no problem! like I said I am more than happy to help
Cons regarding the course and the uni will vary heavily depending on the person - I will speak from experience and my own opinion but that does not mean yourself or others will feel the same. I would say the biggest con of the course is that it can be very tedious at times due to the scope not being very wide. For instance, the course involves very in depth coverage of micro/macro theory, econometrics as well as relevant mathematical/statistical techniques. This is great if you are truly interested in this, however there will inevitably be areas you find boring and the sheer depth of some modules can get pretty frustrating. In my opinion, the course would be better if it cut back on some of the depth and instead increased its breadth to include more coverage of finance, accounting, marketing, entrepreneurship, management etc. That being said, you do have optional modules and there is an optional finance module in second year that you would enjoy given you would like to be a financial analyst. You can also do optional modules from other schools that you are interested in - for instance I did a module from the school of psychology in my second year.
Another con is that the course is very large and so it is very easy to lose touch and feel overwhelmed. That being said, if you find a good group of people and stay active with your course (go to lecturers, seminars and get to know your lecturers) then the size of the course will not be an issue at all - actually it will be the opposite since there are many great people to meet. Just make sure you don't get into a bad habit of not going lecturers and falling behind on work. This leads on to my final con of the course - it is really hard! University is not like school - you won't have teachers chasing after you and making sure you understand everything. You have to do a lot of independent study and a lot of reading. You may find it frustrating that friends on 'easier' courses seem to be going out a lot. Second and Third year are hard and will require a lot of work but thats the case for most courses. The difficulty of first year is really going to depend on your A levels - if you did A level Economics and Mathematics then it will be pretty easy since there will be some overlap. A level Mathematics, particularly statistics, comes in very handy. If you didn't do those A levels, no need to worry, but you will have to study more, simple as that.
Although I talked a lot about cons of the course I really enjoyed it. In my opinion the key to enjoying the course is to make friends on your course and keep on top of work.
The cons of the University are really dependent on the person. For me, I disliked that there was only catered accommodation on the campus as I preferred self-catered. That being said, there are self-catered options just outside campus but because the campus is really big (like really big - you will be walking up a lot of hills) your journey between lecturers, library, gym etc can be quite time consuming. There are free bus services on campus, but like typical British public transport, they are very unreliable. The university is a campus uni and is around 15 mins from the city centre by tram. Some areas in Nottingham have a reputation for being rough (i.e. radford) but I didn't personally experience anything negative in this regard.
There are probably an endless list of cons I could speak about but I did not personally experience any regarding the overall university. I really love the University and am glad I chose it. I should mention though - many have complained about the lack of mental health services. From my experience It seemed that the University was doing a lot in this regard but this is not something I personally dealt with so I cannot really talk further about it.
In terms of things I wish I did differently - rather than joining 5 societies and being loosely involved in them I wish I had joined 2 and been very involved in them. At freshers fair there are so many societies to choose from (over 100) and so it can be tempting to join loads. I highly recommend joining a sports society (if thats not your thing then I recommend joining an activity you enjoy and are interested in meeting people who also enjoy it) and the Econ and Finance society.
Just some general advice: join 2 societies and be very active in them, make good friends on your course and don't fall behind on work, enjoy your first year and really put yourself out there as much as possible, work hard in your second and third year. Finally, University is a place you will develop a lot as a person and learn a lot about yourself - it is not only a place where you go to get your degree.
btw if you have any more questions don't hesitate to ask - I just finished exams yesterday
so I have a lot of time atm.
