I believe this is the case for most British universities, most "traditional" universities anyway (not sure about former polytechnics, etc). Sometimes there is also coursework that contributes to your final degree (my CS course had a group project in the second year and an a dissertation based on an individual project in the final year), but all the exams take place at the end of the year.

My uni also weighted the exams so that the final year contributed much more to the final "grade" than the first year, effectively putting most of the pressure on the final term of the last year.
