JC1 H2 Chemistry Tuition
Issues faced by JC1 H2 chemistry students
Concepts are a lot more in-depth and require an excellent understanding of the subject matter in order to solve many of the harder application questions.
Students can no longer apply rote learning techniques which they picked up in secondary school. Besides knowing the key words to answer questions accurately, students must also be able to recognise the myriad of ways that a similar concept can be applied, especially for higher order thinking questions.
Students are also often careless when attempting MCQ questions and get tricked by common pitfalls placed by examiners to trap them when they do not have a firm grasp of the foundational concepts. They also exhibit poor time management, leading to insufficient time to complete the examination.
Chemistry is about the study of matter, its interactions and transformations. At a macroscopic level, we observe matter and its interactions everywhere in our daily life. The submicroscopic level looks at the structure of matter that gives rise to these interactions. At O-Level, students have been introduced to the fundamental idea that matter is made up of particles and the simple atomic model (electrons in discrete shells around a positively charged nucleus). This allows students to apply the key ideas of conservation of matter and energy in the quantitative treatment of reactions such as stoichiometry and thermochemistry.
At A-Level, an in-depth study of the electronic structure of atoms provides the basis for the study of chemical bonding. The Valence Shell Electron Pair Repulsion (VSEPR) model is used to visualise the three-dimensional structure of molecules, which determines the type of interactions possible and also helps to explain the physical and chemical properties.
Transformation of matter involves the study of the feasibility (thermodynamics and kinetics considerations) and extent of chemical reactions (concept of equilibrium). The chemical thermodynamics dimension builds upon prior knowledge of thermochemistry, mainly enthalpy changes (∆H). Together with entropy changes (∆S), a mathematical relationship is established which gives the true measure of the thermodynamics feasibility of a reaction – the Gibbs free energy (∆G).
The concepts in chemical thermodynamics and kinetics will form the basis for the study of Chemical Equilibrium. Theoretically all reactions are reversible, and the notion of dynamic equilibrium will be introduced. The concept of equilibrium constant (K) is understood via the equilibrium expression, which gives a measure of the extent of a reversible reaction. Factors which determine the position of equilibrium will also be examined. Chemical equilibria in aqueous media involving acids and bases will be dealt with in greater depth, in view of the relevance and prevalence of these concepts which cuts across chemical systems.

How are lessons like?
Lessons are fun, engaging and inspiring. Misconceptions that have eluded you will be debunked; tips and tricks will be shared. Minimise your memory work, experience a quantum jump in your level of understanding, and most importantly, go home feeling satisfied and tons smarter. No one gets lost here.
We will follow up with a tutorial session to close the chapter. Tutorials are crucial in linking up theory and application. We will first look at worked examples to give you ideas on how to approach a question.
Do you offer online lessons?
We are redefining how Chemistry tuition lessons should be taught. Instead of simply seeing your child once a week for 2 hours, we endeavor to provide greater support for your child’s learning through closer guidance 2-3 times a week at no additional charge!
Adaptation and flexibility is the essence as we navigate through this new era of learning. In order to help your child more effectively, we are employing a 3-pronged approach:
1) Online content lessons (these are recorded as well to allow students to watch at this own time and pace)
2) Online consults
3) Physical consults
For students who prefer a more traditional approach, we have sessions with physical teaching as well.
What happens if I cannot make it for a lesson?
Video-recorded lessons are also available for viewing for students who miss the entire week of lessons.
What happens if I join the class late and need help for topics that have already been covered?
We always have new students coming in who may need help for previously-taught chapters.
You can choose from either of the following:
- You may purchase our Chemistry Masterclass videos at a discounted rate, followed by a consultation session to clarify any questions that you may have.
- We will run crash courses every school holiday to readdress all the major chapters that were previously taught. You may want to attend the crash courses during the March, June and September school holidays to catch up on previously-taught chapters.
