Hi, im also an IB student with predicted 41 points but im applying for psychology. I have recently received offers for both durham and st andrews, so those are definitely possible. My brother got 41 predicted last year, and he is now studying at Edinburgh for philosophy and linguistics. So i think that as long as you have a good personal statement, and you have atleast one 7 in your HLs, you should be fine. Im also assuming that entry requirements for history are fairly similar to that of psychology.
