Cardiff university Law

I’m planning to go to Cardiff for Law. I’m just wondering what the exams are like for LLB. I know there’s like MCTs in the first year. Is that similar in second and third year, or do they scratch that as a whole? Are exams open or closed book and how long are they typically? How many exams would you complete in each year?
I know i have loads of questions, just trying to make sure it’s the right course for me. I’d appreciate it if any Law students at Cardiff could answer!
