Top 4 Common GCSE & IGCSE Maths Mistakes Students Make (and How to Avoid Them!!)

Dec 23, 2025 | Shannon Tanwani | IGCSE/ GCSE Maths

GCSE and IGCSE Maths exams often test more than just knowledge - they test accuracy and the method. Many students lose easy marks due to common repeatable mistakes rather than a lack of understanding.

Below are the most common GCSE and IGCSE Maths mistakes and practical ways students can avoid them.

 

👉#1: Misreading the Question

It’s one of the most common mistakes students make. Rushing through a question often leads to missed details such as units, key command words, or clues that indicate how the problem should be solved.

✅How to avoid it: Learners Cloud Maths videos are clearly structured and guide students through each steo of the process. Students can read, interpret, pause, and solve questions alongside the teacher on screen, reinforcing correct exam technique and improving accuracy.

 

👉#2: Memorising Formulas Without Understanding Them
Knowing the formula isn’t enough if students don’t understand when and why to use them - whether it’s a speed, distance, time equation [insert link to video], or a basic unit conversion [video here]. 

✅How to avoid it: Learners Cloud focuses on concept-based Maths explanation videos, helping students understand the logic behind formulas so they can apply them confidently across different GCSE and IGCSE questions.

 

👉#3: Losing Method Marks in Multi-Step Questions

GCSE and IGCSE maths exams reward clear working. Skipping those steps can result in losing valuable marks.

✅How to avoid it: Learners Cloud UK’s videos model clear, exam-ready and curriculum aligned working methods, helping students maximise marks even if the final answer is incorrect.

 

👉#4: Not Understanding Exam Language

Key terms like calculate, show, and explain often confuse students and lead to incomplete answers.

✅How to avoid it: Exam-style walkthroughs help students become familiar with GCSE & IGCSE Maths command words and examiner expectations.

 

Remember, most GCSE and IGCSE Maths mistakes are avoidable with the right approach and consistent practice.
