Im training to be a nurse, but do you think i could be a doctor with these qualifications?

i always wondered if i made a mistake by applying to become a nurse..
the qualifications i have are;
2 grade A*
6 grade A
2 grade B all at GCSE
and a-level I studied chemistry, biology, sociology and psychology and got 3 A's and a B..do you think this would be enough?
will it be enough to get me on the degree?
