I wanted to see if anyone has taken the Dartdrones 3D Mapping and Modeling class and see if it is worth paying for or if it something I could teach myself? I am hesitant because there was a $500 107 test prep class that I saw bad reviews for. I ended up buying a test prep book and passing it on my own with a small $25 investment. The 3D Mapping and Modeling seems more advanced, so I was thinking it might be worth the money. I have done 3d mapping on my own before with success, but it seems like there are a lot more applications for it I could learn about. Also the class might be a good resume builder if I were to market myself a expert in the field. What do you all think?
