Im in a school which is only partly 3d focused. All you get from a school like that is the basics of everything, which wont propably get you far if you only try to go into the indurstry with only what a school like that taught you. If you plan to git gud in modeling / rendering / animating, thats going to take some time.
If you plan to take the courses, I suggest to do so if you plan on improving by yourself afterwards. It can be helpful to have someone guide you trough the basics, for example if you encounter some problem, the tutorial youre watching online propably doesnt have that problem, and it slows your learning down alot and demotivates you easily as you have to search for the said problem fix. While if you are in school and someone who knows things is around, he propably gets that error solved in no time.
>Most people tend to rig / animate in Maya, as it tends to do a better job at that than Max. Max is still valid for it, though.
Also, my school is generally bad, so a decent one might teach more than just the basics, or in better quality in overall.
