7-year Med Programs

<p>I am a HS senior and will soon start to apply to colleges. I am like 70% sure i wanna do medicine, and i am thinking of applying to 7-year medical programs. But before I do, i just wanted to know if after doing my 3 years of undergrad, would i be able to use my undergrad degree and apply to an engineering grad school (engineering was just an example, but i meant any other grad school).
Thanks in advance for helping me out =D</p>
