Hi there
It is nice to hear that you are thinking about future study options.
For myself, I really enjoyed biology as I could focus on specific topics that really interested me. (I took biology, chemistry and maths). Personally I found biology the most interesting and understandable. I would say that A levels is a large jump from GCSEs, so it would be good to have strong foundations in GCSEs, and you should be willing to put in the hours of studying.
Whether you take a fourth subject really depends on how much work load you can handle. (When I was in sixth form, I remember some students taking four subjects to give it a go, some then dropped one subject afterwards, which is always something you can try.)
For geography, whilst I did not take it myself, I did have a similar moment when I found myself disliking my A level subjects- (Chemistry actually) so it is really up to yourself. During A levels, it is so important to develop a resilient mindset to keep yourself motivated yourself.
Between politics and geography, perhaps you could consider what type of career you would like to enter in the future? You could consider whether you are more likely to benefit from a coursework/ essay based subject.
Also, if you have any particular career that you are interested in, maybe have a look at what entry requirements are needed to get into University. Another thing that could help you make a decision is considering what grades you are likely to achieve if you took those A levels. Having good A level grades could help to widen your future options.
I hope this helps.
