A paramedic from London Ambulance Service visited Nescot on Tuesday to speak to the students about career opportunities.
Mark Vials, based at Deptford ambulance station, came in on his day off to chat to Level 2 and first-year Level 3 Uniformed Public Services students about his experiences and to answer questions.
Mark, a trained carpenter who used to build sets for productions in the West End, told the group about the different training routes available, where to search for vacancies and what personal qualities they would need.
"The best advice I could give anyone joining any profession is to research as much as possible so you have a really good idea of what the job will be like," he said.
"I absolutely love being a paramedic, but it can be physically, mentally and emotionally tough, and you have to be prepared for that.
"You need to be able to stay calm during difficult situations, to think on your feet, to communicate well and to work well as part of a team."
Head of Department Neil Barnett said: "We’re really grateful to Mark for coming to speak to the students today, and we hope they found it useful as they think about their next steps."
