I did maths at Nottingham and most of the lecturers would just basically read out what was on the slides as opposed to trying to explain things so that was frustrating and I ended up not bothering to go to most of them as a result. I would usually watch the lectures back and slow them down a lot so I could work at my own pace as I felt that would help. It deffo made things difficult but doesn't mean u can't do good. I only went to 3 hours of the lecturers in autumn term of my final year and still got a 2:1 so I wouldn't worry too much
