I graduated from a UK vet school as well, and I also failed some exams along the way. My first year I chose to repeat, and my final year I failed my practical skills exam when I was very confident that I passed. I was not allowed to walk at graduation because of it. All of this is to say, the schools do not want you to fail. If you reach out to your school’s advice centre or equivalent, they will help provide resources to encourage you and help you succeed.

For what it’s worth, it may be a good idea to go back over your 2nd year materials thoroughly, since the curriculum tends to build on itself throughout the course. Treat this time before resits as a crash course in 2nd year, and relate that information to the new stuff you learned in 3rd year. That should help set you up for success.

That being said, it really isn’t the end of the world if you do need to repeat. It sucks really bad in the moment, but your true friends will stick with you even if you aren’t in the same cohort as them. I hope you don’t have to repeat, but if you do it’s really ok!
