The jump is real — but it's specific

A-Level Chemistry is not “harder everything”. It's faster — a topic your GCSE course spent three weeks on gets three lessons. Some content may even be set as independent study. It assumes calculation fluency: moles, concentrations and unit conversions are the working language of the course, not a topic within it. It expects you to write chemical formulae from memory, quickly, without being asked. And it comes with an unwritten contract of regular hours of independent study a week, starting immediately.

What your school expects

Most schools will set transition work over the summer — and most test it, formally or informally, in the first two or three weeks of term. This will likley include maths skills (standard form, significant figures, rearranging), moles and the mole equation, formula writing and balancing, concentration, percentage yield and error, and possibly practical vocabulary.

I built Bridge the Gap — a free, interactive version of the same material. It covers the same skills, but it marks itself, explains every wrong answer the way an examiner would, and works on your phone.

The seven skills

1 · The maths toolkit. Standard form, significant figures, unit prefixes, rearranging equations without formula triangles, and calculator order of operations. None of it is hard; all of it has to be automatic. Module 1 drills exactly this.

2 · Writing formulae. Knowing the common ions and the formulae methods turns a minute of head-scratching into five seconds of routine. Module 2 builds the fluency, from simple ionic to balancing and ionic equations.

3 · Moles. The currency of the entire course. If n = m ÷ M isn't second nature, every topic that follows wobbles. Module 3 takes you from Mr warm-ups to particle conversions — and then asks you to escape the Mole Maze.

4 · Concentration. Titrations arrive within weeks of starting Year 12, and every titration calculation stands on c = n ÷ V with the volume in dm3. Module 4 makes the conversion part of the habit.

5 · Yield, error and uncertainty. Real chemistry never gives you 100%, and A-Level expects you to say how far off you were and why — including the detail that two readings double the uncertainty. Module 5 covers the two percentages.

6 · Practical language. Accurate, precise, repeatable, reproducible, random and systematic error — A-Level practical work is assessed on vocabulary as much as technique. This joins the course as Module 6 in September.

7 · A taste of what's new. The first genuinely new content of Year 12 — shells splitting into sub-shells, electron configurations, ionisation energy — rewards a preview. Module 7 lands in September too.

If you want a head start with support

I keep my A-Level student numbers deliberately small so I can teach properly, and September places go first, usually before results day. If the calculation modules felt harder than they should, that's the signal worth acting on. Get in touch for a free, no-obligation chat to see if we're a good fit.

Bridging FAQs

Do I need to do my school's bridging work as well? Yes — schools often test it in September. This course covers the same skills interactively, so use it to make the booklet faster and to check your answers make sense.

Is A-Level Chemistry hard? It's a step up in pace and depth, but the students who struggle are almost always missing specific GCSE skills — calculation fluency above all. Fix those before September and the first term is very manageable.

I did Combined Science — am I behind? No, but you met moles more briefly than Triple students. Modules 1–4 cover the gap; give them extra time.

How long does this take? The diagnostic takes 10 minutes; each module 15–25. Little and often beats one long session — 20 minutes a day for a fortnight is plenty.

Is it really free? Yes — no sign-up, nothing stored beyond your own browser. I make my living from one-to-one tuition; these resources are how students find out whether my teaching suits them.
