Hello there,
Yes, as I said above, many, many people have never studied film before and the first year is ideal for bringing everyone up to speed. However, there will be people there that have possible studied film and/or media at GCSE or A-Level and so they will be using certain terminology and stuff that might be new to you in seminars, so just make an effort to do the reading and stuff and you would be absolutely fine.
My timetable was a bit odd, obviously film is your home department but English is in the humanities building, so you are going between places a bit and it can feel a little displacing. There are a few lectures, in film there are lots of screenings too and you are expected to attend them all (whether you do or not is different...) and in English, you are expected to read all the books and do any extra reading for either side of the course in your own time, so that part is very independent. Sometimes you can get away with not having read the stuff, but sometimes you get lecturers that want you to have printed it off and stuff and sneaky ones that may ask direct questions about the reading that you just couldn't make up. Many times I have watched students admit they haven't read it in a seminar haha!
There are examined essays that make up part of your grades throughout the whole year, so expect to be doing a lot of essays. There are only exams at the end of the summer though so don't worry about them. They are very bearable when you manage your time well, it is SO stressful when you leave two 3,000 word essays to the last minute though and then you have to do all the extra reading and formatting and stuff!
Hope I helped, feel free to ask if you need anything else though!
