What our students say...


Tailored for Science Lovers who Want to Tackle Environmental Challenges

The curriculum is designed to educate and prepare a new generation of students in the interdisciplinary framework of Earth System Science, with two sub-disciplines namely, Atmospheric Science or Geophysics. Under this programme, students will have early exposure to scientific issues related to the Earth System. Students will also be given opportunities to gain valuable quantitative and analytical skills and build their research and career capacities through laboratory work, field trips and research projects.

Placement Programme at Hong Kong Observatory

Every year a few qualified students will be sent out to the Hong Kong Observatory for a fascinating internship opportunity to not only embark on weather and climate research, but also to experience first-hand the nature and routines of meteorological services. Both one-year and summer placements are available.

Undergraduate Research Programme

There are many opportunities for ESSC undergraduates to conduct research. In the summer research programme, students will have opportunity to work in a research group, laboratory, or field to explore interesting and challenging questions related to global environmental change, atmospheric science, and geosciences.

For Admission Score Calculation

Score Conversion

Level 5** = 8.5
Level 5* = 7
Level 5 = 5.5

Level 4 = 4
Level 3 = 3
Level 2 = 2
Level 1 = 1

HKDSE Subject Weighting

Subjects with heavier weighting:

English, Mathematics, M1 or M2, Biology, Chemistry, Combined Science, Geography, Integrated Science, Physics

(weighting ranges from 1.2 - 2.0)

Selection Principle

Best 5

The programme calculates admission scores based on the total score of Best 5 HKDSE subjects.

Bonus points will be awarded to the 6th and 7th subjects.

More than 1 HKDSE Sitting

No penalty will be imposed

Note 1: Please note that admission to the University is on a competitive basis. Apart from public examination results, applicants' other learning experiences, prior education, and interview performance (if any) will also be considered.

Note 2: For score conversion of Category C: Other Language subjects, Grade A = 5 / Grade B = 4 / Grade C = 3 / Grade D = 2 / Grade E = 1

Note 3For 2021 entry, the best result in the same subject taken by a candidate in his/her three most recent attempts of the HKDSE examination will be used for calculation of the admission score.

Admission Grades (2020 Entry)

Programme Selection Principle in 2020 entry: Best 5

Note 1: The Total Reference Score is the total score of the applicant calculated based on the programme selection principle (where level 5** = 7 / level 5* = 6 / level 5 = 5 / level 4 = 4 /  level 3 = 3 / level 2 = 2 / level 1 = 1 for Category A subjects. For Category C: Other Language subjects, Grade A = 5 / Grade B = 4 / Grade C = 3 / Grade D = 2 / Grade E = 1).

Note 2: In the admission process, some programmes may have additional requirements (such as specifying subject requirements, assigning heavier weighting to specific subjects, etc.) which are NOT reflected in the Total Reference Score above.

Note 3: Please note that as admission is NOT based on public examination results alone, and the overall scores of students admitted to each programme vary from year to year, the information provided is for reference only, and should not be used to predict the chance of admission to any programme in subsequent years.
