You need to be free to commit to full time study for 12-24 weeks. You need to be prepared to work hard and push yourself.
You should go into this training with a view to entering full time work after you’ve finished the course. (Which, let’s be honest, is pretty amazing). There aren’t many courses out there that ask you to be ready for a job after you’ve completed the work.
Finally: be excited. Enthusiasm will be your best friend. If you’re excited about building digital skills that will make you job ready, then this could be a life-changing opportunity.
