JC2 H2 students

Issues faced by JC2 H2 students

JC 2 is a critical year for students as they are sitting for their crucial ‘A’ Level examinations in preparation for their entry to University. The concepts learnt in JC 2 is constructed on the essential foundational topics built up in JC 1. Topics are increasingly inter-linked and failure to master earlier content leads to accumulation of weak concepts that snowball, leading to the child being lost in many of the subsequent chapters.

Students are often daunted by the learning of Organic Chemistry which is a massive chapter spanning 10 topics. They find that they are no longer able to apply rote learning and memorisation techniques. Instead, they need to have a in-depth understanding of how the various functional groups can converted from one to the other as well as a mechanistic understanding of what Organic Chemistry is about in order to tackle the higher order thinking questions.

Students also face increasingly complex application questions which require them to understand the subject matter completely and be able to extend concepts to new, novel situations.

In addition, they face an intimidating task in their practical examination to complete 3 tedious experiments accurately and precisely in a short time span, while juggling the analysing and evaluation of their data as well. The 4 papers is a hefty task, and students who are unable to withstand the load often buckle under the pressure.

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.

Syllabus outcomes

This curriculum framework provides students the opportunity to appreciate the connections between the concepts in the Core Ideas of Matter, Structure and Properties, and Transformation, and to apply these to the study of different chemical systems in the Extension Topics: Organic Chemistry, Electrochemistry and Transition Elements Chemistry.

Although there are features of organic chemistry topics that are distinctive, it is intended that appropriate cross-references with other sections/topics in the syllabus should be made. In their study of organic chemistry, candidates may wish to group the organic reactions in terms of the mechanisms in the syllabus where possible. Candidates may wish to compare and contrast the different mechanisms. Modern organic chemistry is based on the concept that the four valence bonds of a carbon atom are oriented in a tetrahedral configuration, which led to the development of the stereochemical concept. This has important applications, particularly in the pharmaceutical industry as many drugs are active only in one particular enantiomeric form.

2. Hydroxy Compounds

3. Carbonyl Compounds

4. Carboxylic Acids and Derivatives

5. Nitrogen Compounds

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). For aqueous redox reactions, the more convenient notion of electrode potential (E) is used, and the resultant cell potential (Ecell) gives a measure of thermodynamics feasibility instead.

6. Electrochemistry

7. An Introduction to the Chemistry of Transition Elements

8. Solubility Equilibrium

At A-Level, an in-depth study of the electronic structure of atoms provides the basis for the study of chemical bonding, which determines the type of interactions possible and also helps to explain the physical and chemical properties. Knowledge of structure and bonding is also important to study and predict trends in properties of matter and its reactions.

Get Answers to Your Questions

How are lessons like?

We will always start a chapter with a lecture. Notes will be handed out to students. Our notes are known to be top-notch – comprehensive, clear, concise and well structured. During the lecture, the emphasis is on content training and understanding of concepts.

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. 1) Online content lessons (these are recorded as well to allow students to watch at this own time and pace)
  2. 2) Online consults
  3. 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?

We offer multiple time slots for the same level within the same week. The lessons are repeated and exactly the same. No stress when you cannot make it for your usual slot, there is always a make-up class available for you.

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:

  1. You may purchase our Chemistry Masterclass videos at a discounted rate, followed by a consultation session to clarify any questions that you may have.
  2. 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.
