Topics we’ll cover in the bootcamp
-
This topic is almost always the “opener” question in OCR A-Level exams.
Highly important takeaways we’ll cover:
Subatomic particles
Successive ionisation energies
Electron shells and shielding
Periodicity across periods
-
This topic is foundational across the A-Level syllabus, and you’ll need to be savvy in using mole calculations across various topics.
Highly important takeaways we’ll cover:
Mole calculations
Empirical and molecular formulae
Ideal gas equation
Titration calculations
-
Enthalpy Changes - one of those that trips students up, but when mastered, translates to sure marks.
Highly important takeaways we’ll cover:
ΔH definitions (formation, combustion…)
Bond enthalpies
Hess cycles
Calorimetry (q = mcΔT)
-
How Fast? is another topic that always gets a seat in the exams.
Highly important takeaways we’ll cover:
Rate equations
Orders of reactants and overall order
Rate constant (k) and unit derivation
Factors affecting rate of reaction
-
Very commonly examined, you’ll become comfortable with which way the equilibrium lies with changes.
Highly important take-aways we’'ll cover:
Kc and Kp calculations
Le Chatelier’s Principle
Factors that affect equilibrium position
-
Organic Mechanisms may not be a topic in and of itself, but it is the bedrock of several organic topics.
In part one, we’ll cover:
Reactions of alkanes, alkenes and haloalkanes
Curly arrow mechanisms
Reaction conditions and reagents
-
Organic Mechanisms may not be a topic in and of itself, but it is the bedrock of several organic topics.
In part two, we’ll cover:
Reactions of benzene, carbonyls and alcohols
Curly arrow mechanisms
Reaction conditions and reagents
-
Usually one of the final topics to be examined in A-Level Chemistry exams and one of the most mark-fetching.
Highly important takeaways:
Empirical formulae
Common IR peaks
How to interpret MS
NMR chemical shifts and splitting
-
Acids, Bases & Buffers
Acids and bases show up every single year — and once you understand how equilibrium ties everything together, this topic becomes one of the most reliable places to secure marks.
What it’s about:
How acids and bases behave, how to calculate pH, and how buffer systems resist changes in pH.You need to know:
Definitions of acids, bases and conjugate pairs
Strong vs weak acids
pH calculations
Ka, pKa and using the acid dissociation expression
Buffer solutions and how they maintain pH
Buffer and titration calculations
-
Transition metals can look intimidating at first, but once you get the hang of the colour changes and complex ions, this topic becomes one of the easiest places to pick up marks.
What it’s about: Properties and reactions of d-block elements.
We’ll be looking at:
Various oxidation states of metal complexes
Ligand substitution reactions
Colour changes and precipitation
-
General exam past paper practice on AS Paper 1 questions.

Hi, I’m Ope
I’m an online Chemistry tutor with over 15 years of experience and a two-time Russell Group graduate and scholar.
Not only am I hugely passionate about my subject, I know just how to chip away at complex topics so that are simpler to understand.
My approach is rooted in exam insight — I teach students how examiners think and help them to revise strategically in their personal time.
A series of topic-based exam paper practice masterclasses for A-Level OCR Chemistry
For 11 weeks leading up to the exam, I am hosting a series of masterclasses based on the most challenging topics in the OCR A A-Level Chemistry specification.
In each session, there will be a short teaching session with some recall. I’ll break down the key things that every A-Each masterclass includes a short, focused teaching segment and quick recall to secure the essentials. I’ll break down the key ideas every A‑Level Chemistry student must know for that week’s topic, then guide them through high‑level exam questions — showing them exactly how to craft A–A* answers and what examiners are really looking for. Students get time to attempt each question first, so they can actively apply the techniques before we work through them together.
By the end of the ten 60‑minute sessions, your child will have a clear, confident approach to the toughest OCR A topics that appear year after year. They’ll walk into the exam hall with stronger technique, sharper recall, and a noticeable boost in performance.
