Master Chemistry
Practice 24 skills with 150 questions — instant feedback, SmartScore tracking, and WASSCE elective & university prep aligned
About Chemistry on DigiTransact Mastermind
Chemistry is the gateway elective to medicine, pharmacy, nursing and chemical engineering. WASSCE Chemistry demands both conceptual understanding and calculation accuracy — the mole concept alone decides many grades.
Each of the 24 Chemistry skills carries its own SmartScore from 0 to 100, so progress is measured per topic rather than as one overall grade.
All 150 Chemistry questions come with the written reasoning behind the answer, so a wrong attempt still teaches the method.
Chemistry work is filed under Senior High, University, so you only see sets that match the stage you are studying.

Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
Learning outcomes
After working through the Chemistry practice sets you should be able to:
- Atoms and the periodic table: Atomic structure, isotopes and periodic trends for WASSCE Chemistry.
- Acids, bases and salts: pH, neutralisation and salt preparation for WASSCE.
- The mole concept: Moles, molar mass and simple stoichiometric calculations.
- Electrolysis and redox: Oxidation, reduction and electrolysis.
- Atomic structure: Understand sub-atomic particles, atomic number and mass number.
- Acids, bases & salts: Understand acids, bases, the pH scale and neutralisation.
Skills You'll Master
150 practice questions across 24 skills — aligned with WASSCE Elective Chemistry and university foundation standards, built for WASSCE elective candidates and university-prep students in medicine, pharmacy and engineering.
- Atomic structure & the periodic table
- Chemical bonding & molecular structure
- Stoichiometry & the mole concept
- Acids, bases & salts
- Redox reactions & electrochemistry
- Organic chemistry — hydrocarbons & functional groups
- Rates of reaction & chemical equilibrium
- Practical chemistry & qualitative analysis
Sample questions
Real questions taken from the Chemistry question bank, shown with the working learners see after answering.
The electron configuration of a neutral sodium atom (Z = 11) is
- 1s2 2s2 2p6 3s1
- 1s2 2s2 2p7
- 1s2 2s2 2p5 3s2
- 1s2 2s1 2p6 3s2
Working: Eleven electrons fill 1s, 2s and 2p, leaving one electron in 3s.
An acid has a pH that is:
- Greater than 7
- Equal to 7
- Less than 7
- Exactly 14
Working: Acids have pH values below 7; the lower the pH, the stronger the acidity.
The number of protons in an atom is its:
- Mass number
- Atomic number
- Neutron number
- Valency
Working: Atomic number = number of protons; mass number = protons + neutrons.
How It Works
Browse skills organised by category and level — from KG to University — and choose exactly what you want to practise.
Work through curriculum-aligned questions at your own pace. Every question is written to match how it is examined.
See immediately whether you were right, with a clear explanation after every answer so mistakes become learning moments.
Each skill is scored 0–100. Reach 100 to master the skill, earn badges, and climb the leaderboard.
Why Practice Chemistry
Each skill targets one concept, from balancing equations to titration calculations, so you can build mastery systematically instead of cramming the whole syllabus at once.
Instant explanations reinforce the “why” behind every reaction, preparing you for both objective and theory papers.

Frequently asked questions
Does this cover the WASSCE Elective Chemistry syllabus?
Yes. Skills span atomic structure, bonding, stoichiometry, acids and bases, redox, organic chemistry and equilibrium — the core of the WASSCE Elective Chemistry syllabus.
Can I practise mole concept and stoichiometry calculations?
Yes — dedicated skills drill mole calculations, concentration and stoichiometry with step-by-step worked solutions for every question.
Is this good preparation for medicine or pharmacy admission?
Strong Chemistry grades are mandatory for medicine, pharmacy and allied health programmes in Ghana. These skills build the WASSCE performance and university-level foundation those courses require.
