Worth noting that some lectures are NOT recorded. If you are planning on doing a Biology degree for example, the vast majority are not currently recorded. I was an SSLC rep responsible for bringing this up with the staff and the consensus was they didn't really see what the issue with that was, and most were under the impression that they were all recorded. Might be something worth asking about on open days with regards to your own course.
So what were you hoping to study? I know a bit about a few other subjects so might be able to help beyond Biology
