How to satisfy Graduate Medicine entry requirements?

[2017GraduateStudent]

I am really interested in the medical field, and it has been my life time goal for a while.
I will be enrolling in to Bachelor of Science in Unimelb this year (2018), and I am not familiar with choosing subjects.

As somebody who didn't do VCE chemistry, what subjects would I need to take?
I am aware that the pre requisite for the graduate medicine is:

Anatomy: ANAT20006 Principles of Human Structure
Biochemistry: BCMB20002 Biochemistry and Molecular Biology
Physiology: PHYS20008 Human Physiology

which require these Pre-reqs of:

BIOL10004   Biology of Cells and Organisms   (Physiology and Anatomy)
BIOL10005   Genetics & The Evolution of Life    (Physiology and Anatomy)
CHEM10002   Chemistry 2 (Biochemistry)
   - Chemistry 2 Prereq: CHEM10003   Chemistry 1
                  - Chemistry 1: Prereq: CHEM10007   Fundamentals of Chemistry

So my question here is,

Do the subjects go for a whole year?, or just one semester?,

Because If i were to take Fundamentals of Chemistry and successfully finish it in my first year and semester (assuming that subjects go for one semester)
I will then be required to complete Chemistry 1 for the second semester.

Which implies that I cannot complete Chemistry 2 in my first year?

So how do the system work?
I believe that if aforementioned scenario is true, then it will lock my opportunity to get into Biochemistry due to not meeting the pre requisite of Chemistry 2 in the first year. Hence, lock me out of my hope of Graduate Medicine.

Hope I can get some clarification/confirmations on this..
Please mention if the wording makes it confusing to understand my request.

All the subjects listed are only for a semester. Fortunately chemistry 2 is run during the summer term, for people like yourself and also mid-year entry (and also those that fail it), so that it ensures that you are able to go into second year with the required subjects.

I started mid year so I did chemistry 1 in semester 2. I then took chemistry 2 during the summer which allowed me to do biochem in semester one.
