What the pages say about the two maths courses

Mechanical and Automation Engineering. Any maths course is preferred except AI SL, so AI HL is included; no minimum grade is given and CUHK says preferences are not requirements. Physics: Physics is one of four preferred science options, not required.

Electronic Engineering. 'Any Mathematics subjects' covers AI HL; no minimum grade given. Physics: Physics preferred (preferably HL), stated as a preference not a requirement.

Computer Science and Engineering. 'Any Mathematics subjects' at HL covers AI HL; no minimum grade given. Physics: Physics is one of four preferred science options, not required.

Science (broad-based admission). 'Any Mathematics subjects' covers AI HL; maths is one of the preferred options, not compulsory. Physics: Physics is one of the preferred HL options, not required.

Enrichment Stream in Theoretical Physics. Only AA is named as the preferred maths course; AI HL is not mentioned, and since these are preferences rather than requirements it is not stated that AI HL is rejected. Physics: Physics HL preferred.

Enrichment Mathematics. Only AA HL is named; by contrast Mathematics and Mathematics Education names both AA and AI at HL, so AI HL is not preferred here but not explicitly rejected.

Economics. 'Any Mathematics subjects' at SL or HL covers AI HL (and AI SL); no minimum grade given. Physics: Physics is an alternative to maths in the preference, not required.

How to read an offer like this

The points total and the Higher Level grades are conditions that must all be met together. A student with 41 points and a 6 in HL Mathematics does not meet an offer that asks for 40 points with a 7 in HL Mathematics.

Where the page says a maths course is preferred, both are considered and the preference can count between similar applicants. Where it says only, the other course does not meet the requirement. If the school does not offer Analysis and Approaches at Higher Level, write to admissions before applying and keep the answer.
