MSc in mathematics from MChem?

I was wondering is it possible to study an MSc in applied mathematics with a background of a masters in chemistry? I have an absolute passion for mathematics and would love the opportunity to study a single year masters.

Would I be given the opportunity to take the entrance exams without formal training? Or would I be discounted instantly?

I have read extensively into the content of the course I have in mind including looking at all their past papers.

I understand it is going to be an individual basis depending on the university and my grades but wanted to hear has someone done or heard of anything similar?
