Online Classes

Online classes at Chemistry Domus are designed to be just as effective as our physical classes.

  • Content for online classes and physical classes are exactly the sameChung will go through core concepts and key skills for the week, after which you will work through carefully curated practice questions to lock down those concepts and skills.

  • Students will have access to on-demand video lectures that they can watch (and rewatch) at any time to learn a new concept, or refresh an old one, as well as on-demand video practice questions where you can learn key exam skills and strategies to solve particular question types;

  • Students will also have access to WhatsApp consultation, where they can clear any questions and doubts with Chung anytime of the week.

Our Online Classes Are

Online class sizes remain small, and students are expected to send their answers to Chung at various points of the class, such that they remain accountable for their learning during the virtual class.


Our online classes are not one-directional.

Chung will constantly check on the progress of students with directed questions, and students can also ask questions at any time.


Our physical location is in the East, but with our online classes, you can enjoy the same level of teaching from Chung no matter where you are in Singapore.

2-hr Real-time Interactive Classes

During the 2-hr real-time interactive classes,​

  • Chung will highlight the core concepts and key skills for the week,

  • students will do practice questions emphasising these concepts and skills,

  • Chung will go through the practice questions to ensure that the key concepts have been locked down,

  • classes remain small such that Chung can maintain visual contact with the students just as in a classroom to gauge their learning progress, and

  • students can ask questions at any point in time, just like in a physical classroom.

The online classes are conducted using the Zoom platform. Students will only need to install the Zoom application on their devices, and it is free for the students. Students do not need to sign up for an account.

Online Video Lectures and Practice Questions

Chung has built an on-demand video library for the entire A Level H2 Chemistry syllabus.

Regular students of Chemistry Domus will be able to watch (and rewatch) videos for any of the lessons that they have attended, so that they can refresh a concept or skill at any time.

Students can also subscribe (for a fee) to the on-demand videos for topics that they might have missed.

Watch a sample JC1 video for a core skill for Reaction Kinetics here, or watch a sample JC2 video for the review of Organic Chemistry mechanisms here.
