Chemistry is where memorisation meets problem-solving: you need the concepts and the reps. The Study Mill turns your own chemistry lectures and problem sets into worked explanations, flashcards and quizzes — so reaction mechanisms and equilibria make sense instead of being memorised blind.
Chemistry papers are mostly worked problems, and marks are distributed across the working rather than the final number. That changes how you should revise.
Stoichiometry, equilibrium and thermodynamics problems where method marks dominate. A unit-conversion slip costs one mark; skipping the setup costs most of them.
Curly arrows showing electron movement, step by step. Examiners mark the arrows, so a right product with wrong arrows scores poorly.
A substrate and reagents you have not seen combined before. Only understanding the mechanism generalises here — memorised reaction lists do not.
The Study Mill generates questions in these formats from your own material — so practice looks like the exam, not like a glossary.
Two examples of what comes back after you upload a set of chemistry slides. Generated from your material, phrased the way your course tests it.
Why do SN1 reactions favour tertiary substrates while SN2 reactions favour primary ones?
SN1 goes through a carbocation intermediate in the rate-determining step, and three electron-donating alkyl groups stabilise that positive charge. SN2 is a single concerted backside attack, so the same three alkyl groups become steric blockers — bulk that shields the electrophilic carbon.
Calculate the pH of a 0.10 M solution of acetic acid (Ka = 1.8 × 10⁻⁵).
pH ≈ 2.87. For a weak acid, [H⁺] ≈ √(Ka × C) = √(1.8 × 10⁻⁵ × 0.10) = √(1.8 × 10⁻⁶) = 1.34 × 10⁻³ M, so pH = −log(1.34 × 10⁻³) = 2.87.

Chemistry rewards understanding mechanisms, not memorising them — and problem sets pile up fast when you have no one to ask why.
In organic chemistry, follow where electrons move and mechanisms stop being memorisation.
Chemistry is a doing subject — one worked problem beats re-reading the chapter twice.
Half of exam mistakes are unit and mole conversions. Drill them until they are automatic.
"Orgo mechanisms finally made sense once Milli walked me through my own lecture examples. Passed with a Distinction."
Yes — worked explanations are the point for chemistry. Ask Milli to walk through a problem and you get the setup, each step and the reasoning for it, and you can ask "why that step?" at any point without waiting for a tutorial.
It handles the reasoning behind them well — which nucleophile attacks where, why a particular intermediate is favoured, what changes when you swap the solvent. Drawing curly arrows is still something you should practise on paper, because that is how the exam tests it, but the concepts that make the arrows obvious are exactly what it explains.
Yes. Uploading a problem sheet gives you variations on the same question types rather than the identical questions back, which is the useful thing — most students already have the answers to the sheet and need more reps at the same difficulty.
Only through volume, which is the honest answer. Conversion slips are a fluency problem, not a comprehension one — generating a daily handful of short calculation questions and doing them until they are automatic is what fixes it.
