Psychology is a science. It bears very little resemblance to A-level psychology or mainstream/pop culture psychology. You need to be a strong mathematician for statistics, and be prepared for research, philosophy, physiology, psychopharmacology etc. EP at Oxford treats psychology with the academic rigour it deserves, and may not be the best course for every budding psychologist. It is a shame that A-level psychology is not in any way linked to the undergrad degree, which is why Oxford don’t really regard it as academically rigorous enough to prepare their students. OF COURSE, you should try if you want to risk one of your 4, however, proceed with caution. It is incredibly competitive and I am not convinced Oxford will give your A-level predicted grades the credit Im sure you will feel you have earned. PS I have my doctorate in psychology from UCL and get quite frustrated about the misrepresentation of psychology at A-level and the impact on students next choices who take it (like you!).
