Better to take easier a levels?

I currently take, history, economics, politics and as sociology I got all A*-As at gcses, however I'm struggling so much with economics because the teacher just cannot teach so I was wondering if it would be better for me to swap economics to make sociology a full a level even though it is not respected or should I stick with economics because it is respected and work harder on my own?

P.S, I want to do law or history at university
