Other Qualifications Information

Other Qualifications

We are happy to accept many other types of qualifications, such as the French Baccalaureate, Romanian Baccalaureat, German and Austrian Abitur, Diploma di Esame di Stato, Spanish Bachillerato, Polish Matura, Apolytirion, Canadian High School Diploma, HKDSE, CBSE-AISSE / CISCE-ISC or CAPE.

Please contact the Chemistry Admissions team (details on the left) for more detailed information and enquiries, or click here to see the minimum college entry academic requirements.

Combination of Subjects

We typically prefer the third subject offered to be Biology, Physics or Economics, in addition to pre-requisite subjects Chemistry and Mathematics. However, we do accept applications from students with alternative third subjects, such as Further Maths, relevant languages, business studies, humanities and other subjects.

Combination of subjects is one of several factors we consider when short-listing applicants for interview for their chosen degree programme. General Studies and Critical Thinking are not accepted.


Physics is required for the MSci Chemistry with Molecular Physics degree programmes (F1F3/F1FH). Biology is preferred (but not required) for the MSci Chemistry with Medicinal Chemistry degree programmes (F124/F125).

We are unable to accept applications without A-level Mathematics, or equivalent Maths qualification (e.g. IB HL Maths, AP Calculus BC etc.).

Language Requirements

English Language Requirements for ALL students

All candidates must have a minimum English language qualification of at least grade B/6 at GCSE/iGCSE or other equivalent qualification or proficiency test (equivalent to CEFR level A2-B1, e.g. IELTS, TOEFL, PTE).

For details of acceptable English language qualifications, and the minimum grades required by the College, please see the English language requirements for undergraduate applicants webpage.

Chemistry has set its requirements at Imperial College’s Higher Level for English Language.

Language requirements for MSci Chemistry with “a Language” for Science

For students applying for MSci Chemistry with French, German or Spanish for Science (F1R1, F1R2, F1R4), we require grade B at AS-level in that language, or an equivalent qualification (CEFR Level B1-B2). An A-level or equivalent would be preferred but not essential. Language skills are usually assessed at interview.

Language requirements for MSci Chemistry with Research Abroad degrees

For students applying for MSci Chemistry with Research Abroad degrees (F104, F101), we typically require at least grade B at iGCSE/GCSE in the relevant language (or equivalent qualification, at CEFR Level A2-B1) where the placement takes place in a non-English speaking country. There are no additional language requirements for placements in countries where English is widely used.

Further Information and Q&A

Should I apply for more than one course?

We strongly recommend applying for only one of our Chemistry degree courses. There are no individual quotas for each course and our entry criteria are the same. In addition, it is easy to swap between the chemistry degree courses at a later date.

Is it easy to change between the Chemistry courses offered?


Years 1 and 2 of all degree programmes follow the same core Chemistry content/modules, supplemented by one ancillary module that is designed for specific degree programmes. This structure allows many of our students the opportunity to transfer to a different degree programme up until the end of Year 1 (or end of Year 2 in some cases) providing they have studied the appropriate ancillary subject and/or meet certain pre-requisites.

Are entry requirements different for BSc and MSci courses?

The minimum entry requirements for all our courses are equivalent and are currently set at AAA at A-level including Maths and Chemistry (contextual offer). The third A-level specified by us in your offer is dependent upon the A-level subjects you are studying and the course applied for (see the Combination of Subjects tab above).

Our typical offer varies from A*AA to A*A*A, and the conditions of the offer depend on a variety of different factors.

Please see the Subject Requirements for 2021 entry section above for information on other qualifications.

What do you look for in an application?

Your predicted grades should meet our minimum entry requirements, and we usually prefer students to be taking Biology, Physics or Economics alongside Chemistry and Maths, as this combination provides a broader and more comprehensive scientific training overall. Other third subjects are indeed accepted for consideration, however, especially where they support the degree programme, and you can find further details in the Combination of Subjects section above.

Your personal statement should convey enthusiasm and commitment towards studying Chemistry at University, discussing what you enjoy doing/reading/studying, what you have learned and what skills you have gained from the experiences you have had (both in Chemistry, in other subjects) and hobbies and interests that are personally important to you.

Obtaining relevant work experience is not a specific requirement for studying Chemistry with us.


Will I be required to attend an interview?

We require all students who are shortlisted in the first step in the Admissions process to attend an interview as part of an interview day. During the 2020-21 UCAS application cycle, all interview days will be online and interviews offered via Skype.

In addition to a 20 minute interview in the afternoon, this year there will be informative pre-recorded talks on studying at Imperial College, student finance, accommodation, student life and our White City campus. There will be the opportunity to meet and talk to current undergraduate students and to the admissions tutor at online Q&A sessions in the morning, specifically for those invited to attend an interview.

Some interviews will be offered in the morning to accommodate overseas applicants in certain time zones.

Please see the Admissions and Interview Process section above.

The Admissions Process and Interviews

We have a two-stage admissions process in Chemistry. We consider the entire UCAS application form in our shortlisting process for interview. This includes achieved and predicted grades, combination of subjects and level of qualifications, personal statement and reference. All personal statements and references are read in detail. Interview performance and feedback then assist us in the offer-making decision process.

We also use information about mitigating circumstances (such as health conditions, caring responsibilities, school disruption) that may have affected a student's education. We take information about school performance, the area in which a student lives and other factors in to account also, as part of our widening participation policy (see Inclusive Admissions Process drop-down below).

Those applicants short-listed, will be invited for an academic interview. This year (2020-21 UCAS application cycle), all interviews will be via Microsoft Teams with two experienced members of Chemistry academic staff, which will last approx. 20 minutes.** We are looking to see your motivation and enthusiasm for Chemistry and will be discussing your interests in Chemistry and outside the subject.  It will include questions about Chemistry-related topics, to assess your overall background knowledge and understanding, and your problem-solving skills - your thought-process in using your knowledge to work out solutions to problems. Your personal statement is a good starting point for Chemistry-related questions.

**Students applying for the MSci Chemistry with French, German or Spanish for Science programmes (F1R1, F1R2, F1R4) who are short-listed for interview, will have their language skills assessed by a relevant tutor from the Centre for Languages, Culture and Communication. Further details about how this will work this year will follow shortly.

We typically short-list up to 75-80% of applicants for interview, and typically make offers to up to 75% of interviewees. We aim to contact all interviewees directly, within one week of interview, to inform them if we are able to make them an offer. The detailed offer conditions can only be seen online by logging in to UCAS Track, which will be updated online soon after a decision has been made.

Inclusive Admissions Process

The Department is committed a fair and inclusive admissions process, and to widening participation of under-represented groups and supporting them in accessing higher education. All applications are reviewed in their entirety, on a case-by-case basis, and we use academic interviews to assist in the offer decision-making process. Predicted grades are not the sole factor we look at in assessing future potential, and we also take in to account mitigating circumstances or contextual information, which may have had an impact on an applicant’s education.

The Faculty of Natural Sciences have approved a widening participation (WP) policy as part of a wider WP policy for the college. To find out more information, please visit the Admissions Schemes webpage.

For the 2020-21 UCAS application cycle, our interview days and interviews will all be online. No travel will be required for attending interviews therefore, and the department is currently unable to accommodate visitors due to current COVID restrictions and guidelines.
