Jmc question

I'm from Italy and I've met the requirements for my conditonal Joint Mathematics and Computing offer.
I've been thinking on my choice in the last months and I'm not so sure that I want to do a course as hard as jmc...
Is it possible to change from jmc to computing as soon as I arrive to imperial?

Yup, as far as I know you should be able to change within the first six months if you so wish. Congrats on meeting your offer What grade did you get in the end?

I was aked 95, and I've got 95
