I didn't have ANY previous experience with coding before, and decided to join 11-week Full-stack. The intensity of the program was excitingly challenging!
I think what makes CodeOp such a unique school for me was the team of teachers & staff. They are very high-skilled and properly hand-picked for each role. They definately help you in whatever you need, encouraging you to improve.
The program is very well put together and complete. We also had private come-in speakers that could answer all our questions and useful workshops!
Non-Academic related, it doesn't give that much help to non EU-citizens or non Spanish residents like student visa or help you with housing if you're not living in Barcelona. So you'll have to figure out another way.
But besides that, I would totally choose this school again!
