Business or Economic A-level with my other options

My current A-Level options are Fine art, Maths, Business and Economics, as well as an EPQ. I want to drop down to 3 subjects and an EPQ. I want to drop either Business or Economics. I have plans of doing architecture or Interior design at university, but I am not completely sure yet. My dilemma is that I am so incredibly lost in Economics, both in macro and micro. I understand that I have only been doing it for 3 and a half weeks, but I am not confident in the subject at all, however from what i know, Econ is more highly regarded at university, and will open more options for me, and both of my teachers are much better than my business teachers. I believe they will help me understand the course as well as they can in the future. As well as the fact that i have many more friends in my class. I am much more comfortable with business at the moment, as I did it for GCSE, and at the moment we are just covering business GCSE topics, however my teachers aren't good at all, and I don't believe that they will benefit me going foreward. I am also aware that business isn't as highly sought after by universities, and I don't want to limit myself by choosing it. I don't want to waste my time by doing both for too much longer, any advice?
