Learn it. Test it. Play it. Remember it.
Reading something once isn't enough. The way to remember it for the exam is to keep pulling it back out of your head. So every Chemistry lesson comes with lots of fun ways to do exactly that.
Learn
A 30-minute lesson on one part of the specification, with pictures, videos and clear explanations.
Test
A quiz straight after shows what's gone in, with the right answer the moment you get one wrong.
Play
Lemonaire and Last Stand turn the same lesson into a game, so you answer the questions again (and again) because you want to win.
Remember
Flash cards bring each idea back just before you'd forget it, until it's locked in for the exam.
Every question, card and game is written from the lesson, so it all follows the AQA 8462 specification. No random trivia.
Who Wants to Be a Lemonaire?
Lights, music and a host who talks to you. Zane Zest asks questions on the lesson you've just done, and you climb the Lemon Tree to a million lemons. Use 50:50, Phone a Friend or Ask the Audience if you're stuck.
Why it's fun
- A proper quiz show studio with a theme tune
- Three lifelines and a phone-a-friend
- Take the lemons or risk it all
- Beat your best score
How it teaches
- Every question comes from the lesson
- Starts with true or false, then builds up to four options
- Get one wrong and Zane shows the line from the lesson that explains it
Last Stand: they want brains. Use yours.
A 3D tower defence game. Build gun towers, snipers and tesla coils to stop the horde reaching your bunker. The catch? The scrap you build with comes from answering questions on the lesson.
Why it's fun
- A 4-level story with survivors and a boss
- Airstrikes, orbital lasers and flashbangs
- Recruit, Soldier and Veteran levels, with 3 stars to win
- Blitz mode for a quick 2.5-minute game
How it teaches
- Knowing the lesson is how you win
- "Urgent intel" questions pop up mid-battle against the clock, like exam pressure
- Wrong answers show the right one, so you learn as you play
Flash cards that actually test you
Not just flip and forget. Pick how tough: flip and rate yourself, read a clue and type the key word, or explain it in your own words and have it marked.
Why it's fun
- Points, streaks and lives
- Quickfire against the clock, or Endless with 3 lives
- Chilled lo-fi study music
- Swipe through them on your phone
How it teaches
- Pulling an answer out of your head (active recall) is one of the best ways to remember
- Cards you miss come back until you've got them
- Smart Review brings cards back after 1, 3, 7, 16 and 35 days, just before you'd forget
Check it's gone in, straight after every lesson
Every lesson ends with its own quiz. Pick 12 or 25 questions, Quickfire against the clock, or Endless until you run out of lives.
Why it's fun
- Points, streaks and sound effects
- Easy, Medium or Hard
- Stars for your best score
How it teaches
- You find out what you don't know straight away
- The longer modes mix in earlier lessons from the same topic, so older ideas keep coming back
The tricky topics, turned into 3D games

Carbon Clash
Build diamond and graphite atom by atom with a carbon gun, then drill, slide, wire up and heat what you built to see how four bonds in 3D or three bonds in flat layers decide hardness, slipperiness, conductivity and melting point
Play now
Free to play
Ghost Gas
The balance seems haunted, but it is gas: call whether the reading goes up, down or stays the same from the equation, then scan the gas molecules as they join a hot metal or escape from open crucibles and flasks, and seal a flask to prove mass is conserved
Play now
Free to play
Leftovers
Cook reactions in the Reaction Kitchen: draw a loop round one full recipe set of particles at a time until a reactant runs out, predict which one is the limiting reactant, change grams to moles, work out the mass of product and see why more excess makes no extra product
Play now
Free to play
Top Metal
Build the reactivity series on Reactivity Hill: duel metals in cold water and dilute acid, judge the fizz and climb each metal past the ones it beats, then knock less reactive metals out of their compounds, spot oxidation and reduction, and work out the order of mystery metals from experimental results
Play now
Free to play
Last Drop

Free to play
Discharge!
Ions race to the electrodes of an electrolysis cell: discharge the winner at each one (hydrogen or the metal, oxygen or the halogen), let the other ion go, test the gases and survive rush hour
Play now
Free to play
Over the Top!
Every ride is a reaction profile: give the reactants enough energy to get over the activation energy hill, build exothermic and endothermic profiles, draw the arrows and add a catalyst
Play now
Free to play
Hit Rate
Be a reacting particle: hit the other reactant with at least the activation energy, then change the concentration, gas pressure, surface area and temperature and watch the collisions get more frequent, more energetic or both
Play now
Free to play
Boiling Point
Run the valves on a cutaway fractionating column: heat the crude oil, watch each hydrocarbon rise, cool and condense on the first tray cooler than its boiling point, and catch every fraction
Play nowChain Reaction
Be the growing end of a polymer chain: swallow monomers as their C=C bonds open, dodge the alkanes, then draw the repeating unit with its brackets and n and work back to the monomer
Play nowSpot On
Run paper chromatography yourself: take the paper out just before the solvent reaches the top, measure Rf values, catch a banned dye and test whether a dye is pure
Play nowCase Closed
Run flame tests and precipitate tests on unknown solids, read the colours, then accuse the metal ion and the negative ion with proof
Play nowHeat Trap
Be the radiation: pass through the air as short wavelength, then escape as long wavelength while greenhouse gases absorb you and the human sources of carbon dioxide and methane pile up
Play nowWaterworks
Lay glass pipes from rivers, boreholes and the sea through filter beds, sterilising and desalination, then watch what reaches the tap
Play nowHaber Hustle
Run an ammonia plant: hold the temperature and pressure, use the iron catalyst, cool and recycle, and find the compromise that makes the most profit

Play nowReviews for Brainy Lemons
Real feedback from parents and students learning with Brainy Lemons.
“We have used you for Marine Science and Geography IGCSE subjects. We were very pleased with both the cost and ease of use of your online learning. We are very happy with the experience and would fully recommend you to others. Thank you.”
Marine Science IGCSEGeography IGCSE“I love Brainy Lemons so much I’ve been recommending it to others. What I found, as a parent, the most useful was the timetable feature. I could put when I wanted the course to finish into the timetable and loved how it worked out a weekly set of lessons. This gave us plenty of time for revision and exam practise and my child went into the exam feeling confident.”
Environmental Management IGCSE“My son is home educated and we signed him up to the Geography and Business courses. We got a discount when signing up for 2 courses and so it worked out really good value for money. My son has found it easy to use just following through the lessons and it really helped to be able to set a deadline to keep my son on track. I would really like to see more subjects and more options to pay where you can spread the cost as being home educated and having to pay for all education yourself can really add up.”

Good to know
Does it follow the AQA 8462 specification?
Yes. The course was planned from the AQA 8462 specification so every part is taught, in order. The quizzes, games and flash cards are all written from the lessons, so you only practise what's in the specification.
Are the games really learning, or just for fun?
Both. You can only win by answering questions on the lesson, and every wrong answer shows you the right one. Testing yourself like this is one of the best-proven ways to remember things, and the games mean students happily do a lot more of it.
Can I try it before I pay?
Yes. The first 3 lessons are free, including their quizzes, Lemonaire and Last Stand. No card needed.
Who is it for?
Students studying AQA GCSE Chemistry at school who want extra help, home-educated students, private candidates and adults going back to study.
What do I need to use it?
Just a web browser. It works on phones, tablets, laptops and computers, so you can study anywhere.
Does the price include the exam?
No. Exams are booked and paid for separately with an exam centre. The course gets you ready for them.
