One weak IGCSE grade beneath several secure results deserves investigation before extra lessons begin. The outlier may reflect a precise gap in knowledge, exam technique, timing, confidence, or preparation, and the right support depends on finding which one.
At 7:20 on results morning in Accra, Ama stood at the dining table with her son Kojo’s results sheet open on her phone. His English, mathematics, and business grades matched the range his teachers had expected. Then she reached the final line: chemistry. The grade sat two levels below the others.
This is an illustrative composite, but the dilemma is familiar. Kojo wanted to continue with science, and his next subject choices were approaching. If the grade reflected weak foundations across chemistry, choosing the next course could leave him struggling from the first term. If the result came from one narrow problem, dropping the subject could close an option he was still capable of pursuing.
Ama’s first impulse was immediate: book more chemistry lessons. She paused before doing so.
Start with the shape of the result
A single low grade tells you that something went wrong. It does not tell you what.
Look first at the wider pattern. Did the student perform securely in subjects that require similar skills? A learner who writes clear explanations in biology but loses marks in chemistry may understand scientific ideas while struggling with chemical equations, calculations, or subject-specific vocabulary. A student whose grades fell across several timed papers may need help with pacing or exam conditions rather than one isolated topic.
Then compare the result with evidence from before the examination:
- Were school assessments consistently stronger?
- Did recent exercise books show unfinished topics or repeated corrections?
- Were practice papers completed within the allotted time?
- Did the student leave sections blank?
- Was there a large gap between what the student could explain aloud and what appeared in written answers?
These questions turn a disappointing line on a results sheet into a set of testable possibilities. They also prevent one grade from becoming a verdict on the student’s ability.
A broad national or school-level pattern can provide context, but it cannot diagnose one learner’s needs. Your child’s own work should guide the next decision.
Find the point where marks began to disappear
Ama and Kojo returned to his chemistry materials that evening. They did not begin by rereading the entire syllabus. They placed two marked practice papers beside his exercise book and looked for repetition.
Kojo could describe the science in conversation. On paper, however, his longer answers often stopped one step early. He named a process but did not connect it to the observation in the question. In calculations, he sometimes wrote the correct method and lost track of a unit near the final line.
The weak result still mattered. Its meaning had become narrower.
This distinction changes the intervention. A student with missing foundational knowledge may need carefully sequenced teaching across several connected topics. A student who knows the content but fails to convert it into marks may need worked examples, timed practice, and direct feedback on how answers meet the demands of each question. The difference is explored further in What If My Child Knows the Content but Cannot Turn Evidence Into Marks?.
The investigation should also include the student’s account. Ask what felt difficult while the paper was in front of them. Which section consumed too much time? Which wording caused uncertainty? Did they change correct answers after doubting themselves? Keep the conversation specific and calm. “Show me where it became difficult” produces more useful information than “Why did you do badly?”
Match support to the actual gap
Once the likely cause is clearer, define a short first objective. Avoid goals such as “improve chemistry” because they provide no way to judge whether the support fits.
A useful objective might be completing mole calculations with correct units, planning six-mark responses before writing, or finishing a selected paper section within its time allowance. The tutor can then see the student working, identify where the reasoning breaks, and adjust the lesson around evidence rather than assumptions.
Curriculum fit matters here. Cambridge IGCSE has its own syllabus content, command words, assessment structure, and expectations. A tutor who understands the relevant curriculum can connect subject teaching to the way the student will need to demonstrate knowledge in the examination.
For Ama, this was the turn. With subject choices still unsettled, Kojo completed focused work on calculations and extended responses instead of restarting chemistry from page one. The next conversations could now use his written work as evidence. Keeping science remained possible, but it would be a considered choice rather than a reaction to one painful morning.
Give the outlier a review date
Set a point to review the evidence after a defined block of work. Use a comparable task, such as another timed section or a set of questions targeting the same skills. Check whether the original errors have changed.
If the student now completes the method accurately but still runs out of time, pacing becomes the next priority. If the same conceptual gap remains, the teaching sequence may need to move further back. If performance improves across several attempts, the family has stronger grounds for confidence.
Weeks later, Ama’s dining table held a different kind of evidence: two completed chemistry sections, corrections written beside the lost marks, and a subject-choice form waiting nearby. The original grade had not disappeared. It had stopped being the only information in the room.
