Inquiry about using GRE physics sub to demonstrate the physics ability

[fsltyan]

Hi I am an international student getting my bachelor's degree this year with computer engineering
I intend to dive into biophysics academia in the future.

But I do not have any physics courses on my transcript. 
In the future graduate application, Can I demonstrate my interest and ability on physics by having the GRE physics like 90% or above and my self-documented course learning experience like Scott Young on MIT open course website?

Yeah, All I do is to avoid doing another undergrad for physics. It's just way too slow and I need to always keep an eye on GPA. I do not like it.....  But if that's the only choice. Ummm I will think twice
I am curious about your opinion~ Thanks for your time~
