When Frank graduated from the International School of Lausanne (ISL), he knew two things: he cared deeply about the environment, and he wanted to challenge himself. What he didn’t know yet was exactly how those interests would shape his future.
A gap year that included Swiss military service helped him discover the answer.
Today, Frank studies Business and Environmental Science at the University of Exeter, a degree that combines sustainability science with economics and business. His journey from the Swiss army to environmental economics offers valuable insights for students thinking about life after school.
The day introduced recruits to the many roles available within the Swiss army.
“There are so many options — combat roles, transportation, aviation, communications. There are probably more than a hundred different paths you can take.”
After the orientation, Frank attended two further days of testing in Payerne, where recruits undergo medical examinations, psychological assessments, and fitness evaluations. These tests help determine which role may suit each individual.
At the time, Frank was determined to take on a physically demanding role and was eventually placed in infantry training.
Basic training lasted four months and, according to Frank, was far more demanding than he initially expected.
“Physically I was okay compared to some people, but mentally it was a real shock to the system.”
The first eight weeks focus heavily on preparing recruits for high-pressure situations. Sleep is limited, food is basic, and discipline is strict.
At the start, new recruits even lack a badge on their uniform.
“Without a badge you’re basically a nobody,” Frank explains. “Once you earn it, you gain a bit more respect.”
As training progressed, the experience became more rewarding. Frank’s infantry unit worked in small combat teams of seven, building strong bonds through training exercises and scenarios.
“Those people became some of my closest friends. We still hang out today.”
Looking back, Frank encourages younger students to explore the full range of military opportunities before choosing a path.
“I was very focused on doing something physically demanding, but there are many other roles where you can learn valuable skills.”
Some roles allow recruits to gain professional qualifications, such as truck driving licences or specialised technical training, so it is worth doing your research well, consider your strengths and the opportunities available before signing up.
He also points out that Switzerland offers civil service as an alternative.
“You can work in environmental projects, like helping manage forests in the mountains or learning practical conservation skills.”
For students considering a physically demanding role, Frank offers one clear piece of advice:
“Train beforehand — it will make the experience much easier.”
Frank’s interest in environmental issues began during his time at ISL. In the IB Diploma Programme, he studied Higher Level Biology and Geography, two subjects that shaped his academic direction.
“Biology gave me the science, and geography explored sustainability and human development.”
When researching universities, Frank looked carefully for programmes that combined these interests. Eventually he found the Business and Environmental Science degree at the University of Exeter, which integrates environmental science with economics and policy.
The course spans multiple disciplines.
“I’m in two departments — the business school and the science faculty — and everything connects surprisingly well.”
Frank quickly noticed that the IB had prepared him well for university life.
“The essay writing, research skills, and balancing multiple subjects really helped.”
Many of his classmates had studied A levels, and Frank felt the IB’s breadth gave him an advantage, particularly in research and independent study.
The Extended Essay proved especially valuable.
“That was my first big research project,as I approach my thesis, I am referring back to it. The structure and guidance provided at ISL is standing me in good stead for my undergraduate.”
Managing multiple subjects simultaneously also mirrored the demands of university study.
“In the IB you’re juggling six subjects at once. At university I have seven or eight modules each year, so that skill really helped.”
Frank believes that taking a gap year before university was one of the best decisions he made.
Military service, work experience, and travel gave him the chance to develop independence and reflect on his future.
“It helped me grow up and figure out what I actually wanted to study.”
In fact, the gap year led him to change his university course shortly before starting.
Originally he planned to study biodiversity conservation. After reflecting on his interests, he switched to a broader programme that included both science and business.
“That decision definitely worked out for the better as my degree combines my interests.”
If Frank could speak to his Year 13 self, his message would be simple: “don’t panic!".
“The IB score is important to get where you want to go, but once you’re there it’s really the skills that matter.”
He encourages students to focus on curiosity and genuine interest rather than simply chasing grades.
“Choose something you care about. When you enjoy your subject, you naturally want to learn more.”
Frank credits ISL’s international environment with helping him adapt smoothly to university life abroad.
“ISL is so multicultural. It really prepares you for living and studying in a different country.”
Combined with the academic rigour of the IB and strong teacher support, the school gave him skills that continue to benefit him today.
“A lot of what I learned at ISL transfers directly to university — especially research, essay writing, and organisation.”
Frank is currently completing his thesis on the environmental impacts of the outdoor industry in the Alps, exploring how tourism, skiing, and outdoor recreation affect biodiversity and fragile ecosystems.
His work reflects a growing field that combines environmental science with economics and policy.
For Frank, the journey from ISL to military service and university has been full of unexpected lessons.
And his advice for current students?
“Don’t stress too much about the IB. It’s tough at the time, but it prepares you incredibly well for everything that comes next.”
