About this app
This app is designed for HKU undergraduate students taking chemistry courses and requires an HKU email account to log in. In this app, you may find lecture notes and videos, assignments, extra exercises, and tutorial articles for some CHEM courses. In addition, you may start discussion threads and join the discussions in the class forums! Tutors and teachers may participate in the discussion as well. You can choose your own display name in the app. More functions are coming up soon. Stay tuned. HKU ChemApp is co-developed by the Department of Chemistry and Technology-Enriched Learning Initiative of HKU and is funded by the HKU Teaching Development Grant.
