I've sat at the back of P6 classrooms in Kigali, Musanze and Rubavu for two years. Here is what actually moves the needle on the leaver exam — not generic advice, the real thing.
I want to start with a number. In 2024 the Rwanda national P6 leaver exam was sat by roughly 275,000 children. About 97% of them passed. That sounds great until you read the next line: only around 40% got the marks they needed to be placed in their first-choice secondary school. The rest got a school — but not the one their parents had hoped for, not the boarding school down the road, not the school with the math teacher who's known across the district.
That gap between “passed” and “placed where you wanted” is what this guide is about.
I'm Eric. I run Ganzaa. For two years now I've been spending one or two days a week sitting at the back of classrooms — primary schools in Kicukiro, in Musanze, in Rubavu, in Huye. I watch kids do practice papers. I watch teachers mark them. I sit with parents on Saturday mornings and read the WhatsApp messages they send each other at 10pm the night before exams. None of what I'm about to write is theoretical. It comes from those rooms.
The P6 national exam (the “ikizamini cy'ireme cyo kurangiza amashuri abanza”) is set by NESA and aligned to the REB competence-based curriculum. Five subjects, 100 marks each:
The aggregate decides your placement. But here is something you don't hear in the official documents: the curriculum is competence-based, which means examiners aren't looking for facts so much as application. They give you a situation — a small farmer in Bugesera deciding how much fertilizer to use, a student designing a class survey, a household budgeting in RWF — and you have to do something with what you know. Memorising answers from past papers won't protect you when the question is structured differently.
The most common P6 prep strategy I see goes like this: “Let me re-read the textbook from the start.” Three weeks before the exam, every kid I've sat with is doing this. They open the math textbook to chapter 1 and start working forward.
It doesn't work. Re-reading is the lowest-yield study activity that exists. The research on this is unambiguous: students who re-read score the same as students who didn't study at all. The students who improve are the ones who practice retrieval — they shut the textbook and try to do problems from memory, then check what they got wrong.
So the first rule, and the rule almost no one follows, is: spend more time being tested than being taught. Past papers, not textbooks. If you have three months until the exam, you should be doing a full past paper every week per subject from week one. That's 60 papers in three months. Mark them honestly. Track which questions you keep getting wrong. That list — the questions you're consistently failing — is the only study list that matters.
Here is the rhythm I've seen work for the kids who go from “passing” to “placed in their first choice.”
One full past paper per subject, per week, under timed conditions. Don't mark them yourself — get a teacher or parent to mark them, or use Ganzaa's past papers library which auto-marks. The goal of these four weeks is not to improve. It's to find your weak spots.
By the end of week 4 you should have a one-page list per subject titled “questions I keep getting wrong”. For most kids it looks something like:
Now you spend 60–70% of your study time on those weak-spot lists. Not on the easy stuff. Not on the subjects you already love. The hardest, most uncomfortable questions. This is where almost everyone quits — it doesn't feel productive, you're wrong a lot, your confidence drops. That's the sign it's working.
Three drilling rules I've learned from the kids who actually improve:
Two full mock exams per week — alternate subjects. Use real past paper conditions: timer, table, no phone, no music with words. Mark strictly. By week 11 your scores should be 10–20% higher than where they were in week 4. If they're not, it's almost always one of two things: you're not actually doing past papers (you're re-reading), or you're not being honest when you mark.
The week before is for sleep, light review of your mistake log, and packing your bag. Stop drilling new content. The brain consolidates what you've learned during sleep — pulling all-nighters the week before is one of the worst things a P6 student can do. I've watched smart kids tank because they were running on four hours of sleep.
Two patterns. First: kids skip the geometry questions because they look hard, then run out of time on the easier number questions later. Bad strategy — the geometry questions are usually structured so the first sub-question is worth easy marks. Always attempt them.
Second: fractions and percentages are the most common topic in the paper, and the most commonly failed. If a P6 student spends one focused week just on fractions and percentages, their math score moves more than from any other single intervention I've seen.
Diagrams. The exam loves diagrams. Drawing a labelled diagram of the digestive system, an electric circuit, a flower's parts — these come up every year and they're worth real marks. Most kids underprepare on diagrams because they don't feel like “real” studying. They are. Practice drawing the same five diagrams until you can do them in 90 seconds.
Dates and place names trip up more kids than the conceptual questions do. The conceptual questions (“Why did X happen?”) are easier to bluff with general knowledge. The factual questions (“What year did Y happen?”) are not. Memorise the timeline of Rwandan history from 1885 to 1994, then 1994 to today, in five-year buckets. That alone is worth ten marks.
The composition is where most kids leave easy marks on the table. Two rules: plan it for two minutes before writing, and finish it. An incomplete composition with a beautiful first paragraph scores worse than a complete composition with average sentences throughout.
Don't skip ubuvanganzo just because you grew up speaking the language. The literature questions reward kids who've actually read the prescribed texts, not kids who can speak fluently at home. Read at least three of the prescribed novels and write a one-paragraph summary of each.
I've had a lot of parents ask me this. Here is what I tell them:
Your school should have past papers — most do, going back at least three or four years. If they don't, the easiest source is Ganzaa's past papers library: every paper from recent years, free, with an interactive practice mode that marks you as you go.
If you want to start one thing today, start there. Pick a math paper. Sit down with a timer. Don't look at the answers until the timer runs out. Mark it honestly. That's the start.
The P6 exam feels enormous when you're 12. It is enormous — it's the first big institutional test of your life. But it's also a test that 97% of kids pass. With a structured plan, honest practice, and decent rest, you will be one of them. The kids I've seen go from average to top-10% in their school all did the same boring thing for three months: past papers, mistake log, sleep. That's it.
Good luck. Mwitwararike, mwige neza.
I've tested the major learning apps available to Rwandan students. Here is the honest, opinionated review — what works, what doesn't, and what to skip entirely. With my biases declared up front.
S3 is the second turning point in a Rwandan student's life. Past papers are the highest-leverage tool you have — and most kids use them completely wrong. Here is how to do it right.
Ganzaa is Rwanda's online learning platform — free for individual students, with REB-aligned practice and past papers. Schools get the first term free.
