Do Students Really Need Exams to Learn?

The other day in chemistry class, someone said the lesson felt chill. A classmate said, "Yeah, that's how I like it," and added, "If only we didn't have exams too." The teacher laughed and said, "Yeah, so you could do nothing all day."

I've heard that idea my whole life in Greece: take the exams away and students stop learning. It never sounded right to me, so I looked at the numbers.

Two very different systems

In Sweden, students don't get grades until year 6, and there is no national university entrance exam. Getting into university mostly depends on your school grades, with an optional admissions test. Sweden does run national tests in years 3, 6 and 9, so it isn't a country without exams. It just doesn't hang the whole system on one.

In Greece, for most students, high school is built around the Panhellenics: a few exams in June that decide your future. I'm not doing them myself, I sit IAL exams, but I can see how deep that logic runs.

What the numbers say

- Reading (PISA 2025): Sweden 466, Greece 423, OECD average 461. PISA treats about 20 points as roughly a year of school, so that gap is close to two years.

- Maths: nearly one in two Greek 15-year-olds is below the basic level, and Greece is under the OECD average in maths, reading and science.

- Creativity (PISA 2022, the first time it was tested): Greece scored 27 out of 60, the OECD average was 33. Finland, another Nordic country, scored 36.

- Innovation (Global Innovation Index 2025): Sweden is 2nd out of 139 countries. Greece is 42nd.

- Sustainable development (SDG Index 2025): Sweden is 2nd in the world. Greece is 28th in Europe.

What this doesn't prove

School is not the only reason for any of this. Economy, institutions and funding matter a lot, and I'm not claiming that removing exams creates a better country.

Sweden also has its own problems. Between 2022 and 2025 its scores fell by 21 points in reading and 18 in maths, and it is now only around the OECD average. So Sweden is not a model to copy.

The point is narrower. If exams alone were what made students learn, the most exam-driven systems should be at the top. They aren't.

Discipline is not fear

School has taught me discipline: getting through things you don't enjoy and finishing them anyway. That matters, and exams are part of it. But discipline and fear of failing are two different things.

A student who opens the book only because a test is coming learns how to pass tests. A student who wants to understand is the one who later builds something, invents something, fixes something.

Where this leaves us

This isn't about one teacher. It's a way of thinking a lot of us in Greece grew up with: without pressure, nobody works. As long as we believe that, school will stay about the fear of failing and not about learning, and that's why we won't really move forward.

So here's my question. If there were no exams tomorrow, would you still study?
