How DeepThink supports Hai Sing Catholic School students

  • G1, G2, and G3 students are in separate classes, each covering the content and exam format for that stream

  • O-Level, N-Level, and SEC exam preparation built in from S3, matched to the stream your child is sitting

  • E-Math and A-Math taught in separate classes from S3 onwards

  • S1 to S5 coverage so your child can stay with DeepThink for their entire secondary journey without switching centres

The programme

What your child gets at DeepThink

Secondary Math is not one-size-fits-all. A G1 student preparing for the SEC exam needs completely different content from a G3 student heading for A-Math. We keep streams in separate classes so every session is relevant.

Frequently asked questions

Clear answers for parents

Does my child's stream affect which class they join at DeepThink?

Yes. G1, G2, and G3 students each have their own class, so every lesson matches the exact syllabus and exam format your child is sitting.

My child is doing okay in S1/S2 but I'm worried about the jump to S3. Is it too early to start?

S3 is where most students hit a wall — the syllabus gets significantly harder, A-Math is new, and SEC exam (or O-Level for the current Sec 4 cohort) prep begins. Students who build strong foundations in S1–S2 handle that jump far better. Starting early is the highest-leverage move a parent can make.

When is the right time for a secondary student to start tuition?

S1 is ideal — algebra gaps from the start of secondary compound quickly and are harder to fix later. That said, students who join in S3 or S4 can still benefit significantly from targeted exam preparation.

What makes DeepThink different for secondary students?

Stream-specific classes. Every lesson, worked example, and past-year paper is matched to your child's stream.

School Overview

Hai Sing Catholic School is a government-aided co-educational secondary school located in Pasir Ris. It was originally founded in 1959 as Hai Sing Girls' High School by the Franciscan Missionaries of Mary, operating as a Chinese-medium institution for young women. The school transitioned to co-education in 1990 and adopted its current name in 1999 to better reflect its Catholic identity.

The school's motto, Ad Veritatem Per Caritatem ("To Truth Through Charity"), underpins its educational philosophy of combining academic rigour with values formation rooted in the Franciscan tradition. Students are encouraged to develop what the school calls the "HAI Spirit" — a commitment to holistic growth through faith, leadership, and community engagement.

Hai Sing is affiliated with Catholic Junior College, and it operates as a single-session school. Two distinctive programmes shape the student experience: the Applied Learning Programme (ALP) in STEM, which focuses on Cities and Urban Landscapes through Robotics and Engineering, and the Learning for Life Programme (LLP) in Community Youth Leadership, which develops servant leadership and civic responsibility across all year levels.

Admission Process

Entry to Hai Sing Catholic School at Secondary 1 is through the PSLE posting exercise or the Direct School Admission (DSA) scheme.

Based on the 2024 intake cycle, the indicative PSLE cut-off scores for non-affiliated students were: Posting Group 3 (PG3) at 9 to 15, Posting Group 2 (PG2) at 21 to 23, and Posting Group 1 (PG1) at 25 to 28. Affiliated applicants receive priority consideration during earlier posting phases. These figures represent the score of the last admitted student and may change from year to year.

The DSA scheme allows students to apply before PSLE results are released, based on demonstrated ability in areas such as Concert Band, Robotics, Floorball, and leadership. Selection criteria typically require a "Very Good" conduct grade and evidence of relevant achievements or skills from primary school. Applications are submitted through the MOE DSA portal.

Under Full Subject-Based Banding (FSBB), admitted students can take individual subjects at different levels according to their strengths, providing flexibility regardless of their posting group. Parents considering Hai Sing should attend the school's annual Open House — typically held in May or June — and review the DSA categories published on the school website each year.

Curriculum and Academic Programme

Hai Sing Catholic School prepares students for the GCE O-Level examinations with a broad subject offering. Core subjects include English Language, Elementary Mathematics, Additional Mathematics, the Sciences (Physics, Chemistry, Biology), and Humanities (Social Studies combined with Geography or History). Mother Tongue options cover Chinese Language and Higher Chinese, while electives include Principles of Accounts, Literature in English, Nutrition and Food Science, Art, and Design and Technology.

Full Subject-Based Banding allows students to study different subjects at varying levels based on their aptitude, which means a student in one posting group can take selected subjects at a higher or lower level as appropriate.

The STEM-focused Applied Learning Programme gives students hands-on experience through projects related to urban design and robotics engineering. These projects connect classroom learning to practical problem-solving and are integrated into the broader curriculum rather than treated as standalone activities.

The school has maintained strong O-Level results, with recent cohorts achieving pass rates above 90 percent in Mathematics and the Sciences. The Robotics team has earned recognition at national-level competitions, and the Concert Band has received distinctions at the Singapore Youth Festival. Students seeking additional support in Mathematics — whether for Elementary or Additional Maths — may benefit from structured revision at a specialist math tuition centre such as DeepThink, which offers programmes aligned to the O-Level syllabus.

Graduates frequently progress to Catholic Junior College through the affiliation pathway, and alumni have gone on to pursue degrees in engineering, the sciences, and public service.

Facilities and Co-Curricular Activities

The school's permanent campus is situated at 9 Pasir Ris Drive 6. During upgrading works, students were relocated to a temporary site at 15 Pasir Ris Street 21 (Singapore 518969), with the return to the permanent campus scheduled for December 2025. The upgraded campus is expected to feature improved learning spaces and expanded green areas.

Facilities include smart classrooms with interactive technology, science and computing laboratories, a robotics workshop, a library designed for collaborative work, sports courts and a gymnasium, and dedicated spaces for the performing arts.

Co-Curricular Activities (CCAs) are an integral part of school life, with more than 20 options available across four categories:

Sports and Games: Badminton, Cross Country, Football (Boys), Volleyball (Girls), Floorball, and Bowling.

Uniformed Groups: National Cadet Corps (Land, Boys), National Police Cadet Corps, and St. John Brigade.

Performing Arts: Choir, Modern Dance, English Drama, and Concert Band.

Clubs and Societies: Robotics Club, Infocomm Technology (Media Production), and Singapore Youth Flying Club.

CCA involvement is valued in the DSA process and contributes to students' overall character development and leadership growth.

Student Life and School Culture

School culture at Hai Sing is shaped by Catholic values of truth, charity, and service to others. The Franciscan heritage is reflected in daily practices — from morning assemblies that emphasise gratitude and reflection to pastoral care structures where form teachers serve as mentors for their students.

The school maintains programmes that address student well-being, including anti-bullying initiatives, resilience workshops, and access to trained counsellors. Students with additional needs are supported through dedicated student welfare officers. Class sizes are typically around 40 students, and the single-session format allows afternoons to be used for CCAs and enrichment.

For students transitioning from primary school, Hai Sing provides structured support through small-group mentoring and study skills guidance to help them adjust to the pace and expectations of secondary education. Parents are encouraged to establish consistent daily routines and maintain open communication with form teachers during the transition period.

The broader school community is strengthened through parent support groups and regular family-oriented events, reinforcing the sense of shared responsibility between the school and home.
