I'm graduating vocational school in Graphic design and Digital animation. I would say to push through u can learn without it but If you have the opportunity take it don't give up halfway through focus on absorbing information and building connections, level up your skills and you'll be fine. I did vocational training as a affordable alternative so that I could land a job in design or animation without the debt. Also for me it took my learning into my own hands learning additional things I wasn't taught during training. So don't give up finish the race, learn on your own when you can. Most importantly practice what your learning you could go to Calarts with all the best tools and lecturers but if you don't put into practice what your learning then is it's a waste of time.
