International experience is “extremely valuable” to Fernanda Juárez Trevino, a Mexican student on the Bachelor of Business Administration at Esade business school in Barcelona. “One of the reasons I chose to study at Esade was the opportunity to share classes and meet people from all over the world and broaden my thinking,” she says.

At its height, Covid-19 put paid to most foreign exchange programmes, through which students can spend a semester at a business school in another country. And, while some of these are resuming, cross-border travel remains challenging and uncertain as the pandemic continues.

But Trevino, who wants to pursue a career in investment banking, is building her international experience another way: by enrolling on two online courses in finance and quantitative analysis — one at SDA Bocconi School of Management in Milan, Italy, and the other at the University of St Gallen in Switzerland.
