IGCSE Physics, Chemistry and Biology support for concepts and exam answers
Science students often need help connecting syllabus knowledge with the way marks are awarded. Support can focus on concepts, calculations, practical-style questions, command words, data interpretation and longer written answers.
Physics
Calculations, units, graph interpretation, electricity, forces, energy, waves and explanation structure.
Chemistry
Equations, bonding, energetics, rates, organic chemistry, practical interpretation, definitions and use of precise terminology.
Biology
Processes, key terms, data questions, experimental design, comparison questions and longer written explanations.
How Science support is scoped
Before recommending support, we check which science, exam board and paper style the student is preparing for. A broad request such as “Science help” is usually not enough to plan responsibly.
| Question | Why it matters | Typical next step |
|---|---|---|
| Separate sciences, combined science or coordinated science? | Topic depth, paper structure and revision priorities can be very different. | Confirm the route before choosing lessons or marking. |
| Which subject is most urgent? | Physics, Chemistry and Biology need different tutor strengths. | Prioritise the subject with the largest mark gap or nearest assessment. |
| Is the issue concept, calculation or wording? | A student may know the content but fail to express it in mark-scheme language. | Use diagnostic review or mock marking before a large package. |
| Are practical-style questions weak? | Planning, variables, graphs, data and evaluation can carry important marks. | Build a focused practical-skills block. |
Common Science mark-loss patterns
High marks usually require both knowledge and exam-board style. The answer has to be accurate, specific and linked to the question.
Vague explanations
Answers use everyday language instead of the specific scientific terms needed for credit.
Calculation errors
Students lose units, significant figures, rearrangement steps or graph-reading accuracy.
Practical questions
Variables, controls, reliability, safety, graph conclusions and evaluation are not explained clearly.
Data interpretation
The student describes a graph or table but does not explain the trend, anomaly or scientific reason.
Useful evidence before booking
Science support becomes much more accurate when the family shares evidence from the exact route.
- Subject route: Physics, Chemistry, Biology, combined science or coordinated science where relevant.
- Exam board and paper route if known.
- Recent mock, topic test, practical-skills question or teacher feedback.
- Questions where the student lost marks despite knowing the topic.
- Exam date, target grade and whether support is needed for one science or several.
Science situations families often describe
The first conversation is usually more useful when the family describes the mark pattern, not only the subject name.
| Family description | What we would check | Sensible first move |
|---|---|---|
| The student revises the textbook but still drops marks. | Whether answers are too general, miss command words or do not use enough scientific terms. | Mock marking from £45 or a diagnostic review from £35 to identify the answer habit. |
| Physics calculations keep going wrong. | Units, rearranging, significant figures, graph reading and whether the formula choice is secure. | Focused one-to-one lessons from £45 with short calculation practice between sessions. |
| Chemistry makes sense in class but not in exam questions. | Whether bonding, equations, rates, organic chemistry or practical wording is the real barrier. | Use a topic test or marked paper to choose the first block. |
| Biology answers are too short or too vague. | Whether the student can turn knowledge into precise sequence, comparison or explanation. | Written-answer correction before adding broad revision lessons. |
| The student takes combined science but is unsure what papers apply. | Exam board, route, paper codes and whether separate-science material is being used by mistake. | Confirm the route first, or use exam planning from £55 if several details are unclear. |
What strong Science feedback should do
Useful feedback does more than mark an answer right or wrong. It shows the student how to turn knowledge into marks on the next question.
Use the command word
Describe, explain, compare and evaluate need different answer habits.
Name the missing term
Students need to see which key term, unit or process step would have earned credit.
Connect data to science
Graphs and tables should lead to a reason, not only a description of the pattern.
Choose the next task
After feedback, the family should know whether the student needs concept teaching, calculation practice or written-answer correction.
Request Science support
Share which science subject is most urgent and upload a recent paper if available.
Recall, calculations, data handling and exam wording lose marks in different ways
Physics, Chemistry and Biology often need different support even when the family simply says “Science is weak”. The first step is to identify the paper style and the type of mark loss.
Subject and paper route
Confirm whether the student needs Physics, Chemistry, Biology, Combined Science or a specific paper route.
Calculation and unit evidence
Science scripts often show whether the issue is formula selection, unit conversion, significant figures or explanation.
