How DeepThink supports Clementi Town Secondary 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

Clementi Town Secondary School (CTSS) is a government co-educational secondary school located in Clementi. Established in 1980, the school serves students from a range of backgrounds and operates under the motto "Aspire and Grow." Its stated vision centres on building a community of learners who value one another and pursue excellence with purpose.

The school's educational philosophy emphasises holistic development, aiming to nurture students who are resilient, reflective, and community-minded. CTSS runs an Applied Learning Programme (ALP) in STEM — Emerging Technologies, known as MARS (Mastery through Application and Research in STEM), which gives students opportunities to engage with hands-on technology projects. The Learning for Life Programme (LLP) focuses on Community Youth Leadership, combining service-oriented activities with leadership development. CTSS does not have SAP status or an Integrated Programme track. It implements Full Subject-Based Banding (FSBB), which allows students to take individual subjects at different levels based on their strengths.

Admission Process

Entry to CTSS at Secondary 1 is primarily through the PSLE posting exercise. Based on 2025 data, the indicative cut-off points for non-affiliated students were: Posting Group 3 at 9 to 13, Posting Group 2 at 21 to 23, and Posting Group 1 at 25 to 28. CTSS is non-affiliated, so there are no priority admission advantages from feeder primary schools. These figures represent the score of the last student admitted in that posting cycle and may vary from year to year.

Students may also apply through the Direct School Admission (DSA) scheme before PSLE results are released. DSA categories at CTSS include sports (such as badminton and basketball), performing arts (drama, dance, band), leadership and uniformed groups (NCC, NPCC, Guides), and STEM. Applications are submitted through the MOE DSA portal, which typically opens in the middle of the year.

Under Full Subject-Based Banding, admitted students are placed into mixed form classes and take subjects at G1, G2, or G3 levels according to their individual performance, rather than being assigned to fixed streams.

Curriculum and Academic Programme

CTSS offers an O-Level curriculum with a broad range of subjects. Core subjects include English Language, Mathematics (Elementary and Additional), Sciences (Biology, Chemistry, Physics), Social Studies, and Physical Education. Elective options cover Art, Principles of Accounts, Computing, Design and Technology, and Literature in English. Humanities subjects are offered as Social Studies paired with Geography or History. Mother tongue languages — Chinese, Malay, and Tamil — are available at standard and higher levels.

The FSBB framework means students can study subjects at different levels. For instance, a student may take Additional Mathematics at G3 while studying another subject at G2, depending on their aptitude.

In terms of academic outcomes, the 2024 O-Level cohort recorded an 86% distinction rate in Pure Chemistry, 58% distinction in Additional Mathematics, and 100% pass rates across the pure sciences. The school also achieved first place in the All Singapore Secondary Mathematics Competition (Upper Secondary Normal Academic) in 2023. Students have access to the MARS programme, which integrates research-based STEM learning into the curriculum.

For students who want additional support with Mathematics — whether Elementary or Additional Math at the O-Level — DeepThink is a math tuition centre that offers structured programmes aligned to the MOE syllabus, which some CTSS families have found useful for reinforcing classroom learning.

Facilities and Co-Curricular Activities

The CTSS campus includes smart classrooms with interactive technology, a library, dedicated science and computer laboratories, a sports complex, and arts studios. The school has also upgraded its STEM laboratories to support the MARS programme.

Co-Curricular Activities (CCAs) are compulsory and the school offers more than 20 options across four categories.

Sports: Badminton, Basketball (Boys), Netball (Girls), Football (Boys), Volleyball (Boys), Wushu, and Outdoor Adventure.

Uniformed Groups: Girl Guides (Girls), NCC Land (Boys), NCDCC, and NPCC.

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

Clubs and Societies: Science and Technology, Art and Crafts, and Infocomm Technology (Media Production).

CCA involvement is considered in DSA applications and contributes to the school's focus on developing character, teamwork, and leadership alongside academics.

Student Life and School Culture

CTSS operates on a single-session schedule. Class sizes are approximately 40 students, and each class has a dedicated form teacher who provides pastoral support. The school's culture is grounded in values such as respect and responsibility, with structured programmes for character development including resilience workshops and peer support initiatives.

Well-being is addressed through regular check-ins and access to school counsellors. Anti-bullying efforts are proactive, incorporating assemblies and student-led peer support. The Learning for Life Programme in Community Youth Leadership, Values in Action (VIA) projects, and Character and Citizenship Education (CCE) lessons are integrated into school life to develop empathy and civic awareness.

Special Educational Needs Officers are available to support students with mild special needs, providing learning and behavioural assistance within the regular curriculum and CCA settings.
