Question 1

How long does it take to memorise the IGCSE Chemistry vocabulary?

Accepted Answer

The honest answer is that it varies from student to student, and the Chemistry vocabulary in 0654 covers all 12 chapters (C1–C12), so there is a meaningful amount to learn across topics from states of matter right through to experimental techniques. The good news is that spaced retrieval makes this much more manageable: revisiting our flashcards in short, regular sessions means each term gradually moves into long-term memory, rather than fading after a single read-through. We'd suggest working through one chapter's flashcards at a time and cycling back to earlier chapters every few days, building up a steady rhythm rather than trying to cover everything at once.

Question 2

How many flashcards should I do a day?

Accepted Answer

There's no universal number that suits every student, but the research on spaced retrieval suggests that a short, consistent daily session beats a longer occasional one by a wide margin. We'd suggest starting with a comfortable batch of our flashcards each day and increasing gradually as your confidence grows. Since the Chemistry component of 0654 spans 12 chapters (C1–C12) alongside Biology and Physics content, our by-topic view is a great way to spot which areas need the most attention and weight your sessions accordingly.

Question 3

Should I make my own Chemistry flashcards or use Cognito's?

Accepted Answer

Making your own flashcards is a genuinely useful study habit, but for Cambridge IGCSE 0654 Extended Chemistry we'd suggest using our ready-made ones as your foundation so you're not spending precious revision time building resources from scratch. Our flashcards cover all 12 Chemistry chapters (C1–C12) in the syllabus, so you can be confident the full Extended content is there.

A great hybrid approach is the blurt technique: read a card, close it, and write down everything you can recall, then check what you missed and annotate or add your own cards for any gaps. This way you get the active-recall benefits of creating your own cards without the risk of accidentally leaving out a topic.

Our by-topic view also makes it easy to focus your flashcard sessions on whichever chapter needs the most attention.

Question 4

Which Cambridge International Chemistry topics are flashcards best for?

Accepted Answer

Flashcards shine brightest on the definition-heavy and list-heavy areas of Chemistry, where AO1 knowledge recall accounts for 50% of your Cambridge International marks. Topics like C2 (atoms, elements and compounds), C7 (acids, bases and salts), C8 (The Periodic Table) and C9 (metals and the reactivity series) are packed with precise terminology, sequences and properties that respond really well to spaced retrieval. C4 (electrochemistry), C5 (chemical energetics) and C6 (chemical reactions) also carry a lot of key definitions, such as oxidation, reduction, activation energy and catalyst, that are satisfying to test yourself on one card at a time. Our flashcards are organised by topic across all 12 Chemistry chapters, so you can focus on whichever area feels shakiest and build your recall at a steady pace.

Question 5

Why do I keep forgetting IGCSE Chemistry vocabulary?

Accepted Answer

Forgetting Chemistry vocabulary is really common, and it usually comes down to passive reading rather than active recall. When you read through your notes without testing yourself, your brain treats the information as familiar without storing it deeply enough to retrieve under pressure.

Our flashcards are built specifically to fight this, using spaced retrieval so that terms like "electrolyte," "activation energy," or "oxidation number" come back to you at exactly the right interval before you forget them. Each time you retrieve a definition successfully, the memory trace strengthens, and each time you stumble, the card reappears sooner so you can close the gap.

We'd suggest working through the flashcards little and often rather than doing long single sessions, since shorter, more frequent practice sessions spread across the week make vocabulary stick far more reliably than a last-minute cram.
