alevel subject choices help (economics degree)

Im going to study economics at uni and im currently doing
-Maths
-Econ
-physics
-psychology

i want to apply to top unis e.g lse cambridge. Im going to self learn further maths since theres no more space on my schools course, so the problem is that i can't decide wether to drop physics or psychology. with physics i find it really boring and difficult (ik fm will be difficult too but i have a passion for maths so it weighs up) but physics is a rated subject, compared to psychology where anyone can get an a* in psych. so im wondering if i stick to physics (dropping psych) will it up my chances of getting an offer from a top uni or will it not make a difference since both subjects have nothing to do with econ?

just drop phys! as long as you have maths, fm and econ it should be fine. i would not recommend dropping econ - the understanding of the subject displayed through your PS is limited when you don't do econ A level. speaking as a current lse economics offer holder
