14 sure is an impressive age to start with CAD, when I was 14 I never thought about anything like that xD. I am sure you will get really good at it if you keep practising . I use SolidWorks because of my engineering study but 3dsmax looks great for for games and creating figures. Our schoolsystem is a bit different but with 17 you are def. the youngest one in the class when you start your study, I guess I was a bit early. I will already be graduating for my 4year bachelor next year x.x
I'm using 3ds max. I started with Maya but once I went to Ubisoft Academia (a game dev camp) I started using 3Ds max. And yeah, 3Ds max is great for games. I actually already worked on a game which is on steam right now. It's named Aperture Tag.
And I think I'll graduate from the university at 23-24...
You already did many things for your age! You sure will get good at it later. I wish I did all those things haha. I guess you want to be a game developer later or not? We don't have as many summercourse options as Canada or America (actually nearly nothing here).
23-24 years is not that old either, graduating at a younger age is also not always the best thing since you are still so young and you want to enjoy life too . I might do a second bachelor (can do a second one related to my study in 1 year) or a master here or in an another country if I do not get a good and fun job after this. Luckily my small country do has some big companies where I could work for later.
