Where do I start preparing for my O/L or A/L exam?
Start with one subject, not with a plan for all of them: open that subject's page below, then take the free quiz to find out which parts of it you cannot yet do. This page is the index — every page we publish for an exam student, what each one is for, and which of them you can use right now without an account. The examination itself, its timetable and its results come from the Department of Examinations, not from us ([S1], [S2]).

Start here — free, and no account
- Free Quiz — answers a few questions from your syllabus and shows you which topics you are weak in.
- A/L stream selector — works out which A/L streams your subjects fit, and what each one leads to.
- Z-score tool — predicts a Z-score from marks you enter, so you can see where you would stand.
- Grade 9 subject wizard — walks you through the three O/L elective groups.
None of those asks for an account, a card or a phone number.
Your subject
These are the subject pages we publish today. Each sets out what the syllabus covers and what the paper asks for.
Ordinary Level
Advanced Level
If your subject is not on that list, we have not published a page for it yet. Browse subjects shows the full list as it grows.
How to sit the paper, subject by subject
Each guide takes one paper apart: what the examiner is marking, and how to practise for it.
- O/L English — Master Paper I and Paper II with the 3-Phase Protocol
- O/L Mathematics — The 4-Step Method-Mark Allocation Protocol
- O/L Science — The 3-Tier Diagnostic Method for Distinction 'A'
- O/L Physics topics — how to use AI to master them
The decisions around the exam
The examination is not the only thing being decided in these years. Each of these pages answers one question, with its sources.
- Which three electives should I choose for the O/L? → Which subjects should I choose for O/L?
- Which A/L stream, and what does each one require? → A/L stream selection
- How does the Z-score decide who gets a university place? → University entrance
- What are my options after the A/L, besides a state university? → Higher studies and jobs
What an account adds
An account is where the work is kept: your quiz results over time, the topics the system has seen you get wrong, a study plan built from them, and the AI coach you can ask about a question you are stuck on. What each plan includes, and what it costs, is on one page — Pricing.
