No problem!
Hm...I think it depends on your subject, really. I'm assuming you're trying to pick between Engineering and Physics, so I'll go based on that;
Engineering is something you take with the expectation of becoming an engineer. If you wanted to do Physics later it's not impossible, but you'd find it harder than vice-versa. On the flipside, because there's the expectation of becoming an engineer at the end, you start a working career a lot sooner. In that regard I think Engineering would be "focusing early", although there are still things you can do with it like accounting, teaching etc.
Physics I think is more broad and less 'specialised', if you will, at the cost of no fixed career at the end. You can easily become an Engineer after a Physics degree because the level of Maths used tends to be higher, or you can go into research, teach, work as a medical physicist in the NHS...and so on.
So with that in mind I think the benefit of focusing on a certain field earlier is better for your future, but you run the risk of spending 3 years doing something you end up not that fond of. On the other hand if you're okay with not having a career immediately waiting for you on graduation, you might find your options more open.
Personally I'd go for the more open route, because whatever optimism you have pre-degree you can't guarantee you'll have in 3-4 years time; the ability to do more with your course I would consider a benefit
PS: Sorry this is so long! Truth be told my career path is very specific so I hadn't really thought about the pros and cons before...I hope at least some part is helpful!
