As with other science or engineering careers, you would probably benefit from learning a lot of math, and science, subjects.
I have the same problem. I'm thinking of taking Biology History Law Psychology But really you don't need any qualifications, but it might help you to get in. Choose the subjects you're good at and enjoy.
From what I've learned, you should study subjects like science for enhancing technological skills, math for solving mechanical problems, and arts for unique and beautiful creativities .
Things that are alike but different, or almost complete opposites but still with similarities. if you can choose any 2 subjects choose water and fire damage, because they are very alike and different at the same time.
It depends where you live and go to school.The board of education or its equivalent will decide what are compulsory subjects, how long they should be studied and when you specialise or choose your major and minor subjects.
One option would be architectural engineering.
