Students can log into an online learning platform called "Online Question Bank" which provides around 2,000 multiple-choice questions in six subjects - mathematics, economics, physics, chemistry, biology, and business, accounting and financial studies - from previous exam papers.

But the system will not have open-ended questions, according to Siu Wai-lok, manager of the Hong Kong Examinations and Assessment Authority's technology and research division.

"[The system] will show the estimated result in letter grades from A to D. We avoid using grading from levels one to five ... as this is an estimation after only answering multiple-choice questions, but in the real exams, students will need to answer some open-ended questions which are not included in this system," said Siu.

Students will receive their individual report while teachers will also get an overall class report so they can follow up with the students based on the data.

The system will also provide training to teachers on setting questions from suggestions made by over 100 participating schools in the pilot scheme last year.

The assessment authority said the system will be opened to 30 schools in the first stage but they will consider to increase the quota if there's an overwhelming response.

Participating schools in the scheme will need to pay HK$50,000 to use the system until August 31, 2024.

Meanwhile, the Education Bureau announced yesterday that public sector primary schools saw 14 fewer primary one classes involving around 322 students, while secondary schools have cut 22 secondary one classes involving 550 students, compared to the numbers approved in April and May this year.

A spokesman of the bureau said class numbers are affected by various factors but the figures reflect the overall change in student population due to mobility, such as relocation, parental choices, and migration of students.

He said the bureau will adopt measures to address the challenges arising from the decline in student population.
