Applying to chemistry phd with BS in other field, lack prereqs?

[LastThreeYears]

i'm graduating in next year with a BS in biological sciences focused on biochemistry and molecular biology. however, i've found that the "chemistry" part of biochemistry is more interesting and easier to learn than the "bio" part. found most molecular biology class to be meaningless vocabulary crunching and detail memorization, made harder by being international student. labs also were not much better. this was in contrast to the year of organic chemistry and the labs which while challenging, was so in a way that made me think. i particularly enjoyed the introduction to IR and NMR spectroscopy and the synthesis problems. in addition, IR, NMR and synthesis are concrete skills that make someone a better worker while knowing 90% of molecular biology is useless for the workplace. in the light of molecular biology being both not useful and not interesting, i decided to pursue my graduate education in analytical or organic chemistry, specifically biotech applications such as synthesis and applications of small molecule molecular probes for macromolecule labeling though i'd be fine working with most things outside of quantum and physical chemistry.

the only problem is, because i made a mistake and took the wrong physics class, i can't take a physical chemistry class, so i'm worried that schools will think that i do not have the chemical background to go to graduate school in chemistry. i'm on a tight schedule and tight money so repeat 1 year is too much. is there anything i can do to prove that i am competent enough in chemistry to go to any graduate program? i don't care about ranking of the school since i do not want to go into academia, but would like the rigorous training that a PHD recieves.

Well, at lower rank schools (any outside the top 40) they allow you to have 3 chem classes missing, This includes classes like p-chem, inorganic chemistry, Instrumental anylsis, certain physics, aka. So Im kinda thinking if you didnt take p-chem because of physics you wouldnt of meet the two physics class alone. But if a chem phd is what you want, Im sure theres a program out there for you. Just might go in on probation but chemistry departments are hurting for students.

would getting above 80% on the chemistry GRE test prove competence to make up for the wrong classes?

it's mostly because i was stupid and took "physics for biologists" instead of "classical physics".
