O Level Chemistry Tuition for the 2025 Exam | 80% Distinction

Our specially crafted study materials are designed specifically for chemistry students taking O-Level exams. These materials are not just informative but are tailored to make students’ learning experience engaging and effective, helping them score an A grade in their examinations.

We understand that practice is key to success. That’s why we provide our secondary students with access to a wide range of “cheat sheets” and model answers, allowing them to familiarise themselves with the exam format and a lot of question types.

We offer comprehensive revision guides and resources to help students prepare effectively for their O-Level examinations. Our guides are succinct and easy to understand and cover essential topics, provide in-depth explanations, and offer valuable tips and strategies to excel in exams.

To ensure that every student is fully prepared for their O-Levels, we offer some of the best, most flexible intensive revision programmes that focus on key subject areas and provide targeted practice sessions. These programmes help students build confidence and hone their skills, leading to better performance in their exams.

Success in O-Levels isn’t just about knowledge; it’s also about having effective study strategies and exam techniques. Our experienced tutors are patient and dedicated to imparting these strategies to our students, helping them approach their exams with confidence and precision.

Choosing the right path after O-Levels is a crucial decision, whether it’s Junior College (JC), Polytechnic or other options. At Zenith, our expert advisors assist students in navigating the requirements, strengths, and long-term implications of each post-secondary route. From subject combinations in JC to course selection in Poly, we provide insights that help you and your family make informed, future-ready choices – especially for those planning to specialise in H2 Chemistry or pure chemistry programmes. With Zenith, students don’t just get academic support — they gain the guidance needed to take confident next steps in their educational journey.

Students will need to answer 40 compulsory multiple-choice questions within 1 hour. This paper accounts for 30% of the students’ grade and requires rapid recall across all the topics they have studied, averaging around 1.5 minutes per question.

Students will be required to complete two sections (Sections A and B) within 1 hour and 45 minutes. Making up 50% of their grades, this paper tests students’ ability to handle information and solve problems, while also testing the depth of their understanding of each subtopic. 

Section A will consist of a variable number of compulsory structured questions carrying a total of 70 marks. The last two questions in particular will carry 20 marks, with the majority being allocated to a data-based question. Section B will include two questions, of which candidates should choose only one to answer. This question is worth 10 marks.

Students will need to prepare a practical experiment based on the instructions given, and answer multiple experiment-related questions within 1 hour and 50 minutes. This paper accounts for 20% of thestudents' final grade. It aims to assess their practical abilities, including planning appropriate chemistry experiments to test a hypothesis and handling lab apparatus correctly.
