Hey Ratul!!
I hope I'm not too late in replying to your message but I'm Benny and I just finished my first year in Games Technology! Following on from what Patricia said, it is expected to do independent study/ research but they do ensure that the basics are covered to allows us to do so. As you may imagine, the course is very hands-on meaning the focus is using the actual software but it is balanced with the theory ( more so in programming in the first year). There was a lot more programming basics covered in the first year than Modelling and Level Design but at least it allows you to figure out which part of the gaming industry you would like to work for. It would be very helpful to have knowledge in Maths as one unit ( Computer Graphics for Games) do require a decent knowledge on it. Overall it's a fun course and I'm definitely coming back for second year ( Loads more fun stuff to do in second year but it'll be harder for sure)
