If you don't like Physics please don't take it under any circumstances!!!! And don't choose subjects based on how well you think it's respected by university admissions tutors because as long as you don't take something like General Studies, they really don't care very much and your UMS scores are far, far more important than the subjects you got the UMS marks in. Apart from taking the relevant subject at A level if you want to study it at university (e.g. English Lit if you want to study English at uni), subject choice matters far less to admissions tutors than I think you think it does. It will make your life a living hell for 2 years if you have to spend a lot of time doing a subject you detest.
I took History up to A2 level and am planning to study it at uni next year. I took Edexcel and followed the 16th Century History option.
1st year:
British History from 1509-1540 (25%) which ended with a source based paper,
Luther and the reformation in the Holy Roman Empire 1517-1555 (which I found by far the most enjoyable topic; it was really awesome so I thoroughly recommend it if you have the chance to take this option next year), as well as the revolts in the Netherlands from 1566-160? (sorry can't remember the year the course was wrapped up). Luther and the Netherlands Revolts was examined via 1 exam consisting of 2 essays (25%)
2nd year:
British History (30%) 1536-88 (examined via 1 paper, 1 non-source based essay required and 1 source based)
Coursework (20%): Spain and the Spanish Empire 1474-1598 (for me this was the best part of the course; we could choose our own questions and do all our own research so there was a long rein on it-this coursework structure isn't restricted to the 16th century option for Edexcel; it's the same for all the Edexcel History options)
I think for History it's very useful to look into the board your school does and how everything's assessed, as well as exactly what you'll be studying (which may or may not make a difference to your interest levels). All of this will vary HUGELY from board to board. For History there's a
lot of information to digest and arrange/manipulate, so interest levels are crucial-if you're bored stiff by the subject matter it will be nigh on impossible to learn (at least this is my experience, e.g. when learning about financial reforms in the 1530s!). Having said that, it can be as interesting as you make it, depending on how engaged you are and what questions you ask. Personally I'd thoroughly recommend it, but take that recommendation with a pinch of salt as it depends on how interested you are in studying it in the first place-I think you should be able to gage this pretty well from how much you enjoyed GCSE History.
Difficulty rating (NB very subjective):
If you're really interested in and motivated by what you're studying, 5 or 6
if you're sort of interested/don't mind: 8 or 9
if you don't enjoy it very much, 9-10, if you've taken it as a soft option, 11 (out of 10
)
Hope this helps (although it's obviously only 1 opinion) and best of luck with the eventual decision!
