The following are major changes that have taken place to the undergraduate Mathematical Tripos courses in the past few years. This does not include minor adjustments to the schedules. The definitive source of current information on the Mathematical Tripos courses is the Course Information page on the Faculty of Mathematics website. All the extra information given here is publicly available on maths.cam.ac.uk or in the online Cambridge University Reporter archive depending on age; records before 1997–98 are only available in dead tree format.
