Is it a good idea to consider attending Barcelona GSE if you don't know any Spanish or Catalan?

Answer 1

It is a large thing to consider if you do not know any basic Spanish. It will be difficult to navigate and live safely. Most languages are best taught through immersion, however. So don't rule it out right away. Possibly consider some basic Spanish classes to brush up on day to day vocabulary for safety purposes. English and Spanish have a lot of similarities and may come easier than you think.
