PSTAR vs the PPL written exam: what changes, and the 90% vs 60% trap

The results letter says 47 out of 50. Somewhere in a filing cabinet at the school, a student pilot permit now carries our name, and the next time an instructor climbs out on the taxiway it will be legal. We just cleared the PSTAR — 90%, pre-solo, every question drawn from a bank we were allowed to study cold.^[1] Then someone in the hallway says the thing that starts the trouble: the PPL written? don't sweat it — that one's only sixty percent.

They are right about the number and wrong about what it means.

Two exams, and they are not the same game

A Canadian pilot meets two written exams early, and it is easy to file them under one heading — the writtens — as if they differ only in size. They differ in almost everything that matters: when you sit them, what they cover, whether you can see the questions in advance, and how hard you have to score.

The PSTAR comes first. It is the pre-solo air-law exam, and it guards the student pilot permit — the document that makes a solo legal at all.^[2] Fifty questions, selected from a study guide that publishes every question it can ask: the guide says it is divided into 14 sections and holds "some 200" questions, and the current seventh edition carries exactly 185.^[1] The pass mark is 90% — 45 of 50, so you can miss five — and the paper is corrected to 100% afterward, every miss reviewed until the gap closes.^[1] The subject matter is narrow and legal: the CARs, ATC clearances and instructions, VFR procedures at controlled and uncontrolled aerodromes, Special VFR, circulars and NOTAMs.^[1]

The PPL written — Transport Canada codes it PPAER, the Private Pilot−Aeroplane examination^[3] — comes later, on the road to the licence itself.^[2] It is 100 questions over three hours, split into four mandatory subjects: Air Law, Navigation, Meteorology, and Aeronautics − General Knowledge.^[3] The pass mark is 60% overall. And there is no published bank — nothing to study cold, no list of 185. You study the subjects; the exam picks the questions.^[3]

The 90-versus-60 trap

Line the two numbers up and the intuition writes itself: the bigger prize must be the harder exam, so the PPL written — the one that leads to an actual licence — must be graded harder than the little pre-solo paper. The marks say the opposite. PSTAR demands 90%; the PPL written asks 60%.^[1][3] If a high pass mark meant a hard exam, PSTAR would be the fearsome one.

It isn't, and the reason is the whole point. A pass mark is calibrated to the exam underneath it. PSTAR can demand 90% precisely because it is short, narrow, and published in advance: when every question is on the table and the subject is a single body of law, near-perfect is a fair bar — and the height of it is deliberate, because these are the pre-solo safety rules and Transport Canada wants them close to reflexive before the door shuts. The PPL written asks only 60% because the thing you are scored against is four subjects deep, arithmetic included, with questions you have never seen. Sixty percent of that is not sixty percent of a vocabulary quiz.

So the honest reframe: 90% on an exam you can study cold and 60% on an exam you cannot are two different kinds of hard. The lower number is attached to the harder paper.

The gate most students miss: 60% in every subject

Here is the part the hallway advice leaves out. The PPL written's 60% is not only an overall score — the exam is sectionalized, and you must reach 60% in each of the four mandatory subjects as well as 60% overall.^[3] The two conditions are separate, and the per-subject one is where candidates who "averaged fine" come undone.

Picture a student who is strong on air law and navigation and shaky on weather. They can post a comfortable overall score and still fail, because Meteorology came in under 60%.^[3] You cannot average your way past a weak subject; a peak in one bucket does not refill another.

There is a mercy built in, and it is worth knowing. If you clear 60% overall but miss a single subject, Transport Canada assesses a partial pass: rather than rewrite the whole thing, you sit a supplementary examination covering only the subject you failed.^[3] Miss the overall 60%, though, and you rewrite the complete exam.^[4]

PSTAR has no equivalent trap, because it has no subjects to fail independently — it is one body of material, the CARs and ATC procedures, scored as a single number.^[1] One bucket, one bar.

Open bank versus closed: two kinds of studying

The deepest difference is not the marks — it is what you are allowed to see.

PSTAR's bank is public, and that changes the job. The guide even asks you to research the reference behind each question rather than memorize answers,^[1] but the questions themselves are in front of you, so the long tail of odd one-off facts is learnable: you have the list. Prep for PSTAR is, in the end, prep against a known set.

The PPL written hands you no list. You study Air Law, Navigation, Meteorology and Aeronautics − General Knowledge as bodies of knowledge, and the exam draws its own questions from them.^[3] That flips the task from recall to comprehension. Navigation is the clearest tell: you carry a flight computer, a ruler and a protractor into the room and actually work problems — wind triangles, ground speed, fuel — because the exam expects computed answers, not memorized ones.^[3] You cannot pre-read a wind triangle you have never been given the numbers for.

This is why the two exams reward different weeks of studying. PSTAR rewards drilling a finite bank to the 90% bar. The PPL written rewards understanding four subjects well enough to answer questions nobody has shown you.

Even the rules for failing are different

The two exams part ways one more time, at the worst moment — a fail — and the contrast tells you how Transport Canada thinks about each.

Fail the PSTAR and there is no waiting period: you may rewrite as soon as you have been notified and have reviewed your weak areas.^[4] The system wants the pre-solo student back in the seat quickly. The PPL written is stricter — a first failure carries a 14-day wait before a rewrite, a second failure 30 days, climbing from there.^[4] These are graded exams for a graded licence, and the cool-down is part of the design.

None of that is a reason for nerves. It is a reason to sequence the work deliberately.

What to study first

If you have just cleared PSTAR, you are holding an advantage most students let go to waste: the air law is still warm.

Sit PSTAR first, and get it done. It is the gate to your first solo and the faster of the two to clear, because the bank is open — the mark is high, but the target does not move.^[1] There is no reason to let it drift behind the flying.

Then treat the PPL written as a longer campaign across four subjects, and start where you are already strong. The Air Law subject on the PPAER is built on the same CARs and ATC procedures the PSTAR just drilled — the regulations do not change between the two papers, so that knowledge transfers almost intact.^[3][5] Bank the transfer: refresh air law, confirm your footing there, then spend the real hours on the three subjects PSTAR never touched — Navigation, Meteorology, and Aeronautics − General Knowledge — because those, and the per-subject 60% gate, are where the PPL written is actually won or lost.^[3]

The hallway shorthand — the PPL's only sixty percent — is true and misleading in the same breath. Sixty percent of a closed, four-subject, calculate-it-yourself exam, with a floor under every subject, is a harder afternoon than 90% of an open, single-subject bank you were handed in advance. They are two different games wearing two different numbers. Passing the PSTAR proves you can drill a known set to a high bar. The PPL written asks something else — that you understand four subjects well enough to meet a question you have never seen. Study each for what it actually is, and the lower number stops looking like the easy one.
