option A), your exam will not be recorded via webcam or phone. Your teacher will supervise you in person and take a photo of the exam conditions during the exam. The online supervision system with webcam and phone recording is only used if you choose the supervision without teacher option (Option B).

Final Round

How does the Final Round take place?
The Final Round is a single 30-minute online exam with around 20 questions. The exam takes place at home via an online exam portal and is supervised using an online supervision system (no teacher supervision required or allowed). The exam includes two types of questions: (1) Short-answer questions (1-2 minutes per question; 1-2 points): Give a single word or number as response.

How many questions does the Final Round have?
The Final Round consists of around 20 questions and takes around 30 minutes. The exam includes two types of questions: (1) Short-answer questions (1-2 minutes per question; 1-2 points): Give a single word or number as response. (2) Multiple-choice questions (1 minute per question; 1 point): Select the correct answer from four options. Questions are shown one-by-one for a limited time. There are no negative points for incorrect answers.
What help/tools are allowed for the Final Round?
You can use blank paper and pens during the exam for notes. Not allowed: Calculators, written notes, or the Semi-Final Round research paper. The computer/laptop/phone must only be used to access the Final Exam website.
What if two participants have the same number of points in the Final Round?
In this case, the results of the Semi-Final Round and of the Qualification Round will be used to determine the final winner based on the total points. If the tie remains, both participants will receive the same award and split the cash prize. However, this has never happened before.
When will the final winners be announced?
The results of the Final Round and IChC will be announced on Monday, 15 June 2026.
