Nope. You are only allowed to use 4 out of the 5 choices for 'high risk' courses (med, vet med etc). So you aren't allowed to do that.
Also...there would be no chance of you getting an interview for either med or vet med unless your personal statement shows a definate interest/dedication etc to that subject. Which you can't do if you are apply to both types of courses. I have/am applying for vet med and know that it is expected that your PS will talk about why yuo want to be a vet, work experience you have done etc. I am guessing medicine is the same.
They are fundament differences between the two courses, so if you don't know which you want to do, you will need to look at both and decide. If it is medicine you want, then dont waste your time applying for a totally different course.
