Combined Science

Our Combined Science curriculum focuses on building the connection between various chemistry topics through a systematic and guided approach.

In addition, we have incorporated workshops exclusively for Explorer Academy students. These workshops are conducted across the secondary 3 and 4 to help students acquire the different skills needed at different junction of their education journey.

R.E.A.L Learning Approach

Student Experience

Mastering chemistry can be difficult due to the topic progression. A lack of understanding in one topic would lead to a “snowball effect” making it difficult to fully master the other topics. Our combined science tuition classes focus on using a structured and systematic approach to build a strong foundation in the core combined science concepts that would ease the mastery of advanced chemistry topics.

Guaranteed Excellence

At Explorer Acade­my, we make it a priority to kee­p our classroom materials and note­s current and updated. We do this to align the­m with the latest O Level Combined Science syllabus and ensure we have the best O Level Combined Science tutors with the most e­ffective teaching me­thods. We found that this approach is particularly beneficial for our students who may find ce­rtain topics challenging. Our thoroughly curated resource­s can help create a solid foundation for the­se students. Joining Explorer Acade­my guarantees that students will have­ all the necessary tools to succe­ed. This success exte­nds far beyond Combined Science, preparing students for all future acade­mic ventures.

Our incredibly intelligent teachers are exceptionally skilled at turning those “I don’t get it” moments into joyous “Eureka! Now I understand” moments.

What Our Students Say

Testimonies and Reviews from our current and ex students.

Frequently Asked Questions (FAQ)

Are your classes online or physical?

All lessons are physical classes as we conduct activity and experiments in class to give students a better understanding behind each scientific concepts.

A physical class also provides more personalised interaction between students and teacher allowing teacher to identify each student learning needs quickly and use the most appropriate approach to guide them.

Exam Paper Review

Submit your school papers for review after each exam and together we spot strengths and learning gaps, decode tricky questions and exam techniques and plan what to focus on next term.

Every exam becomes a valuable learning opportunity

1-to-1
Clarity Consultation

A one-to-one consultation where teachers help students to set clear learning goals, receive targeted coaching on weak areas and map out an action plan for success.

It’s a personalised guidance that turns weaknesses into strengths.

SCI-CORE Profilier

A personalised progress summary highlighting strengths, areas to improve, and clear action steps for the term. Unlike school reports that come only at the end, ours is shared before major exams so students can act early. Parents may also book a call with the tutor to discuss the profile in detail.

It’s not just a report — it’s a roadmap to improvement.

SCI Masterclass

Focused revision sessions on key topics taught in the term. Each Masterclass reinforces understanding, sharpens mastery, and strengthens long-term retention that help students feel confident and exam-ready.



LAB + Experience

Our Secondary LAB+ help students gain confidence handling lab equipment, mastering practical skills, and preparing for Lower Secondary and O-Level practical exams.

For Primary levels, fun sensory experiments connect directly to classroom topics that builds curiosity, reinforcing scientific keywords, and processing skills and answering technique framework. Each child also receives a take-home lab kit to continue exploring Science beyond the classroom!

R.E.A.L Methodology

Recall → Explain → Apply → Link
Our step-by-step approach breaks tough concepts into simple, bite-sized parts. Using active recall and spaced repetition, students build stronger memory and deeper understanding.

Once students understand the concept, we guide them through the right thought process to apply their knowledge and connect ideas across topics. This helps them see the bigger picture and makes Science logical, meaningful, and easier to master.
