a level + EPQ decisionWatch this thread
I would not recommend doing 4 A levels - 3 and an EPQ is alright but 4 is too much (remember - AAA is always better than ABBB).
Do not just do history if you don't actually like it, you will literally hate your life (speaking from experience).
To answer your question it would all have to be up to you! But I am taking 3 A levels plus an EPQ and found when applying to top uni’s the EPQ grade I received (A*) didn’t give me any advantage. But personally I would take that over 4 A levels any day I too wish to go into law and any subject combo should work as long as you take two essay based subjects. But what I would 100% recommended is taking subjects that you love rather than what you think will look good to a Uni trust me you will do so much better!!
Although all of these friends did better than me at GCSE, because they had a whole extra subject to focus on, their results at A level were a lot lower
I found researching my own chosen topic more interesting than I think another subject would be and I have been able to use my EPQ as inspiration for essays at university so would recommend EPQ over a fourth A level
