Class size
Maximum 4 students
Students are grouped by learning pace, not just by level — if no existing session matches your child’s pace, we open a new one.
Class registration for the 2027 school year is open.
Sec 4 IP Chemistry tuition
Our tutors help Sec 4 IP students work through multi-step calculations, explain unfamiliar data and review experimental methods. Lessons use the school’s assessment scope and recent feedback to choose revision topics.
Live online classes · Maximum 4 students · 1.5 hours weekly
Preparation guided by the next school assessment
- Combine equations and quantities across several steps
- Identify limiting reagents and justify assumptions
- Use unfamiliar tables and graphs as evidence
- Review experimental methods and the limits of a conclusion

The school sources below describe their IP programmes. Use your child’s current topic list and assessment scope to plan lessons.
Study guide · 01
Plan the calculation before starting
Start with the quantity requested and work back to the information needed. Write the relevant balanced equation, identify the available quantities and decide whether a reagent is in excess. A mass measurement may first need conversion to moles; a solution calculation may require a volume conversion. Keep the substance attached to every value.
When more than one starting amount is given, compare each with the equation’s coefficients. The smaller numerical mass or amount is not automatically the limiting reagent. State how much of the other reagent would be required to use it up. This comparison also checks whether an assumption of excess is justified.
After calculating, interpret the answer. Check its units and whether the amount could physically arise from the starting material. If a question gives a measured yield, distinguish the theoretical amount from the experimental result. A lower measured yield needs an explanation tied to the method; it is not by itself proof that the equation was wrong.
The task
For Mg + 2HCl → MgCl₂ + H₂, a mixture contains 0.030 mol Mg and 0.040 mol HCl. Assuming the reaction proceeds to completion, find the amount of H₂ formed.
Worked response
Reacting all 0.030 mol Mg would require 0.060 mol HCl. Only 0.040 mol HCl is present, so HCl is limiting. The HCl:H₂ mole ratio is 2:1, giving 0.020 mol H₂. This consumes 0.020 mol Mg and leaves 0.010 mol Mg.
Comparing the reactants against the balanced equation establishes the limiting reagent before calculating the product. The remaining magnesium provides a consistency check. No gas-volume conversion is needed because the question asks for an amount in moles.

Read the data before choosing an explanation
Read the table headings, graph axes, units and conditions first. Identify the comparison the question actually permits. A larger final gas volume may concern the amount of product; a steeper initial gas-volume curve concerns rate. Those are different claims, even when they appear on the same graph.
State the pattern with a comparison from the data, then explain it using the relevant chemical idea. If two experiments differ in several conditions, say which uncertainty prevents a stronger conclusion. Do not invent a numerical result or treat a trend outside the measured range as established.
For questions asking students to evaluate a method, connect a proposed change to the specific limitation. Repeating readings can help assess random variation; it does not automatically remove a systematic offset. Discuss how the error would affect the quantity measured and whether the conclusion could still be supported.

Use school assessment feedback to choose the next practice
Find out why an answer was wrong. Did you forget a fact, misread the question, choose the wrong equation or leave out an explanation? Review a forgotten definition; practise choosing the calculation method if the formula was used in the wrong situation.
After working on a difficulty, mix topics so you have to choose the method. Then try timed sections and check for rushed reading or missing units. Use the school’s assessment instructions for the scope and format.
Our tutors use recent work to plan live lessons and follow-up subject practice. Share the school’s current topic list and assessment scope so practice targets the next assessment.
Where schoolwork reveals a gap
Familiar facts in an unfamiliar setting
A question supplies a new substance or process. Students need to identify which familiar principle applies and explain why.
Working that hides an assumption
Students check whether the question states that a reagent is in excess and which gas-volume conditions to use before calculating.
How we support the school course
Read the task and feedback together
We use the current topic list, assessment scope and teacher comments to choose what to practise.
Explain each step
Students explain how the diagram, equation or data helps them answer the question.
Try another set of conditions
We change the conditions or values and ask the student to explain whether the same method still applies.

A trial class lets your child meet the teacher, take part and see how the lessons work.
Frequently asked questions
Clear answers for parents
How many students are in each class?
Four, at most. Students are grouped by learning pace, not just by year level, so each lesson moves at the speed of the students actually in it. When no session matches a child’s pace, we open a new one. In a class that size, every child answers questions, gets their working checked, and gets help the moment they need it.
How much does a dedicated trial session cost?
A dedicated trial session at a different timeslot is offered at a subsidised rate of $30. We’ll help you explore the available options.
Do you prepare students for their school’s Sec 4 IP assessments?
Yes. We use the school’s current assessment scope, assignments and teacher feedback to choose what to practise.
Should every revision session be a timed paper?
Short exercises give you time to work on a mistake. Mixed questions test which method you choose, and timed sections check pace. Use all three rather than repeating full papers without reviewing the errors.
What should we bring to a Sec 4 IP Chemistry trial?
Bring a recent assignment or assessment, including the student’s working and teacher feedback, together with the school’s current topic list.
Is registration open for 2027?
Class registration for the 2027 school year is open. Request a trial class using the form. We will message you to confirm your child’s 2027 level and class details.
Is practice included?
Yes. Students practise on DeepThink between their weekly live online lessons.
