How many moles are in 36 g of water (H₂O, M = 18 g/mol)?
You wrote 0.5 mol. You divided molar mass by mass — flip it. Moles = mass ÷ molar mass = 36 ÷ 18 = 2 mol. Keep your units lined up and this one won't catch you again.
Pick a topic. Answer ten. Get the why.
A single, calm loop you can finish in one sitting on your phone — no chat, no streaks, no noise. Just the paper, marked, with the reasoning behind every answer.
Pick a topic
Choose from the WASSCE chemistry syllabus — the mole concept, acids & bases, organic chemistry, electrolysis. High-yield topics are flagged.
Answer ten questions
Ten exam-style questions, one per screen, labelled A–D like the real paper. Select, check, move on — a session takes under ten minutes.
Get the why
Every wrong answer comes back with the exact reasoning slip named in plain language, the correct step, and one rule to remember for the exam.
One grader, purpose-built for WASSCE chemistry
Chegg, Khan Academy and Tutor.com are general tools. This is tuned to one syllabus and one teacher's marking voice — so the feedback actually sounds like a lesson.
Plain-word mistake notes
Not just “incorrect.” Each wrong answer names exactly where the reasoning slipped — balancing, units, formulae — in words a 16-year-old reads easily.
Marks the whole class at once
A week of practice papers graded without a single red pen — so every student gets real feedback, not just the first few you had time for.
Misconception tracking
See which mistakes keep recurring across the class, so the next lesson targets the thing most students are actually getting wrong.
What it isn't — on purpose
Doing one thing properly beats doing ten things loudly. So we left a lot out, on purpose:
Chemistry only. WASSCE only. Web only. It runs in any browser on any phone — no download, no heavy app, no data you can't spare. The whole product is the practice loop and the honest, plain-language feedback behind it.
Kept small, by design
Built first for one teacher's own students, and priced so cost is never the reason a student can't practise.
