Question 1

How long does it take to memorise the A-Level Chemistry vocabulary?

Accepted Answer

There's no universal timeline, it depends on your starting point and how much time you spend with the material each day. If you're using our flashcards regularly (say, 20–30 cards a day with spaced repetition), you could build familiarity with the core vocabulary within a few weeks, but real fluency takes longer. Most students find that active recall across the full two-year course helps the terminology stick for exams.

We'd suggest starting early and revisiting the cards in short sessions rather than cramming, that's what makes the difference between recognising a term and being able to use it fluently under timed conditions.

Question 2

How many flashcards should I do a day?

Accepted Answer

We'd suggest starting with 20–30 flashcards a day. That's enough to build the habit and see progress without feeling overwhelmed. As you get more comfortable with the routine, you can gradually increase the number, some students work up to 50 or more, but what matters most is consistency.

Little and often beats cramming, so even 15 minutes a day will help the content stick. If you're revising an A-Level topic you studied weeks ago, you'll probably breeze through more cards than when you're first learning new material, so adjust based on how confident you're feeling.

Question 3

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

Accepted Answer

We'd suggest using our flashcards rather than making your own. Our set covers every reaction, every concept, and every core practical from the 9CH0 spec, so you can be confident nothing's missing. Making your own cards can be a useful technique (it forces you to decide what's important), but it's time-intensive and you risk leaving out key details or misrepresenting tricky concepts like ligand geometry or electrode potentials.

A good middle ground is the blurt technique: use our flashcards to test yourself, then close the app and write out everything you remember on paper. That way, you get the retrieval practice without the hours spent creating cards. Once you've blurted, check what you missed and focus your next session there. This approach saves time and keeps your revision tight on the spec content you'll be tested on.

Question 4

Which Pearson Edexcel Chemistry topics are flashcards best for?

Accepted Answer

Flashcards work brilliantly for any topic where you need to lock in definitions, learn formulae, or recall key reactions. In Edexcel A-Level Chemistry, that means they're especially useful for **bonding types and structures** (Topic 2), **redox** (Topics 3 and 14), **organic chemistry** (Topics 6, 17 and 18) and **transition metals** (Topic 15), anywhere you're learning new terminology or reaction schemes that need to stick.

They're also great for **energetics** (Topics 8 and 13), where you can drill equation structures and calculation steps, and for **periodic trends** (Topics 1 and 4), where patterns in ionisation energy or reactivity need active recall. For topics like **equilibrium** (Topics 10 and 11) or **acid-base equilibria** (Topic 12), flashcards help you rehearse key expressions and concepts before you move on to full calculations.

You'll find all our flashcards organised by-topic, so you can target exactly what you need. We'd suggest starting with the definitions and core reactions, then layering in the mechanisms and calculations as you build confidence.

Question 5

Why do I keep forgetting A-Level Chemistry vocabulary?

Accepted Answer

Forgetting vocabulary is completely normal when you're learning A-Level Chemistry, it happens because our brains need repeated exposure to new terms before they stick. The good news is that you can fix this with spaced retrieval: instead of cramming all the words in one go, revisit them in short bursts over several days or weeks. Our flashcards are built for exactly this, they bring each term back at the right moment so your brain can lock it in without extra effort.

Try 10–15 cards a day, and you'll notice the difference within a week or two.
