HKU CS upper year COMP courses

Hi everyone! I will be an exchange student for the fall semester and would love to hear thoughts and opinions around the following CS courses (content, teaching staff, workload, etc.):

• COMP3322 Modern technologies on World Wide Web
• COMP3330 Interactive mobile application design and programming
• COMP3355 Cyber security

I am a CS student from Canada (UofT) and hope to transfer over 2-3 third-year COMP3xxx courses for credit during exchange! Fortunately it is a pass/fail so my priority will be exploring the city/travelling and student life as opposed to good grades.

These were the available courses offered for the 2024-2025 year so maybe things will change, but happy to take other course suggestions! Thanks!