Practical-style questions
Data, graphs, variables and method evaluation may need separate practice from content recall.
| What parents may see | What it may indicate | Service and price |
|---|---|---|
| Definitions are memorised but longer answers lose marks. | Command words and mark-scheme phrasing need work. | Mock marking or targeted lessons on explanation quality. |
| Calculation questions are inconsistent. | Formula use, units or multi-step reasoning may be weak. | Diagnostic review with topic-specific tutoring if repeated. |
| Graph or data questions cause mistakes. | Practical-style skills need deliberate practice. | Science tutoring or guided study with marked checkpoints. |
| Subject route or practical requirement is unclear. | Official school or centre rules may affect preparation. | Exam planning before lessons. |
Exam-route questions to confirm before payment
| What to confirm | Why it affects the purchase | Useful evidence to send |
|---|---|---|
| Separate science or combined science route | Physics, Chemistry, Biology and Combined Science can differ in content range and paper structure. | Exact subject, exam board, paper route and school course details. |
| Whether marks are lost in recall, calculation or explanation | Knowledge recall, formula work and longer answers each need a different training route. | Marked topic tests, mock scripts or teacher comments. |
| Practical-style or data-question requirements | Graphs, variables, method evaluation and data handling often need separate practice. | Relevant answers, school feedback and any official route questions. |
How this subject usually maps to the right service
| Student situation | Better first service | Purchase logic |
|---|---|---|
| Long answers and command words lose marks | Mock Marking or targeted lessons | Connect content knowledge to mark-scheme wording and explanation depth. |
| Calculations, units or graphs are inconsistent | Diagnostic Review before topic support | Identify the exact error pattern before paying for broader tutoring. |
| Subject route or practical requirement is unclear | Exam Planning | Confirm official route questions before paying for the wrong paper preparation. |
Official practical, centre or school requirements must be confirmed with the school, exam centre or exam board. We can support preparation but do not act as an official centre.
Separate Science recall, calculation, data and explanation errors
Physics, Chemistry, Biology and Combined Science can fail for different reasons. The first useful decision is whether the issue is content knowledge, method, practical-style data or exam wording.
| Skill area | What is checked | How support works | Sensible route |
|---|---|---|---|
| Knowledge recall | Definitions, key processes, diagrams and topic tests with marks or teacher comments. | Rebuild weak topics and connect facts to the wording students must use in answers. | Diagnostic Review £35 or targeted lessons from £45. |
| Calculations and units | Formula choice, substitutions, unit conversions, significant figures and multi-step working. | Teach formula selection, working layout and checking routines through marked examples. | Focused one-to-one support after the error pattern is clear. |
| Data and practical-style questions | Graphs, variables, method evaluation, tables and interpretation questions. | Practise graph reading, variable control, evaluation language and data explanation. | Guided Study from £179 or targeted Science tutoring. |
| Command words | Longer answers where the student knows content but misses explain, describe, compare or evaluate marks. | Turn knowledge into mark-scheme style answers without memorising generic paragraphs. | Mock Marking £45/£79 or lesson feedback. |
Science support can help preparation and interpretation of evidence. Practical requirements, centre rules and entries must be confirmed with the relevant official provider.
First identify which kind of Science marks are being lost
Science can mean Physics, Chemistry, Biology or Combined Science, and each student may need recall, calculation, data, practical-style or explanation support.
Send marked answers by subject
A Physics calculation issue is different from a Biology explanation issue, so the exact subject matters.
Reading notes may not fix exam answers
Many students know facts but lose marks because command words, units or data handling are weak.
Plan the route before teaching
If separate/combined route or practical requirements are unclear, exam planning should come first.
| Parent question | What to send or confirm first | Likely first step | Why this is safer |
|---|---|---|---|
| How do we know whether Science needs tutoring or marking? | Marked topic tests or mock answers with the exact science subject. | Diagnostic Review at £35 or Mock Marking at £45/£79. | It shows whether the issue is recall, calculation, data handling or explanation. |
| The student knows the content but loses long-answer marks. What helps? | Long answers with marks or teacher comments. | Targeted tutoring from £45 or mock feedback if a paper is complete. | The support can focus on command words and mark-scheme phrasing. |
| What if the route is separate science, combined science or private candidate? | School route, exam board and any centre questions. | Exam Planning at £55/£89. | Official route questions should be confirmed before buying lessons. |
| Can guided study work for Science? | Topic list, weekly availability and recent quiz or mock evidence. | Guided Study from £179 if the student can complete tasks between checkpoints. | It can be more efficient than live lessons when accountability is the main gap. |
We can support preparation and question practice. Official practical requirements, entries and centre rules remain with the school, centre or exam board.
