fusion 360 tutor

Hi, I just passed a written exam for 3D printer engineers and hope to pass the next exam on Fusion 360 in two months. I hope someone to help me with this. It has two categories, one of which consists of 19 sets of required design to complete one of them. This should be done in 40 minutes and have it 3d printed. A set of required files and the finished object should be submitted at the end. I am not allowed to access internet during the exam. Another category is to design an engineering product of my choice. I plan to choose a rc plane/drone combination as my project. I should provide design/simulation/manufacture data. I am allowed to access internet during exam and download stl/amf files. My issues for now is to practice the mandatory design within the time frame. I am very slow, so I am looking for ways to speed up. And for the other one, I will need to start from a scratch; Downloading thingiverse files and convert them to editable files. Which should give me a choice to do with my project items for the final category. My budget: USD 150 Duration : 2 months Platform: Github, Fusion 360/Team (mine is Education License)
