Based on your description, I think you should study Civil Engineering in future. If you like to study engineering, as you mentioned, you should have a strong background in math and physics. To have a strong background in those topics, you should improve your problem solving ability. You should try to solve as many math problems as possible; I think it is the way to prepare for engineering. I think you should also ask your teacher at school to help you improve your math and science skills. Hope it helps.
Best of Luck,
