This is exactly what I'm thinking, I have 3 mocks this week and some next week. I would rather revise and not have to worry about doing well in the mocks.
I really don't like the idea. I'm studying GCSE's and luckily for me my last set of mocks were in January but even they interrupted my study routine. My school put my mocks all into 1 week so most days I had 2-3 exams each day, it was terrible. Also, what is law like? It's not something I'd personally take but I'd like to know more about it though, thanks.
