Looking for some advice please. I have applied to take the pre-entry course at Strathclyde Uni to enable me to gain access into the LLB next year (fingers crossed)

. The pre-entry course is made up of 3 subjects, as I want to do the LLB i must do law and english, I then have a choice of subject to take as my third. There are several courses from which I can choose some being a language , social studies, geography etc. I wanted to take a subject that may help with my degree later on and the two which i thought may be best were either polictics or psychology(thought this might help if I decided to pursue criminal law).
So any help about which subject would be best from all not just the two I have picked would be great
Thanks
