All Study Hacks ⬇️

How to actually use Past Papers

Do past papers under timed conditions, in one sitting, with no notes.
Mark yourself using the official marking scheme, be brutally honest. Keep track of where you lost marks in a seperate piece of paper.
Focus 80% of your revision on the topics/questions where you lost the most marks.

Why it's so useful: IGCSE repeats question styles. The more papers you do, the more you "predict" what's coming. You train your brain to recognize patterns and manage time under pressure.

Hacking Sciences (Biology, Chemistry, Physics)

Create a list of key scientific terms for each topic, then practise using them in sentences.
Memorise definitions exactly as they appear in the syllabus.
Practise drawing and labelling key diagrams: cell structures, circuits, human organs, chemical apparatus. Cover the labels and redraw from memory.
Include a brief explanation of each part's function.
For required practicals, know: aim, method, variables (independent, dependent, controlled), equipment, safety precautions, and expected results.
Write out the method in your own words.

The Leitner Method

Make flashcards for key terms, formulas, and definitions.
Use 3 boxes, with Box 1 (review daily), Box 2 (review every 3 days), Box 3 (review weekly)
Move cards up when you get them right. Move them back down when you get them wrong.

Why it's so useful: It combines active recall with spaced repetition, so you spend more time on what you don't know and less on what you do. It's efficient and science-backed!

The "Youtube Channel" Method

Pick a topic. Explain it out loud to your "viewers" like you're a youtuber livestreaming.
Use plain language and use analogies, Imagine that you can't mess up, otherwise you lose subscribers.
If you get stuck, that's your weak spot, then go back and review.

Why it's so useful:

If you can't explain it simply, you don't understand it well enough. This hack exposes gaps in your knowledge instantly.

Chunking Technique

Break big topics into smaller "chunks" (3-5 pieces per chunk)
Memorize one chunk at a time. Then connect the chunks together
For example: Instead of memorizing a 10-step process, memorize 2 steps at a time. (Eg. Common for Biology Unit 4/5)

Why it's so useful:

Your short-term memory can only hold about 4-7 items at once. Chunking organizes information into manageable pieces, making it easier to store and recall

The "Cheat on your Subject" Method

Instead of studying one subject for hours (block practice), switch between different topics or subjects in one session
For example: 30 minutes of math, then 30 minutes of English, then 20 minutes of science. (Tailor it to your schedule)

Why it works:

Interleaving forces your brain to differentiate between concepts and apply the right approach to each problem. This builds stronger connections and helps you adapt to unexpected questions.

This improves problem-solving skills and helps you adapt to unexpected questions, crucial for IGCSE exams.

All in One Method

After studying a topic, grab a piece of scrap paper and write a 1-page summary from memory.
Do not use your notes or textbook, just strictly what you remember.
Check your summary against your notes, then Fill in the gaps.

Why it's so useful: Summarizing forces active recall and reveals what you've actually learned versus what you think you've learned. It's a fast, effective review tool for IGCSES.

English Lang & Lit

Every body paragraph must follow PEEL: Point, Evidence, Explanation, Links Use this structure for every essay paragraph.
IGCSE markers love clear structure. PEEL ensures your essays are organised, persuasive, and easy to follow. You write faster and score higher.
For unseen poetry, start with the title. What does it suggest? Identify one key image, one key word, and one key technique. Analyse them.
Always link back to the question.

Syllabus Scanning

Print the official syllabus for each subject.
Highlight every topic green (know it), yellow (sort of know it), red (don't know it)
Revise ONLY red topics first

Why it's so useful: Most students waste time revising what they already know. The syllabus tells you exactly what you need to learn—and what you don't. It's the ultimate cheat sheet.

Mastering Geography

For each topic, memorise 2-3 case studies. For each case study, know: location, causes, effects, responses, and key statistics.
Write a one-page summary for each case study.

Practise drawing key diagrams: weather systems, population pyramids, plate boundaries, river profiles. Add labels and brief explanations.Practise explaining processes using your diagrams.
When analysing sources, use the 4 C's: Content, Context, Purpose, Limitations.

Content: What does it say?

Context: Who made it? When? Why?

Purpose: Why was it created? Who was the audience?

Limitations: What does it not tell you?

Business Studies and Economics

Create a glossary of key terms for each topic and define each term in your own words.
Practise using them in context eg. "How would inflation affect a business?"
For each business concept (e.g., marketing mix, financial ratios), memorise the key components.
Practise applying them to case studies in past papers
In exams, always link your answers back to the case study provided!!
Use specific details from the case study (names, numbers, locations)
Avoid generic answers that could apply to any business (Eg. This means the business will have more profit)

Mathematics

Create a single sheet with every formula you need to memorise.
Write it out from memory once a day
Highlight the ones you keep forgetting and focus on them.
Do past papers in timed conditions, and Mark yourself using the mark scheme. (Scrictly!)
Identify the 3 topic areas where you consistently lose the most marks, then prioritise revision on those topics.
IGCSE Maths has predictable question styles, and past papers reveal patterns. Target your weak areas for maximum improvement!
In long questions, write every step, even if it seems obvious.
Use clear notation and line-by-line working.

IGCSE exams test not just knowledge, but application, analysis, and technique. These hacks give you the tools to perform at your best. Practise them in your mocks. Trust them on exam day. YOU CAN DO THIS!!
