To me, Biochemistry, Immunity, and Infections II is a very advanced course for Secondary School Students. In particular, immunology could be difficult for students to understand.

The course was first offered online in 2022, when Hong Kong was still bothered a lot by COVID-19; fortunately, the course could be offered again in the spring of 2023 face-to-face. Seven elite students joined us on 6 and 13 May; where two of them had been joining my Program for the Gifted and Talented courses for more than once!

Although I am so delighted to teach my students, I often remind them to explore more, for example, instead of taking courses in the same university, they should try the learning experience offered by other institutes. Similarly, they should also try other fields of study to expand their horizon.
